Cold outreach agencies: the full research

The research was done by AI agents that open web pages. Some sites refuse them; where that happened we say so. The small numbers point to the source list at the end. Where a figure is our own sum or guess, it is marked “our estimate” or “our sum” and the basis is given.

The claim

These are examples of the claim, copied from our collection of 52 tweets about this way of making money¹. View counts are as collected on 6 October 2026. Dates are worked out from each tweet’s ID number. The page judges the method, not the people who tweeted. We read each tweet’s text from our collected file; attached images, videos and threads were not viewed.

“I scaled my agency from 0-$54,000/mo. All I did was send automated emails at scale. But it took 8 draining months to build.”

“I write the cold emails for a lead gen agency that hit $100k/month in 2022”

“I spent 90 days preparing a challenge that will take your Lead Gen Agency from $0 to $10k/mo in 60 days.”

@SmuldersStefan, 15 February 2024, 11,629 views¹

The first two go on to offer a recording or a guide to anyone who follows and comments; the third offers its challenge “for only $198 one-off”¹. The second example does not claim the writer’s own income. It cites an agency the writer works for¹. Other tweets in the set give larger and faster sums; one speaks of more than $70,000 in 57 days¹.

The set is old: 24 of the 52 tweets date from 2021 to 2023, and those hold 973,223 of the 1,270,327 views we collected, about three quarters¹. Seven of the 52 tweets, all from 2021 and 2022, have no view count in our file and are counted as zero, so the older share is in fact higher¹.

What the scheme is

“Lead gen” is short for lead generation: finding possible customers for a business. A cold outreach agency does this for other companies. It sends emails or direct messages (DMs) to people who have never heard of the client. “Cold” means the person did not ask to be contacted. When someone replies with interest, the agency books a sales meeting between that person and the client.

The client pays a retainer, which is a fixed monthly fee, usually whether or not the meetings turn into sales. Some agencies charge per lead or per meeting instead.

The pitch to a newcomer: the software is cheap, one client pays thousands of dollars a month, so a handful of clients makes a large income from a laptop.

The first two parts are true, and the service is a real one. Sopro, a British outreach agency, filed audited accounts showing turnover of £11.5 million in 2025³⁸. The open questions are how many emails a meeting takes, how long clients stay, and how many starters get that far.

Nearly all the evidence below is about cold email, not agencies that work only by LinkedIn or X messages.

The arithmetic

The claimed income is the monthly fee per client, times the number of clients kept, minus tools and labour. A client only stays if meetings arrive, and meetings depend on emails sent, replies, and the share of replies that become meetings.

Step 1: the price per client

Agencies that publish prices mostly charge a few thousand dollars a month.

OutreachBloom: “Starts at $2,400/mo” for 10,000 to 100,000 contacts emailed a month².
CIENCE, a large established firm: $2,000 a month for the team, $499 a month for its software, and a one-time $5,000 setup. Sales staff are extra, at $1,500 to $6,500 a month each³.
Sopro: $4,500 a month for reaching 1,000 prospects, with an estimate of 70 qualified leads. The page says this is “Based on a three-month commitment” and “Excludes one-off set-up fee”; the fee’s amount is not shown⁴.

The tweets speak of $3,000 a month and of “a $60k/year client”, which is $5,000 a month¹. These fit the published prices.

There is also a cheap end, and a newcomer competes against it. Prymatica, a small agency whose revenue is payment-verified (see below), lists a free plan, a managed plan at $495 a month with mailboxes billed extra, and a top plan at $36,000 a year⁷⁵. Cleverly advertises its LinkedIn service “starting at just $397/month”⁷². One tweet in the set asks: “Tired of $1k retainers & free campaigns?”¹

An established agency now publishes a low price for the full service too. Sales.co, whose founders’ account appears below, lists $2,000, $2,500 and $3,000 a month for up to 10,000, 15,000 and 20,000 emails, month to month with no setup fee⁸⁴. A newcomer quoting $3,000 competes with that.

A newer model charges per meeting. A secondary write-up reports a per-meeting formula posted by a seller of cold-email tools in July 2026: $600 a month plus $300 for each booked call, with 10 to 15 calls a client a month⁹⁴. That is $3,600 to $5,100 a client a month (our sum). The write-up’s author read the post from a search snippet, and we did not see it. It is a seller’s formula, not a result⁹⁴.

Step 2: how many clients the claims need

These are our sums from the prices above.

$1,000 a month is less than one client at any of the three agency prices in the list above²³⁴, or two to three clients at $397 to $495⁷²⁷⁵.
$10,000 a month is about 4 clients at $2,400 to $3,000 (10,000 ÷ 2,400 = 4.2; 10,000 ÷ 3,000 = 3.3), 10 clients at $1,000, or about 20 at $495.
“$54,000/mo” is 18 to 23 paying clients at $2,400 to $3,000 (54,000 ÷ 3,000 = 18; 54,000 ÷ 2,400 = 22.5). This is our estimate. The tweet says the climb took eight months; its text gives no client count and no price¹.
$70,000 in 57 days, the sum one tweet speaks of, is about $37,000 a month (70,000 ÷ 57 x 30 = 36,842). At $2,400 to $3,000 that is 12 to 15 paying clients, signed within two months of starting. This is our estimate. The tweet’s text gives no client count and no price, and we did not view the image attached to it¹.

So at full retainer prices the headline numbers do not need many clients. That is the true part of the pitch. The one small agency with verified revenue gets there differently: 24 active subscriptions bring it $4,943 of monthly recurring revenue, about $206 each (our sum)³⁹. Monthly recurring revenue, or MRR, is income from clients on a repeating monthly payment.

Step 3: how many emails one meeting takes

This figure is not in the text of the tweets we read. The sources disagree widely, and almost all of them sell the service or its tools.

Replies. Three companies publish reply rates from their own data for 2025.

Belkins, a large agency, reports 7,530,489 cold emails and 34,393 replies across its client campaigns. It defines the rate as “unique replies ÷ emails sent, excluding auto-replies and bounce notifications”, which gives 0.45%⁵.
Instantly, which sells sending software, reports “a average reply rate of 3.43%” across its users; the top quarter got 5.5% or more⁷. It defines this as “Percentage of all replies received (including follow-up responses) divided by total emails sent.”⁷
Hunter, which sells an email tool, counts per person, not per email: “The average cold email sequence reply rate is 4.5%—for every 1000 recipients that received a cold email in 2025, only 45 replied.” A sequence is the series of emails one person receives. For sales it is lower: “Sales outreach sequences get a 3% average response rate”⁹. Its survey of buyers found: “While 33% say they haven’t replied to any cold emails in the past year, 32% report replying to five or more.”⁹

Belkins and Instantly both divide by emails sent, yet Instantly’s figure is about 7.6 times higher (3.43 ÷ 0.45, our sum). Instantly counts every reply; Belkins counts one per person and drops automatic ones.

When this page was first written we called the rest of the gap unexplained. That is corrected here: a third dataset, read on 7 October 2026, explains most of it. Sales.co counted its own sending both ways: “When we count our own data the Belkins way we get 0.45%, the same figure they report. Counted the Instantly way, with every reply included, our rate is 1.53% of emails sent.”⁸⁵ Seven in ten of all its replies were automatic⁸⁵. So automatic replies are most of the difference, and in two separate datasets a person writes back to about 0.45% of emails sent⁵⁸⁵. Sales.co sells the service, and the data is its own.

From replies to meetings. When this page was first written we said nobody publishes a measured rate for this step. That is corrected here: one agency published one on 6 October 2026. It is the fifth item below. What exists:

Instantly’s blog “Assumes 15% reply-to-meeting conversion”, which gives about 5 meetings per 1,000 emails at its average reply rate⁸. At 20% it would be about 7 (our sum).
Belkins closes its study with one round sentence: “Across 7.5 million emails, we booked over 1,200 appointments.”⁵ Dividing gives one appointment per 6,275 emails (7,530,489 ÷ 1,200, our sum). Belkins states no such rate, and our division does not match the outcomes on its sales pages. Its home page says “We deliver 100–400+ qualified appointments in a year” for a client, and gives average yearly outcomes of “Up to 18,000* prospects” and “200* sales-qualified meetings with decision-makers”⁷⁴. That is one meeting per 90 prospects, and 1,200 appointments would be the yearly output of only 3 to 12 clients (our sums). So the study probably covers only part of the business. We treat 6,275 as an extreme, not a measurement.
Nick Abraham, who runs the agency Leadbird and wrote 7 of the 52 tweets, said on a 2025 podcast that he aims for “one lead per every 350 to 500 uh contacts”¹⁰¹. He also said the agency had “200 plus active clients” and sent “1.5 million cold emails a month”¹⁰. That is about 7,500 emails per client per month (our sum).
A 2024 case study by Smartlead, a sending-tool company, says Leadbird “sends 100000 emails every month” and “books an impressive 800+ meetings per month”¹². That would be one meeting per 125 emails (our sum), a vendor’s claim far better than any other figure here.
Sales.co tracked its own campaign to win clients, from first email to payment⁸⁵. 124,513 contacts received 235,941 emails. 1,169 people wrote back, 296 of them positively, and 143 companies booked a call⁸⁵. That is one booked call per 871 contacts, or per 1,650 emails⁸⁵. This is the only measured figure in the list. It is the firm’s own data, not checked by a third party, and it is for selling an outreach service, not a client’s product. The firm sells cold email, and the result does not flatter it.
The reported pricing formula in Step 1 assumes about 1,000 emails a day for 10 to 15 calls a month⁹⁴. At 21 sending days that is one call per 1,400 to 2,100 emails (our sum), close to the Sales.co figure. It is secondary.

A lead (someone who shows interest) is not yet a meeting, and a prospect or contact usually gets several emails; Instantly’s report calls “4-7 emails” an ideal sequence⁷. So these are not the same measure.

The table shows what each figure means for delivering 10 meetings or leads a month to one client. Smartlead advises: “Keep every mailbox at 50 cold emails a day or fewer.”¹⁷ At 50 a day over about 21 working days, one mailbox sends about 1,050 emails a month (our estimate). Every row is our sum.

Source and what it counts	Rate	Needed for 10 a month, one client	Mailboxes
Smartlead case study, vendor claim: meetings per email¹²	1 per 125 emails	about 1,250 emails	1 to 2
Instantly, assumed: meetings per email⁸	5 per 1,000 emails	about 2,000 emails	2
Belkins home page, promise: meetings per prospect⁷⁴	1 per 90 prospects	about 900 prospects; about 3,600 emails at 4 each (our assumption)	3 to 4
Abraham, podcast: leads per contact¹⁰	1 per 350 to 500 contacts	3,500 to 5,000 contacts	4 to 5 at one email each; more with follow-ups
Abraham, podcast: actual volume per client¹⁰	about 7,500 emails a month	about 7,500 emails	7 to 8
Sales.co, measured on its own campaign to win clients: booked calls per email⁸⁵	1 per 1,650 emails	about 16,500 emails	about 16
Our division of Belkins’ study totals: appointments per email⁵	1 per 6,275 emails	about 62,750 emails	about 60

A fair working range is roughly 2,000 to 10,000 emails per client per month, or 2 to 10 mailboxes (our estimate). The last row is about 30 times the Instantly row (62,750 ÷ 2,000 = 31). Every row comes from a party that sells the service or its tools.

The one measured row, added on 7 October 2026, is worse than the whole of that range⁸⁵. We keep the range because it is what most of the sellers’ figures give, but its top end is the safer assumption (our judgement).

One tweet in the set says “We send 15M+ cold emails per year for 1000+ businesses”, about 1,250 emails per business per month (our sum)¹. Another offers a playbook to “generate 30+ leads/mo for EVERY client”¹. Belkins sells plans of 30, 100 and 200 or more appointments a year, about 2.5 to 17 a month⁶; leads are not appointments, so the two are not the same measure.

The audience matters most. In 2021 the founder of Cold Email Studio wrote: “I send 100 emails to the right audience, I’ll get 10 meetings and close 6 or 7 of them.”⁴³ To close is to sign the customer. He was writing to founders from Y Combinator, a well-known startup programme⁴⁴. It is self-reported and five years old.

Step 4: winning the clients in the first place

An agency normally finds its own clients by the same cold outreach. When this page was first written we found no sourced figure for how many sales calls end in a signed client, and assumed 1 call in 5. That is corrected here. A measured figure now exists, and it is much worse.

In Sales.co’s own campaign to win clients, 7 of the 143 companies that booked a call had become paying customers by 6 October 2026⁸⁵. In its words: “That is 4.9% of booked calls, or one customer per 17,788 contacts emailed.”⁸⁵ That is about 1 call in 20, and about 33,700 emails per paying client (235,941 ÷ 7, our sum)⁸⁵. The 4.9% is a floor, because the latest bookers had only weeks to decide. With only 7 customers the margin is wide: roughly 2% to 10% of booked calls, by the firm’s own statement⁸⁵.

At that rate 4 clients take about 135,000 emails (4 x 33,700, our sum). Our earlier estimate, built on the unsourced 1 in 5 and the working range above, was 4,000 to 20,000 emails. Only our Belkins-derived extreme, about 125,000 (20 x 6,275), came close. All of these are our estimates. Sales.co is an established agency with past results to show, and this is one firm’s own data.

A newcomer with no past results to show should expect to do worse than an established agency. The published accounts of how agencies started bear this out. Cold Email Studio’s founder offered “a campaign of 100 people for free” and wrote “After two weeks I had 7 YC companies I was doing the service for”, unpaid; then he “got the first customer for $500 for the month”⁴⁴. Sales.co ran a free week for three companies and then: “We offered to keep it going for $500/mo, then $1,000/mo, $1,500/mo and eventually $2,000. Two of the companies decided to stay with us.”⁴⁵ Neither started at $3,000.

Sales.co’s two founders also say they did all the work themselves until past $10,000 a month, offered every money-back guarantee, and tried other pricing first: “We failed at several business models initially. A commission-only model, a smaller, per-meeting model.”⁴⁵

Step 5: the costs

Tools are cheap. On this point the pitch is right.

Sending software: Instantly lists plans at $47, $97 and $358 a month¹⁴. Smartlead charges $39 to $379 a month¹⁵.
Mailboxes: Google Workspace Starter is listed at $7 per user per month on a one-year commitment, shown beside a temporary discount for new customers¹⁶. Paying month to month costs more. The page labels the yearly price “Save 16%”, which implies about $8.33 a month (our estimate); the monthly price itself is not displayed¹⁶.
Four clients in the working range need 8 to 40 mailboxes, about $56 to $280 a month at $7 each. At the Belkins-derived extreme they would need about 240, about $1,680 a month. Both are our estimates from¹⁶.

Contact lists were not priced when this page was first written. Two are now read. Apollo lists paid plans at $49, $79 and $119 per user a month, and a free plan with 900 credits¹⁰². Clay lists plans “starting at $185/mo” and “starting at $495/mo”¹⁰¹. One list-and-sending product, ListKit, starts at “$597 per month for 1,000 emails per day”⁵⁶.

Put together, the tools to serve one client at 10,000 emails a month, the volume Sales.co gives for $2,000⁸⁴, cost roughly $170 to $370 a month (our estimate). That is about 10 mailboxes at 50 emails a day, $70 to $85¹⁶¹⁷; sending software, $47 to $97¹⁴; and contact data, $49 to $185¹⁰¹¹⁰². It leaves out domain names, checking that addresses are valid, a paid LinkedIn seat and all labour.

Labour is a cost the text of the tweets does not mention. Sopro’s audited accounts show wages and salaries of £7.16 million against turnover of £11.52 million, about 62% (our sum)³⁸. A person working alone pays this cost in their own hours. We found no measured figure for hours per client. The only one is a seller’s estimate. An earlier version of this page gave it as 4 to 6 hours a week for each client, taken from a search summary. That was wrong and is corrected here from the article itself. Puzzle Inbox, which sells mailboxes, puts labour at “5-8 hours/month per client”, and writes: “The agencies that struggle are the ones spending 15-20 hours per client per month because they have not systematized their workflows.”¹⁰³ It describes a founder doing everything alone at 5 to 10 clients and making a first hire at 10 to 20¹⁰³. It gives no data behind these figures.

Two tweets in the set state a cost, both for AI tools: one sets $1,184 spent on AI agents against $47,300 in a month, and the other $100 a month against $3,500 to $12,000 a month¹. Neither tweet’s text gives a client count or labour; their attached images were not viewed.

Step 6: what the text of the tweets does not say

The 30 most-viewed tweets hold 1,241,461 of the 1,270,327 views¹. They give income totals and sometimes a price per client or a number of days. One says how hard the time was (“8 draining months”)¹.

In the text we read, none states a reply rate, a meeting rate, how many sales calls end in a signed client, how many clients leave, refunds, hours worked or profit¹. Attached images, videos and threads were not viewed, so some of this may be given there. Only one gives a client count beside an income figure: “$6M ARR” and “1000+ businesses”¹. ARR means annual recurring revenue. The tweet names two agencies, so the income and the client count cannot be divided to give a price per client. Another says “115 clients” three years after starting, with no income figure¹. Mostly, the text of the claims gives the result of the multiplication and not the numbers that were multiplied.

What people who tried it report

We found no dataset of outcomes. No study, survey or platform says what share of people who start a cold outreach agency ever sign a client, what the middle one earns, or how long they last. What exists is payment-verified revenue for a few operators, founders’ own stories, audited accounts for one large firm, and customer reviews.

Payment-verified small operators

TrustMRR is a site where businesses connect their account at Stripe, a card-payment company, so the revenue shown is read from the payment processor. The figures are revenue, not profit, and miss clients who pay by bank transfer. Profile text is written by the owners, who chose to publish and are probably doing better than most. Our notes do not record how these profiles were chosen, so treat them as examples, not a full count.

On 7 October 2026 we checked for more. TrustMRR’s public list holds 11,378 startup pages⁸². In two separate checks we picked about 75 and 29 profiles whose names suggested leads, outreach, cold email, agencies or sales, and opened each one. Neither check found a further cold outreach agency with meaningful revenue⁸²⁸³. The outreach profiles with real revenue were software (see “Tools and platforms” below)⁸³. The limit: we matched on names only, so an agency with an unrelated name would be missed.

A new agency. DirectB2BLeads gives its founding date as 2 November 2025. The date is self-reported and the profile names no founder, so we do not know the founder’s experience. Its first Stripe revenue came in February 2026. Monthly figures: February $2,000, March $7,000, April $7,400, May $4,600, June $5,570, July $7,250, August $4,350, September $899, and October $2,000 by the 7th. That sums to the “Last 12 months | $41,069” on the profile, about $4,900 a month over the eight full months (our sum)⁴⁰. It describes itself as “Done For you. Performance-Based.” and says one service “is billed per lead”, one is a monthly fee and one “is priced per project”⁴⁰. So it is not a pure retainer agency, and its “Current active subscriptions: 0” may only reflect that kind of billing. The profile also shows a 70.0% profit margin for the last 30 days⁴⁰. A second read on the same day showed the same totals⁴⁰.
A three-year survivor. Prymatica, a cold email and LinkedIn agency founded in July 2023, shows “Last 12 months | $133,308” and “All time | $358,617”³⁹. That is about $11,000 a month on average over the year (our sum). Revenue fell four months running, from $13,634 in May 2026 to $7,023 in September³⁹. An earlier version of this page said five months; May itself was up on April’s $11,530³⁹. Monthly recurring revenue is $4,943 across 24 subscriptions, down 29.2% in 30 days³⁹. Its average subscription is about $206 a month (our sum, Step 2), and its price list starts with a free plan and a $495 plan³⁹⁷⁵. An earlier read on the same day showed $133,587 for the last 12 months, with the same all-time total; the 12-month window moves each day³⁹. This page uses the later read, which also showed $6,818 for the last 30 days³⁹.
A larger, mixed business. Upscale System LLC shows $88,406 in the last 30 days and $614,671 in the last 12 months⁴¹. Its description says “We sell CRM and Lead generation softwares.” Its profile also calls it “a done-for-you outbound growth partner for B2B companies”⁴¹. B2B means business-to-business. Its recurring revenue is $102,183 across 296 subscriptions, about $345 each (our sum), which looks to us like software or low-priced plans⁴¹. The revenue is not split between the two, so we do not count it as agency retainer income.
A nearby business we left out. A further profile sells “Exclusive lead generation for Concreters, Roofers, Builders & Earthworks” and shows $855,845 all time⁷⁶. It does not say how the leads are found, and its payment data has not updated since February 2026, so it is not counted as a cold outreach agency.

For scale: one tweet in the set says its author’s agency reached “$54,000/mo” after eight months¹; the one new agency whose revenue we could verify took $41,069 over about eight months of revenue, with a best month of $7,400⁴⁰. One agency’s record does not show whether another’s claim is true.

Founders’ own accounts

None of these is payment-verified.

Cold Email Studio (2021). Its founder, a software developer, wrote “last year, I couldn’t even sell my own car”⁴³. He reported “Month 0 - $500”, “Month 1 - $5k”, “Month 2 - $8k”, “Month 3 - $10.5k”, selling to Y Combinator founders⁴³. A later interview reports $14,000 a month with 2 full-time and 4 part-time staff, prices “starting at $2k per month”, and says “The number one obstacle for me was pushing through burnout”⁴⁴.
Sales.co (2024). In a February 2024 podcast the founder, a former salesman, said “we are at roughly 75k mrr” with six or seven people, after a “90k month or 95k month” in December⁴⁶. A July 2024 profile shows revenue of “$90K a month” and says the partners had “already hit 10K MRR” four or five months in⁴⁵. The podcast dates the start to the end of 2022⁴⁶, so the $90,000 came about a year and a half after starting (our inference).
ZenOutreach (2021). Its founder, a law graduate who had run a letting agency and worked as a sales manager, reported $6,000 a month after less than a year, with two part-time employees, and said “Margins are now a lot higher (70-80%)”⁴⁷.

Each founder had run a business or product before, and each aimed at one group: Y Combinator founders for the first, other agencies for the third⁴³⁴⁴⁴⁷. An earlier version of this page said each sold to a group they “already had a way into”. The sources do not show that, and it is corrected here. Cold Email Studio’s founder built a list of about 100 Y Combinator founders from a public directory and cold-emailed them; he chose startup founders because “It’s what I know”⁴³⁴⁴. His interview says: “We primarily use cold email as a sales channel.”⁴⁴ ZenOutreach’s founder names “Email outreach mainly from the start until now and networking in different Facebook groups for entrepreneurs”⁴⁷. The Sales.co account does not say where its first three free clients came from⁴⁵. Two of the three accounts are from 2021, before the inbox rules described in the next section. Sales.co’s two founders met through a following on X; one was a career salesman with a funded product, and the other had run data companies⁴⁵.

A fourth account, read on 7 October 2026, is far larger and comes from a firm that also sells to would-be agency owners. ColdIQ says it grew from a side project in January 2023, with a first client at $3,000 a month, to over $300,000 a month by January 2025⁷⁷. Its founder had run cold outreach at every earlier employer, and his first client came from readers of his own blog⁷⁷. The details are in “The upside” below.

Where the first three are now. This was an open item when the page was first written. We checked on 7 October 2026. Sales.co is trading, with a 10-person team and the prices in Step 1; it states no current revenue⁸⁴. It says: “Across 421+ clients in four years we have generated 14,000+ leads.”⁸⁴ The address coldemailstudio.com no longer shows the 2021 agency. It now carries a service selling leads to firms that lend to businesses, and we could not tell who runs it or whether the agency was sold or closed¹⁰⁵. Our agents could not open the address zenoutreach.com, which may only mean it blocks them; we do not know whether the agency still trades¹⁰⁶.

A large agency’s audited accounts

Sopro’s filed accounts are the strongest proof that companies pay for this service, and also the clearest warning. “Group turnover for the year was £11.5m, compared with £13.2m in 2024.”³⁸ That is a fall of 13% (our sum). The directors wrote: “Demand across the B2B sales and marketing market softened during the year, and pressure on client acquisition and retention reduced revenue. The Group reported a loss after taxation of £0.66m (2024: £0.15m loss).”³⁸ The accounts also name “AI-enabled tools competing for the same budgets” as a risk, and show an average of 269 employees³⁸.

An insider on timing

Nick Abraham wrote in an August 2026 tweet in our set: “Scaling a lead gen agency in 2026 makes doing it in 2022 look like child’s play. It’s way harder to do today than it’s ever been. If I were trying to get mine back to $6M ARR starting today, I would focus on these things: 1. Build undeniable social proof.”¹ We read the words “back to” as meaning the figure is a past one (our reading). On the podcast he said it takes “60 90 days” to know whether a campaign works¹⁰.

We have not checked his revenue. His published client counts rise over time and may count different things (active against all-time, one agency against two): 115 in a January 2024 tweet¹, “over 120 active clients” in the 2024 case study¹², “200 plus active clients” on the 2025 podcast¹⁰, and “1,000+” in a July 2026 tweet that also says he “bought into another lead gen agency”¹. Leadbird’s home page shows “1,000+ Active Clients” and, lower down, “2M+ cold emails/month across 100+ clients”¹¹.

A measured decline. Abraham’s view now has support from data that does not come from him. Sales.co counted 1,279,153 contacts first emailed between April 2025 and September 2026⁸⁶. It reports: “In April 2025, 2.36% of contacts sent a human reply and 0.72% sent a positive one. By September 2026 those were 0.45% and 0.18%.”⁸⁶ A human reply is one a person wrote, not an automatic one. September was still collecting replies; August, with more time, stood at 0.56%⁸⁶. The rate also fell inside 8 of the 9 clients active in both periods, for example from 2.03% to 0.82%⁸⁶. The firm’s own volume grew 27-fold over the window, which it names as a limit on the finding⁸⁶. It sells the service, and it publishes the data files behind the figures⁸⁶.

Clients leave

A client who gets no meetings cancels, and the agency must replace them.

Cold Email Studio’s founder wrote that “many early customers churned” and “we’re hoping to get 3-6 months” from a customer⁴³. Churn means clients leaving.

On Trustpilot, a review site, the outreach agency Cleverly has 1,155 reviews: 88% are five-star and 2% one-star⁵⁰. One of the one-star reviews, a customer’s own unverified account from June 2026, says: “Not a single lead, not a single outcome, thousands if dollars spent”⁵⁰. Another says “In two months, my campaigns got only 2 replies” after “wasting $4000”; a third, from January 2025, reports one lead in three months⁵⁰. Cleverly works mainly through LinkedIn and has replied to some of these reviews⁵⁰. They are a small minority of that firm’s reviews, and reviewers choose themselves.

Published percentages for how many clients leave are weak. A consultancy page says “67% of companies report outsourced partner performance below expectations in year one”, naming no underlying study⁵¹. A tool vendor writes that “month-4 churn typically runs 25–40% across the category”, which is the author’s impression, not data⁵². We found no reliable figure.

Three more pieces, read on 7 October 2026, do not change that.

An anonymous seller offering a cold-email agency for sale on Acquire.com, a marketplace for small businesses, writes: “Monthly churn is approximately 15%, which is consistent with the lead generation agency model.”⁸⁰ At 15% a month the average client stays under seven months (1 ÷ 0.15 = 6.7, our sum). The same listing also states 80% yearly client retention; the two cannot both hold⁸⁰. It is one seller’s statement.
Sales.co’s own counts, 421 clients and 14,000 leads in four years, come to about 33 leads per client over each client’s whole stay, and about 105 new clients a year (our sums)⁸⁴.
For marketing agencies of all kinds, not outreach agencies, a 2026 survey report says: “Only 3% of agencies say their typical client relationship lasts 36 months or longer”; 57% report 12 to 24 months¹⁰⁴. Its publisher, CallRail, sells call-tracking software to agencies. We did not capture the survey’s size.

Stories that could not be checked

A 2026 case study of “$30,000 monthly recurring revenue in six months” was anonymous, showed no payment record on the page we read, and was published by a company that sells cold-email services⁴⁸.

One tweet in our set announces an interview titled “From $0 to $42,000/mo lead gen agency in 5 months”¹. A post with the same title on a Gumroad page named coldemailwizard says: “just did an interview with one of our clients inside Client Ascension”⁴⁹. Client Ascension is a coaching programme (see below). We believe this is the interview the tweet points to, but did not follow the tweet’s link. We read the post’s text only and did not watch the interview, so the figure is unchecked⁴⁹.

We searched in five wordings for a write-up by someone who started such an agency and gave up, and found none. Reddit blocked our agents. This is a gap in our search, not a sign that failures are rare.

The general base rate

Of new US professional-services businesses with employees, 74.5% were still open after one year and 50.8% after five⁵⁴. For all industries the figures are 77.9% and 51.4%⁵³. Solo agencies are not in these tables.

The field is crowded, and more so each year. The Clutch directory lists “3,095 Companies” under lead generation, including firms that work by phone⁵⁵. Archived copies of the same page showed 783 firms on 22 October 2022 and 1,994 on 1 July 2024⁹⁷. That is about four times as many in four years (our sum); part of it may be Clutch itself growing as a directory.

Filtered to firms with 2 to 9 staff, the directory shows 1,155 companies, about 37% of the total (our sum)⁹². Those on the first page show client reviews and minimum project sizes of $1,000 to $10,000⁹². So small firms do hold paying clients. A listing is not proof of profit, and Clutch may be paid for placement⁹².

Instantly’s home page showed “10,000+ clients” in July 2023, “20,000+ customers” in July 2024 and “30,000+ customers” in July 2025⁹⁸. One operator who reports large revenue writes: “Lead generation is one of the most commoditized markets on the planet. Thousands of agencies make the same claims, copy the same tutorials, and chase the same clients.”⁷⁸ Commoditized means buyers see every seller as much the same.

What the rules allow now

The law depends on where the recipient is

United States. Cold email to businesses is legal if it follows a law called CAN-SPAM. The email must be truthful about who sent it, carry a postal address, and offer a way to opt out that is honoured within 10 business days²⁸. The Federal Trade Commission (FTC), the US consumer regulator, says: “The law makes no exception for business-to-business email.”²⁸ And: “Each separate email in violation of the CAN-SPAM Act is subject to penalties of up to $53,088”²⁸. The agency shares the risk with its client: “Both the company whose product is promoted in the message and the company that actually sends the message may be held legally responsible.”²⁸

We found enforcement only against a large company: in August 2024 the security-camera firm Verkada agreed to pay $2.95 million to settle FTC charges, “the largest penalty obtained by the FTC for a CAN-SPAM violation”²⁹. That case concerns Verkada only. We found no regulator action against any account quoted or named on this page, and we do not suggest any connection. We found no FTC case against a small cold-email agency. States add their own rules; Washington bars a subject line that “contains false or misleading information”³⁷.

Other countries are stricter.

Germany treats as an unacceptable nuisance “advertising using an automated calling machine, a fax machine or electronic mail without the addressee’s prior express consent”, with no exception for business recipients³².
Canada requires consent. It is implied in a few cases, one being where the recipient “has conspicuously published, or has caused to be conspicuously published, the electronic address”, has not refused such mail, and the message is relevant to their work⁷³. “The maximum penalty for a violation is $1,000,000 in the case of an individual, and $10,000,000 in the case of any other person.”³³
Australia: “Even if someone else is sending out your marketing messages for you, you must still have consent from each person who will receive your messages.”³⁶
United Kingdom: “you can send B2B direct marketing emails or texts to any corporate body”, but “sole traders and some partnerships are treated by PECR as individual subscribers”, so consent is needed³⁴. PECR is the UK’s rule set for electronic marketing.
France allows emailing professionals without prior consent if they are told and can object³⁵.

The mailbox providers’ own terms

The usual setup is many mailboxes on Google Workspace or Microsoft 365, driven by sending software. Both providers’ terms are against it.

Google’s acceptable use policy for Workspace forbids using it “to generate, distribute, publish or facilitate unsolicited mass email, promotions, advertisements, or other solicitations”²³. Gmail’s policy says the same of “unsolicited commercial mail”²⁴. Google adds: “we reserve the right to immediately suspend the user. If the problem is domain-wide, we reserve the right to suspend the entire account”²⁵.
Microsoft says “aside from the High-volume Email offering, Exchange Online doesn’t support bulk or high-volume email”²². Exchange Online is its business email service.
Mailchimp, a mainstream email marketing service, forbids sending to “purchased, rented, third-party” lists, among others²⁶.

So the business can be stopped by a suspension, and mailboxes and domains are lost with it²⁵. No provider publishes how often that happens. Tool fees are not returned either: Instantly’s terms say “ALL FEES PAID UNDER THIS AGREEMENT ARE NON-REFUNDABLE AND NON-CANCELLABLE.”²⁷

Delivery rules have tightened since most of these tweets

Gmail caps each paid Workspace user at 2,000 messages a day¹⁸.
Since 1 February 2024, Google tells senders to “Keep spam rates reported in Postmaster Tools below 0.3%”, which is three complaints per thousand emails. Postmaster Tools is Google’s dashboard for senders. Senders of more than 5,000 messages a day to Gmail accounts must also set up authentication, a technical proof that the mail comes from the domain it claims¹⁹.
“Starting November 2025, Gmail is ramping up its enforcement on non-compliant traffic”, including rejecting messages²⁰.
Since 5 May 2025, Microsoft rejects mail to Outlook.com, Hotmail and Live addresses from domains sending over 5,000 a day that fail authentication²¹.

One point cuts the other way. Google says: “The Email sender guidelines don’t apply to messages sent to Google Workspace accounts.”²⁰ Much business email goes to company addresses, so those thresholds do not bind it directly.

LinkedIn and X

Writing to people on LinkedIn by hand is allowed. Automating it is not: LinkedIn does not permit software that will “automate activity on LinkedIn’s website”³⁰. It adds: “Repeated suspensions may result in permanent restriction of your LinkedIn account.”³¹

The free limits are tight. LinkedIn says of a free account: “You can add a personalized message to up to three connection requests per month”⁹⁵. Sales Navigator, LinkedIn’s paid tool for finding prospects, is listed at US$119.99 a month or US$1,079.88 a year for its basic plan⁹⁶. Buyers may prefer this channel: in Hunter’s survey, 50.5% of decision makers preferred LinkedIn for outreach, against 25% for email⁹.

X’s rules on bulk DMs could not be opened when this page was first written. We have now read them in an archived copy dated 1 October 2026; X’s own help page still refused our agents¹⁰⁰. The rule says: “You may not send unsolicited Direct Messages in a bulk or automated manner, and should be thoughtful about the frequency with which you contact users via Direct Message.”¹⁰⁰ A recipient who follows you, or who has open DMs, has not consented by that alone, and scripting the website can bring permanent suspension¹⁰⁰. DMs written by hand, one person at a time, are not covered by this rule¹⁰⁰.

Who makes money from it

Who the tweets are aimed at

Most of the 52 tweets are written for people who want to run an agency, not for companies that want meetings¹. We labelled 29 as follow-and-comment posts: posts that promise to send something to anyone who follows and comments¹. By our labels, made from the text of the tweets, 9 show nothing for sale and the other 43 lead to a free guide sent by DM, a course, coaching, a community, a paid challenge or the author’s own agency or software¹. Three accounts wrote 24 of the 52¹.

The three most-viewed tweets, 465,324 views together, are from one account and all ask the reader to follow and comment¹. Such a post brings its author followers and a list of people who asked to be messaged (our reading).

Coaching and courses

Prices we could find:

A $198 challenge. “a challenge that will take your Lead Gen Agency from $0 to $10k/mo in 60 days … I’m giving it away for only $198 one-off.”¹ It is the only price stated inside the tweet set.
CCCS and Closing Clients Group. One tweet promotes a coaching product it calls CCCS, which our collection labels Closing Clients System¹. We did not find its price. A related membership, Closing Clients Group, is listed at “$97/month” or “$799/year”, and its site treats Closing Clients System as a separate product⁶¹. The Group’s refund policy says: “All subscription payments, coaching services, and digital product purchases are final.”⁶² The Group has 54 Trustpilot reviews, 98% of them five-star; none of the results members describe is verified⁶³.
Client Ascension, whose own account is in the set¹: no price on its site. Its home page shows results such as “$100,000/mo (USD) in 9 months” and states: “These results are not typical or guaranteed.”⁵⁸ On Trustpilot it has 311 reviews and a 4.7 score, 96% five-star⁵⁹. Among the low-star reviews, which are customers’ own unverified accounts, one from October 2026 says “I was being offered a $12,000, 6-month programme” on a sales call and did not buy; the company replied, disputing the reviewer’s account. One from October 2024 says “we committed $10,000” and saw no return; the company replied that the reviewer had not followed its instructions. One from August 2025 says “I did not receive a single qualified lead for $8000+ spent on the system”; the company replied: “Client Ascension does not sell a lead service. It’s a coaching program.”⁵⁹
AV Mastermind, a 24-week coaching programme for lead gen agencies. A third-party review says: “AV Mastermind does not publicly display its pricing.”⁶⁴ Its author promotes a rival programme. We have not confirmed who runs the programme.
ColdIQ’s community. ColdIQ, an agency whose own revenue account is in “The upside” below, runs a community for agency owners on Skool. Its pinned post says: “We’ve helped over 116 agency owners add between $5K and $70K in MRR using these systems.”⁷⁹ It gives no count of members, so no success rate can be worked out, and the claim is not verified⁷⁹.

No programme we found publishes how many of its buyers end up with paying clients.

Tools and platforms

These are paid monthly whether or not the buyer ever signs a client.

Sending tools: $39 to $379 a month¹⁴¹⁵.
Instantly pays people who refer customers a share of each subscription, every month. Its page’s headline says “between 20% and 35%”, and a tier list on the same page goes up to 40%: “Earn 40% commission on referrals starting from the 76th”⁶⁵. So someone who teaches cold email can earn when a student signs up.
Skool, which hosts paid communities, charges group owners $9 or $99 a month⁶⁷. It pays 40% of that fee for life to whoever referred the owner: “If somebody creates a group from your group, we attribute it to you automatically.”⁶⁶
ListKit, a cold-email data and sending company, reports “10,000+ paying customers” at prices from $597 a month⁵⁶⁵⁷. Its About page says its co-founder and chief executive “also runs Client Ascension, a coaching program for agency owners”, and lists a second co-founder as a co-founder of Client Ascension⁵⁶.
ColdSire, which sells mailboxes for cold email at “$6/mo per account”, shows payment-verified revenue of $266,071 in the last 12 months, about twice Prymatica’s $133,308⁴²³⁹. Its monthly revenue roughly halved over the year, from $29,361 in November 2025 to $15,258 in September 2026, and it is listed for sale at $215,000⁴².
TheMailSupply, which sells “done-for-you cold email infrastructure”, shows payment-verified revenue of $374,710 all time, but $22,290 in the last 12 months and $617 in the last 30 days⁹⁹. With ColdSire, that makes two payment-verified sellers of cold-email mailboxes whose revenue has fallen sharply⁴²⁹⁹.
In our TrustMRR check of 7 October 2026, the outreach businesses with real payment-verified revenue were tools, not agencies. Prosp, a LinkedIn outreach tool founded in August 2025, shows $398,093 in the last 12 months⁸³. That is about three times Prymatica’s $133,308³⁹.

A regulator case about a different kind of coaching

We know of no connection between Growth Cave, the company in this paragraph, and any person or company named on this page. We found no court or regulator action against a cold-email agency course, against any programme named above, or against anyone in our tweet set. The nearest case we found concerns a different product: coaching for starting an online business. These cases concern the companies named in them only. We found no regulator action against any account quoted or named on this page, and we do not suggest any connection. In February 2025 the FTC sued Growth Cave, which sold coaching for starting an online business at “$3,500 to $50,000 each”. The complaint alleges: “In most instances, KBA purchasers do not make a single sale and therefore do not earn any income.”⁶⁸ KBA is the short name of the programme. The FTC headed its announcement “FTC Takes Action to Stop Sprawling ‘Growth Cave’ Business Opportunity and Credit Repair Scam”⁶⁹. The word is the FTC’s and applies to that case only. The case ended in January 2026 with a settlement and a partly suspended judgment of $48,597,538. The charges were settled by court orders, not decided at trial; the FTC’s announcement does not say the defendants admitted them⁷⁰. We have not looked for a public reply from Growth Cave.

In January 2025 the FTC asked for comment on extending its rules on earnings claims to business coaching⁷¹. We did not check the outcome.

The upside

It can work. Companies pay several thousand dollars a month for this service²³⁴. Some agencies have grown large, and a few small ones have payment records to show.

Nobody publishes how agency incomes are spread. So we cannot say what the top tenth or the top hundredth earn. What exists is a set of single cases. They are sorted here by who vouches for the figure.

Figures and rankings checked by a third party

Audited accounts: Sopro. Turnover was £13.2 million in 2024 and £11.5 million in 2025, with an average of 250 employees in 2024 and 269 in 2025, and a loss after tax in both years³⁸. The company was incorporated on 2 September 2016⁹¹. So it took about eight years to reach £13.2 million (our sum).
Ranked by Inc., no figure shown: CIENCE, SalesRoads and Belkins. Inc. is a US business magazine that ranks fast-growing private companies. CIENCE, founded in 2015, was on its Inc. 5000 list four years running: No. 112 in 2019, 793 in 2020, 588 in 2021 and 971 in 2022⁸⁷. SalesRoads, founded in 2007, was listed in 2014, 2015 and 2024⁸⁸. Belkins, founded in 2018, ranked No. 35 in 2023 and No. 20 in 2024 on Inc.’s regional list for the Mid-Atlantic states⁹⁰. Under the rules for the current round, entry to the Inc. 5000 needs at least $2 million of revenue in the latest year, and the regional lists need at least $1 million; Inc. asks applicants to verify their figures⁸⁹. We did not read the rules for the earlier years in which these firms were listed. Inc. shows no revenue figure on any of the three profiles, so these are rankings, not checked sums⁸⁷⁸⁸⁹⁰. Inc. describes CIENCE as running “multichannel campaigns” and SalesRoads as an “appointment setting, lead generation and sales outsourcer”, so neither is presented as an email-only agency; neither profile mentions courses for would-be agency owners⁸⁷⁸⁸. An earlier version of this page said both use the phone; the profiles do not say so. These are firms built over years.
Payment-verified: Prymatica. $358,617 since July 2023, and $133,308 in the last 12 months, about $11,000 a month (our sum)³⁹. It is revenue, not profit, and it fell for four months running in 2026, to $7,023 in September³⁹.
Payment-verified: DirectB2BLeads. $41,069 in the eleven months since its stated founding, with $7,000 in its second month of revenue, a best month of $7,400 and a worst full month of $899⁴⁰.
Verified by a broker, in a nearby model. Empire Flippers, a broker that sells online businesses and says it checks sellers’ revenue, lists a subscription lead-generation business for financial advisers and B2B sales teams⁸¹. Its first revenue came on 2 May 2024. It first tried to sell software and switched to its present model in late 2024 or early 2025⁸¹. The listing shows revenue of $106,772 and net profit of $63,713, an asking price of $143,355, and about 5 hours of owner time a week⁸¹. The listing calls it an agency, but it does not run campaigns for its customers: “Campaign creation and ongoing campaign management are handled by the customers themselves.”⁸¹ An earlier version of this page inferred that the figures cover a year. That is withdrawn. The listing says it “uses a shorter financial reporting period” because of the change of model; it does not give the length, so we cannot say what period the $106,772 covers⁸¹.

These are still the only payment-verified cold outreach agencies we found. A fresh check on 7 October 2026 added none⁸²⁸³.

The operators’ own figures

No one else has checked any of these.

ColdIQ, started January 2023. Its guide gives a dated path: “first client at $3K/month, six clients and $15.7K MRR by May 2023, $30K/month by October 2023, $150K MRR by July 2024, and a first $200K month in September 2024”⁷⁷. It reports over $300,000 a month by January 2025⁷⁷. That is the most detailed climb we found, and it is the firm’s word alone: two years from nothing to over $300,000 a month. Its two guides give different yearly totals, perhaps for different dates. One guide’s title says $4 million a year; a second says $6 million a year from about 70 clients⁷⁷⁷⁸. That second figure is about $7,100 a client a month (our sum). The firm sells on the subject. The guide sits behind an email form, the same page sells a managed service and software plans, and ColdIQ runs a community for agency owners⁷⁷⁷⁹.
What ColdIQ’s founder started with. He had run cold outreach campaigns at every earlier employer. He was already writing about sales tools to earn referral fees, and his first client was a software founder who had read his blog⁷⁷⁷⁸. It was still slow: “The first month of posting generated zero leads; the model takes months to compound”⁷⁷. His first cold campaign, in the guide’s words, “flopped almost completely”, and one client never paid a $4,400 invoice⁷⁷.
An agency offered for sale. A listing on Acquire.com offers a cold-email agency, founded by its account in February 2025, for $3.2 million⁸⁰. It states revenue of $1,926,737 over twelve months and seller’s earnings, the profit an owner takes, of $929,490⁸⁰. Acquire’s own note reads: “Business address and incorporation certificate verified (US entities only).”⁸⁰ It checked nothing else that we could see. The seller is anonymous. The listing’s headline gives lower figures than its table, and it states both 80% yearly retention and about 15% of clients leaving each month⁸⁰. We treat it as an unchecked claim, not a measurement.
Sales.co. “$90K a month” about a year and a half after starting, by its founders’ account in 2024⁴⁵⁴⁶. It is still trading in October 2026 and states no current revenue⁸⁴. One founder sells lead lists⁴⁵; its home page offers no course⁸⁴.
Cold Email Studio and ZenOutreach. $14,000 a month and $6,000 a month, both reported in 2021⁴⁴⁴⁷. We could not confirm in October 2026 that either still trades: one address shows a different business and our agents could not open the other¹⁰⁵¹⁰⁶.
The tweets. We did not check “$6M ARR”, “$100k/month” and the rest: we read the text of the tweets only¹.

The top of the field

No source ranks agencies by income. Two rank senders by results.

Instantly says the top 10% of senders on its platform get a reply rate of 10.7% or more, against 5.5% for the top quarter and 3.43% on average⁷. The top tenth get about three times the average (our sum). This counts every reply, covers all users and not only agencies, and comes from a tool vendor.
Across 15 Sales.co campaigns of 5,000 or more contacts, the middle campaign got a positive reply from 0.11% of contacts⁸⁵. The top quarter got 0.51% or more and the best got 0.94%; the bottom quarter got 0.06%⁸⁵. So a top-quarter campaign draws more than four times the positive replies of a middling one (our sum).

Replies are not income. But they show how far the best campaigns sit from the middle.

A realistic good result

This estimate is for a starter who has already sold or run a business and knows one group of buyers well. It is not for a starter without those. It rests on thin evidence: one verified new agency⁴⁰, one verified survivor³⁹ and three self-reported founders⁴³⁴⁵⁴⁷. Time to a first payment ran from under a month to between three and four months⁴⁰⁴³. After that, roughly $2,000 to $10,000 a month of uneven revenue in the first year, with a real chance of sliding back when two or three clients leave. That is revenue before tool costs and your own hours. The top of the range rests on founders’ own accounts, two of them from 2021⁴³⁴⁵⁴⁷. The verified new agency averaged about $4,900 a month (our sum); its best month was $7,400 and its worst full month $899⁴⁰. Most starters probably do worse, because people with poor results rarely publish them. The three-year survivor averaged about $11,000 a month over the past year and took $7,023 in September 2026³⁹. We found no payment-verified case of $10,000 a month within 60 days. Nothing read on 7 October 2026 changes this estimate.

For comparison, a salaried job doing the same work pays from the first month. A sales development representative is an employee who books meetings for a company’s sales team. One article puts US base pay at $50,000 to $68,000 a year in 2026, or $65,000 to $95,000 with commission at target⁹³. That is secondary: its author’s company sells a sales tool, and we could not open the source behind it. The base pay is about $4,200 to $5,700 a month (our sum), inside our first-year range for an agency before costs.

What it takes to compete

What the people who succeed have

The four founders who published their story share most of these⁴³⁴⁵⁴⁷⁷⁷. It is their own account. We do not know the background of whoever runs either payment-verified agency³⁹⁴⁰. We found no account from anyone who gave up, so we cannot say how many people with the same advantages failed. These are traits of the known successes, not a tested recipe.

You know one group of buyers well before starting. Cold Email Studio’s founder, who had built startups himself, cold-emailed about 100 Y Combinator founders from a list he made, first with a free offer⁴³⁴⁴. ZenOutreach narrowed to agencies and used email outreach and Facebook groups for entrepreneurs⁴⁷. ColdIQ’s first client came from its founder’s own readers⁷⁷. Sales.co’s two founders met through a following on X; their account does not say where the first clients came from⁴⁵. The best rates we saw came from a founder writing to people like himself: about 10 meetings per 100 emails, by his account⁴³. Only one of the four clearly began with an audience of his own⁷⁷.
You have run a business or sold before. All three founders had. One said he had no sales skill, but he had built companies⁴³⁴⁴. ColdIQ’s founder had run outreach at every earlier employer⁷⁷. You must win clients on sales calls against thousands of listed firms⁵⁵.
You pick a narrow group and know it. In Sales.co’s data, “A contact at a company with 1 to 10 employees was about seven times as likely to reply positively as one at a company with 1,001 to 5,000”: 0.48% against 0.07%⁸⁵. Chief executives and other top officers replied positively at 0.35%, vice-presidents at 0.15%⁸⁵. In Hunter’s data, sequences sent to 21 to 50 people got 6.2% replies, against 2.4% for lists over 500; the average sequence went to 449⁹. ColdIQ names as a starting need one outreach skill “you can credibly dominate”, beside a LinkedIn presence and the setup to send 500 cold emails a day⁷⁸.
You do not rely on tricks. Sales.co found that first lines written by AI for each person did worse than a plain template: 0.53% against 1.00%⁸⁶. Instantly credits its top senders’ results to “micro-segmentation, problem-focused messaging, frequent A/B testing and smart automation”⁷. Micro-segmentation means small, closely defined lists; A/B testing means sending two versions to see which does better. That is the vendor’s reading, not a controlled test.
You can start free or cheap. The documented starts were free campaigns, then $500 a month⁴⁴⁴⁵.
You can go months without income from it. The verified new agency’s first payment came between three and four months after its stated founding⁴⁰. ColdIQ’s first month of posting brought no leads⁷⁷.
You send only where the law allows it, and do the daily work of keeping mail out of spam folders¹⁹²⁸. In Hunter’s data, mail from a company’s own domain got 5.2% replies against 2.5% from free mail accounts, and 20 to 49 emails per mailbox per day did best, at 5.7%⁹.

What it costs

Tools are the small part. Roughly $170 to $370 a month for each client served (our estimate, Step 5). A paid LinkedIn seat adds US$119.99 a month⁹⁶.
Winning a client is the large part. At Sales.co’s measured rate of about 33,700 emails per paying client⁸⁵, a newcomer using cold email alone would need about 30 mailboxes running for a month to win one client (our estimate, at about 1,050 emails per mailbox a month¹⁷). A newcomer has no past results to show and should expect worse. The documented starts that used cold email began with free work for a narrow group the founder knew, or leaned on an existing audience (our reading)⁴³⁴⁴⁴⁵⁷⁷.
Price pressure. An established agency gives up to 10,000 emails a month for $2,000, month to month⁸⁴.
Your hours. A vendor that sells mailboxes puts labour at 5 to 8 hours a month for each client once the work is systematised, and 15 to 20 hours a month at agencies that have not done that¹⁰³. It is a seller’s estimate, not a measurement. At the one large firm with audited accounts, wages took about 62% of turnover (our sum)³⁸.
Time. In Sales.co’s data the middle booking came 9 days after the first email, but 34% of bookings came more than a month later⁸⁵. So a campaign cannot be judged in its first two weeks. Abraham says it takes “60 90 days” to know whether a campaign works¹⁰.
Coaching is optional. Prices we found run from $198 to five figures (see “Coaching and courses” above)¹⁵⁹. No programme publishes its buyers’ results.

How to tell early which side of the line you are on

By about month 4: has anyone paid you anything? In every case above, someone had; the slowest, the verified new agency, took its first payment between three and four months after its stated founding⁴⁰⁴³⁴⁵.
Count positive replies per 1,000 new contacts. About 1 is the middle of Sales.co’s campaigns; 5 or more is its top quarter⁸⁵. Sales.co advises: “If you compare your own campaign with a published average, the median is the fairer yardstick.”⁸⁵ The median is the middle value.
Watch the bounce rate, the share of emails that cannot be delivered. A practitioner quoted by Hunter names a rate above 2% as a warning sign; the average in Hunter’s data is 3.6%⁹.
After a client’s first three or four months: did they stay? One founder hoped for 3 to 6 months per client⁴³; a vendor puts the main drop at month 4⁵². Neither is data.
Count meetings against emails sent, not replies against emails opened⁵, and compare with the table above.
Compare what you have spent on tools, lists and coaching with what clients have paid you.

It is a sales job with clients who leave, not passive income.

What we did not verify

The income claims. We did not check “$54,000/mo”, “$100k/month”, “$42,000/mo”, “$6M ARR” or the tweet that speaks of $70,000 in 57 days: we read the tweets’ text from our collected file, did not view attached images or videos, opened no profile, and found no filing or payment page for them elsewhere.
Outcomes for starters. No dataset gives the share who sign a client, typical earnings, client turnover or how long agencies last. We found no spread of agency incomes (a middle figure, a top tenth), no course that publishes its buyers’ results, and no group of beginners with published outcomes.
The rates in the arithmetic. The steps from reply to meeting and from meeting to client now have one measured figure each. Both are Sales.co’s own data on its own campaign; no third party has checked them, the customer rate rests on 7 customers, and the firm’s volume grew 27-fold during the decline it reports. The 4 emails per prospect is our assumption. The Belkins emails-per-appointment figure is our division of two of its totals. Instantly does not say whether negative or automatic replies are counted.
The upside figures. ColdIQ’s revenue has no filing, payment record or outside check; its pages give $4 million and $6 million a year, and only the open part of each guide was read. The Acquire.com listing’s accounts sit behind a paid tier, its seller is anonymous, its date is unclear and the business was not identified. The Empire Flippers listing says its reporting period is shortened but does not give its length. How Inc. checks revenue was not read beyond its statement that applicants are asked to verify their figures, and its entry rules for the years before the current round were not read. Belkins’ revenue: only outside estimates were found, and none was used. Sales.co’s client and lead counts are its own, and its current revenue is not stated.
Whether the traits separate those who succeed from those who do not. The list in “What it takes to compete” comes from four founders’ own accounts. No account of a failure was found to compare them with.
Whether the list of payment-verified agencies is complete. The check of 7 October 2026 matched on profile names only and read owners’ own descriptions. An agency under an unrelated name would be missed. TrustMRR’s full search needs an account.
The people behind the profiles and handles. We do not know the experience of whoever runs DirectB2BLeads. No X profile was opened, so we have not confirmed which named person runs which account.
Exact wording of some quotes. The Smartlead case study, Closing Clients Group’s home page, Cleverly’s Trustpilot totals, the ICO, Clutch and the FTC’s CAN-SPAM guide were read through a tool that summarises pages. The two podcasts are automatic transcripts. The July 2026 pricing post was not seen; it is reported by a blog that read a search snippet.
Secondary figures. The pay range for sales development jobs comes from a tool vendor’s article; its underlying source refused our agents. The size and date of the CallRail survey were not captured.
Prices. The price of CCCS; Client Ascension’s and AV Mastermind’s prices and refund terms; hired help; domain names and address checking; whether Apollo’s listed prices are for monthly or yearly billing. Google’s month-to-month mailbox price is inferred from a “Save 16%” label, not read.
Crowding. Whether Clutch’s rise from 783 to 3,095 firms reflects more agencies or only more listings. The count of 1,155 small firms assumes the size filter in the address was applied; only the first page was read.
Rules not read. LinkedIn’s weekly invitation limit as a number, the law in Brazil, Poland, the Middle East and other EU countries, rules on cold calls and texts, and any state, non-US or private legal actions. X’s rule was read in an archived copy, not on X’s own site.
Failures. Reddit was blocked directly and through a reader, and we found no write-up by someone who gave up. Upwork, where freelancers sell this work cheaply, also refused our agents, so we read no earnings record there.
Current state. Who now runs coldemailstudio.com, and whether the 2021 agency was sold or closed. Whether ZenOutreach still trades. Who runs AV Mastermind. Whether Growth Cave has replied publicly to the FTC’s charges. Whether Sales.co’s 2024 figure of $90,000 a month still holds.

Items settled on 7 October 2026 and moved out of this list: a measured rate from reply to meeting and from meeting to client (Steps 3 and 4), X’s rule on bulk DMs, prices for contact data, whether Sales.co is still trading, and the wording of the hours-per-client estimate (Step 5), which was read on the vendor’s page and corrected.

Sites that needed a reader service (r.jina.ai) because the direct fetch failed or returned almost nothing include Leadbird, Microsoft, Gumroad, Client Ascension, Hunter, Indie Hackers, Failory, Trustpilot, Prymatica, Sales.co, Inc., Acquire.com, Empire Flippers, Clutch, Clay, Apollo and Puzzle Inbox; each source entry says which route was used. Old Clutch and Instantly pages and X’s rules were read at web.archive.org.
