How much does a cold email agency cost?

Why agencies will not give you a number

Ask five agencies for a price and you will get five discovery calls. There is a fair reason and an unfair one. The fair reason: what an agency should charge really does depend on your average deal size and how long your sales cycle runs, because those decide what a booked meeting is worth. The unfair reason: quote-only pricing makes comparison impossible, and that suits the seller. Our position is that the negotiated part being variable is no excuse for hiding the rest. The full technology fee table behind our campaigns is published on the ROI calculator, at all seven volume tiers, at verified list prices.

The three pricing models, and who carries the risk

Flat retainer. A fixed fee every month, results or not. The client carries all of the performance risk: if the campaign underperforms, the invoice does not shrink. This is the model most traditional agencies run, and it is why the first month of a bad engagement costs the same as the first month of a great one.

Pay per meeting. Sounds aligned, but the unit being bought is a calendar entry, not revenue. The incentive is to maximise meetings that clear the definition, and the definition becomes the negotiation. A meeting that shows up and never closes still gets invoiced.

Performance and revenue share. The agency earns an agreed share of revenue from deals it helps source and close. The agency now carries the performance risk, which is exactly why few offer it: it only works if the agency expects its campaigns to close. We wrote a full comparison at revenue share vs retainer, and why teams choose ReplyLead covers the in-house option too.

What the machine costs before anyone writes a word

Whatever the pricing model, someone is paying for mailboxes, a sequencer, data, enrichment, verification and scheduling. This is our own stack, and these are its monthly totals by sending volume, itemised line by line on the calculator:

At the 50,000 tier that $2,841 breaks down into mailboxes and sending infrastructure at $1,412, the sequencer at $699, Clay at $167, Apollo at $149, OpenAI and Anthropic Claude at $99 each, HeyReach at $79, Trigify at $40, ZeroBounce at $28, Make at $29, and Perplexity and Calendly at $20 each. The practical use of this table: it is the floor. An agency quoting far below the tooling line for your volume is cutting a corner you cannot see, usually shared sending domains, skipped warmup or unverified lists, and each of those failure modes has your domain reputation attached to it.

How ReplyLead charges

Two components. A lean amount covers the dedicated sending infrastructure that runs your campaign, the same machine priced in the table above. The bulk of our compensation is an agreed share of the revenue from deals we help you source and close. The percentage and the attribution window are fixed up front, tailored to your average deal size and sales cycle, and there is no long-term lock-in: the goal is that the results keep you, not the contract. For modelling, the calculator defaults your investment to $4,997 a month, and the engagement targets 6 to 16 qualified meetings a month. Full detail is on the pricing page.

What you pay when nothing closes

This is the question that separates the models, and the one quote-only pricing avoids. Under a retainer, a closed-lost quarter costs exactly what a record quarter costs. Under our model, a period where nothing closes owes no revenue share at all: what remains is the lean infrastructure amount, because the mailboxes, data and verification underneath your campaign are real costs that exist either way. That asymmetry is the point of the model. We only earn meaningfully when you do, which is also the strongest signal an agency can send about whether it expects its own campaigns to work. The case studies show what that looks like when it compounds: our longest-standing client has been with us since 2011.

The maths at 50,000 emails a month

Using the realistic benchmark scenario from our calculator, with each lead touched twice: 50,000 emails reach 25,000 unique leads. A 2 percent reply rate returns 500 replies, 15 percent of replies are positive, giving 75 interested prospects, a quarter of those agree to a meeting, around 19 booked, three quarters attend, around 14 held, and a 20 percent close rate signs roughly 3 deals a month. Whether that is a spectacular return or a poor one depends entirely on your deal size, which is why the percentage is agreed per client and why the calculator lets you run your own numbers rather than trusting a generic promise.

Six cost questions to ask any agency

1. Can you itemise the technology cost separately from your service fee? (The table above is what honest itemisation looks like.)
2. Who owns the sending domains, mailboxes and lead lists if we part ways?
3. What happens in the first two to two and a half weeks while mailboxes warm up, and am I paying full rate for it?
4. What exactly do I pay in a month where nothing closes?
5. When is the list verified: live before each send, or once when it was bought?
6. What is the minimum term, and what does leaving cost?

Any agency worth hiring answers all six without a discovery call. If the answer to the first one is a blended number that cannot be broken down, you have learned something useful about the other five.
