See exactly how your outreach
turns into revenue.
Adjust the numbers below and watch a cold campaign flow from emails sent all the way to closed revenue and return on investment.
Campaign infrastructure, priced by volume
The sending technology and infrastructure behind every campaign, priced by the number of emails you send. It scales up and down with your volume — change the emails per month above and it moves with it.
The infrastructure fee table, in full
The complete list-price table the calculator uses. This covers the sending technology and infrastructure behind a campaign. The revenue share is agreed separately and is not part of this table.
| Emails per month | Infrastructure fee per month | Cost per 1,000 emails |
|---|---|---|
| 25,000 | $2,023 | $80.92 |
| 50,000 | $2,841 | $56.82 |
| 75,000 | $4,315 | $57.53 |
| 100,000 | $5,531 | $55.31 |
| 250,000 | $12,036 | $48.14 |
| 500,000 | $22,493 | $44.99 |
| 1,000,000 | $44,090 | $44.09 |
Cost per thousand falls as volume rises, from $80.92 per 1,000 at 25,000 emails a month to $44.09 per 1,000 at 1,000,000. The fee moves with your volume in both directions, and there is no long-term lock-in contract.
What the calculator assumes
Every rate below is a model assumption you select, not a measured ReplyLead result. Three scenarios ship with the tool and the calculator opens on Realistic. Your own volume, average deal value, retention and revenue share are separate inputs, so nothing here is forced on you by the scenario you pick.
| Funnel stage | Conservative | Realistic | Aggressive |
|---|---|---|---|
| Reply rate, per unique contact | 1% | 2% | 3% |
| Share of replies that are positive | 12% | 15% | 20% |
| Positive replies that book a meeting | 20% | 25% | 32% |
| Booked meetings that are held | 65% | 75% | 85% |
| Held meetings that close | 15% | 20% | 28% |
The chain runs in this order: emails sent are divided by 2 touches per contact to get unique contacts, then unique contacts to replies, replies to positive replies, positive replies to meetings booked, booked to held, and held to closed deals. Deal value is your average deal multiplied by your retention in months, and total contract value is that figure across the partnership length. Cost is the infrastructure fee for the whole partnership plus the agreed share of closed revenue; return on investment is net over cost.
Two honest limits. These rates are planning assumptions for a model, not a forecast and not a guarantee: a real campaign depends on your offer, your list and your market. And the stages compound, so a small change to an early rate moves the end of the funnel much more than it looks like it should. Change one input at a time and watch which one actually governs your result.
How to actually calculate cold email ROI
Reply rate is a vanity number. The figures that decide whether cold email pays are cost per booked meeting and cost per closed deal - and they are the only outputs the calculator above is really for. Here is the arithmetic it runs, so you can reproduce it by hand.
Start at the top of the funnel and multiply down:
| Emails sent | your monthly sending volume across all mailboxes |
| × reply rate | use a measured figure, not a hoped-for one. Across our published book the median campaign replies from 2.12 percent of contacted leads; anything above 5 percent is a top-decile month, not a plan. |
| × positive-reply share | the fraction of replies that are genuine interest rather than a no or an out-of-office |
| × meeting rate | positive replies that become a held meeting |
| × close rate × deal value | meetings that become revenue, and how much each is worth |
Then divide the total programme cost - every layer, not just software - by the outputs:
- Cost per meeting = total monthly cost ÷ booked meetings.
- Cost per closed deal = total monthly cost ÷ closed deals.
- ROI = (revenue from closed deals − total cost) ÷ total cost.
"Total cost" is the number most calculators quietly understate. It is the technology fee for the sending infrastructure plus data, copywriting, and the reply-handling labour that turns answers into meetings. A programme that looks cheap per send can be expensive per held meeting, which is the only unit that maps to revenue. That is why the model above and the calculator report cost per meeting and cost per deal rather than a headline reply rate - and why our own pricing is weighted to a share of the revenue that closes rather than a flat retainer.
