One number, three jobs

Revenue per delivered email is the cleanest health metric an email program has: total email revenue divided by total emails delivered. It does three different jobs at once. Per email, it benchmarks your program (ordinary promotional campaigns across the industry land near 10 cents per delivered email). Per campaign, it prices the next send before you plan it. And per subscriber per year, it becomes the input for a bigger question: what a new signup is worth, which is exactly the number our email signup value calculator asks for in its cross-check.

The honesty rules from the rest of this cluster apply here too. Revenue is not profit, so the margin field converts every figure to what you actually keep. And attributed revenue is generous by construction: your platform credits email for orders that clicked an email on the way to a purchase that may have happened anyway, so treat these numbers as email's ceiling, not its floor-to-ceiling contribution.

The formula

Revenue per email = Revenue ÷ (Campaigns × Recipients)
Per subscriber per year = (Revenue ÷ Recipients) × 12     ROI = (Revenue × Margin − Cost) ÷ Cost

Recipients stands in for your active list, which is fair as long as most campaigns go to most of the list; if you segment heavily, use the average actually mailed.

Worked example

A shop attributes $5,400 a month to email, from 8 campaigns averaging 15,000 recipients: 120,000 emails delivered, so 4.5 cents per email, against the 10 cent industry anchor. Each campaign earns $675, and each subscriber produces $0.36 a month: $4.32 a year.

At a 60% margin that is 2.7 cents of profit per email and $2.59 of profit per subscriber per year. Against an $800 monthly program cost (platform plus hours), email clears 5,400 × 60% − 800 = $2,440 a month: $6.75 of revenue per $1 of cost, a 305% ROI on a profit basis.

The 36 to 1 legend, and the two animals in your average

The most quoted statistic in email marketing says the channel returns $36 or more for every $1 spent. The figure comes from industry surveys: self-reported revenue divided by self-reported cost, averaged across respondents who bothered to answer. It is not fake, but it is a revenue-basis average with soft denominators, and comparing your honest profit-basis ROI against it is how a genuinely healthy program gets mislabeled a failure. The example above returns $6.75 per $1 and makes $2,440 a month. That is not losing to the benchmark; that is running a real program while the benchmark runs a survey.

The second honest caveat: your average mixes two different animals. Automated flows (welcome series, abandoned cart reminders) earn on the order of 18 times more per recipient than promotional campaigns, and across the industry they produce roughly 40% of email revenue from about 5% of sends. If your revenue figure includes flows, your campaign RPE looks better than it is; if you have no flows yet, the single highest-leverage move in email is not another Tuesday newsletter, it is switching on the welcome series and the abandoned cart reminder and letting them run. Our cart abandonment calculator prices the second one honestly before any vendor does it dishonestly.

Frequently asked questions

How do I calculate revenue per email?

Divide the revenue your platform attributes to email by the number of emails delivered in the same period, which is campaigns times average recipients. $5,400 a month across 120,000 delivered emails is 4.5 cents per email. Use delivered rather than sent so bounces do not quietly flatter the number.

What is a good revenue per email?

Ordinary promotional campaigns across the industry land near 10 cents per delivered email, with well-segmented programs above that. Automated flows are a different animal entirely, earning on the order of a dollar or two per recipient, so benchmark campaigns against campaigns and flows against flows.

What is RPR (revenue per recipient)?

The same metric under the name Klaviyo and most email platforms use: revenue attributed to a send divided by the people who received it. This page computes it across your whole month; your platform computes it per send. Both are useful, and they should roughly agree.

Is the $36 per $1 email ROI figure real?

It is a survey average: self-reported revenue divided by self-reported cost, on a revenue basis with famously soft cost accounting. Your own program returning $6 or $8 of revenue per $1 of true cost, with real profit left after margin, is a healthy program. Judge it against your numbers, not a survey's.

Should I measure email revenue or email profit?

Track revenue month to month, decide with profit. Revenue per email is fine for spotting trends, but any decision about spending money (more staff time, a bigger platform tier, list growth ads) should use the margin-adjusted figures, which is what the margin field here produces.

Why do automated flows earn so much more than campaigns?

Timing and intent. A welcome email reaches someone at peak interest and an abandoned cart reminder reaches someone mid-purchase, while a Tuesday campaign reaches everyone regardless of intent. Across the industry, flows produce roughly 40% of email revenue from about 5% of sends. If you run no flows, starting there beats sending more campaigns.

Will sending more campaigns increase revenue?

Total revenue usually rises, but the marginal send earns less than the average one: engagement sags and unsubscribes climb with frequency, and unsubscribes are permanent. Price one extra campaign at your current revenue per campaign as the optimistic case, and grow the per-email number through segmentation before growing the send count.

How does this connect to the value of a signup?

Revenue per subscriber per year is the bridge. This page computes it from your real sending data, and our email signup value calculator uses exactly that figure in its list-history cross-check, alongside the cohort math, to put a defensible conversion value on one new signup.
