Email Revenue Per Recipient Calculator
Revenue per recipient is the one email metric privacy pre-fetching cannot touch — it decomposes cleanly into click rate multiplied by the value of a click.

What this result does not account for
- Requires attributable revenue — not applicable to content-only email.
- Flows and campaigns must be measured separately.
- Send cost excludes list building and platform costs.
In short: The metric that cannot be faked. 126 orders at 118.40 across 44,689 delivered is 0.3338 per recipient — and it decomposes exactly into a 2.5644% click rate times 13.02 of revenue per click.
Formula
RPR = campaign revenue ÷ delivered
RPR = click rate × revenue per click
[('RPR', 'immune to privacy pre-fetching'), ('decomposition', 'click rate × value of a click'), ('revenue per click', 'comparable to your paid CPC'), ('marginal recipient', 'worth less than the average')]
Worked Example
- Multiply campaign orders by campaign order value.
- Divide by delivered, not by sent.
- Decompose into click rate and revenue per click.
- Deduct send cost for contribution.
- Value list growth at the same rate — conservatively.
126 orders at 118.40 is 14,918.40 of revenue across 44,689 delivered — 0.3338 per recipient. With 1,146 clicks that is 13.02 of revenue per click, and the decomposition holds exactly: 2.5644% × 13.02 = 0.3338. Click-to-order conversion is 10.9948%, far above cold paid traffic. At 0.0012 per send the campaign cost 53.63 against 6,265.73 of contribution — a return of 116.84 per dollar of send cost. Ten thousand more recipients would be worth 3,338.27 at the same rate.
Strengths & Limits Of This Model
Where this engine is strong
- Uses the one email metric privacy did not corrupt
- Decomposes cleanly into click rate and click value
- Values list growth at the marginal rather than average rate
Where it stops
- Needs attributable revenue
- Send cost understates investment
Practical Use Cases
Valuing an email programme
Using the metric privacy did not corrupt.
Comparing against paid media
Putting revenue per click beside your CPC.
Diagnosing a weak campaign
Splitting click rate from click value.
Valuing list growth
Pricing additional recipients honestly.
Justifying list hygiene
Showing revenue per recipient rather than volume.
Methodology & Editorial Standards
Revenue per recipient divides campaign revenue by delivered messages, and the page identifies it as immune to privacy pre-fetching because no automated process can place an order. The decomposition into click rate multiplied by revenue per click is shown to reproduce the figure exactly, which localises any weakness to either audience or offer. Orders exceeding clicks are refused, since that indicates purchases not attributable to a click in this campaign.
Computation runs in IEEE-754 double precision at full internal precision; rounding to two decimal places occurs strictly at the display layer, so no cumulative drift enters the result. All monetary outputs use accounting presentation — grouped thousands, two decimals, negatives in parentheses — so figures can be transcribed directly into a model or working paper. Division-by-zero and out-of-domain inputs return an em-dash rather than a misleading number.

Email Revenue Per Recipient Calculator — 10 Expert FAQs
10 analyst-written answers to the questions practitioners actually ask — optimised for voice and answer-engine retrieval.
What is revenue per recipient?
Campaign revenue divided by the number of messages delivered. It is the most honest email metric available because it connects directly to money and, unlike open rate, cannot be influenced by a mail client pre-loading images.
Why is RPR better than open rate?
Because a machine can trigger an open and cannot place an order. Revenue per recipient measures an outcome that required a human to decide, click, and buy, which is precisely what privacy pre-fetching made open rate incapable of measuring.
How does RPR decompose?
Into click rate multiplied by revenue per click. That split tells you where to work: a low click rate is a targeting, subject-line or segmentation problem, while low revenue per click is an offer or landing page problem.
Should RPR use sent or delivered?
Delivered, for the same reason open rate should — an undelivered message could not produce revenue. Using sent understates the figure and makes campaigns with poor deliverability look like content failures.
How does email revenue per click compare to paid media?
Usually dramatically better, because the recipient already knows you. Putting your email revenue per click beside what you pay for a click in paid media is one of the most persuasive arguments for investing in list quality.
Is a high return on send cost meaningful?
Only partly. Send costs are trivially small, so the ratio is always enormous and it flatters email badly. It measures the cost of sending, not the cost of building and maintaining the list, which is where the real investment sits.
How should I value list growth?
At revenue per recipient, but conservatively — recipients acquired more cheaply almost always engage less, so the marginal recipient is worth less than the average. Growing the list while holding RPR constant is the genuine achievement.
Does RPR work for non-ecommerce email?
The principle does, but you need a revenue figure to attribute. For lead generation, substitute contribution per lead multiplied by leads generated; for content, the metric does not apply and click rate is your best available measure.
Why is campaign AOV different from site AOV?
Because email audiences and offers differ from general traffic. Promotional sends skew toward lower baskets, while replenishment and winback flows often skew considerably higher. Using site-wide AOV for a campaign calculation is a common error.
Should I include flows or only campaigns?
Measure them separately. Automated flows typically produce several times the revenue per recipient of broadcast campaigns from a fraction of the sends, so blending them produces a figure that describes neither and hides the most valuable part of the programme.
