Email Revenue Per Send Calculator
Revenue per email sent is the number I put at the top of every email report, because it survives every argument. It normalizes across list sizes and campaign types and tells you exactly what one address on your list is worth per send.
Result
FormulaRevenue per email sent = (orders × average order value) ÷ emails delivered
Worked example
310 orders at an $86 average order value is $26,660 from 42,000 delivered emails, or $0.635 per email sent. Against a $900 send cost that is a 29.62x return, and $25,760 in profit after the cost of the send itself.
What to watch for
Mature ecommerce programs often see somewhere between $0.20 and $1.00 per email sent on broadcast campaigns, with automated flows well above that range. The spread is driven by average order value and list quality more than by copy.
Attribution windows change this number more than any creative decision. Fix your window (I default to a click-based window measured in days, not weeks) and never compare across two different windows.
Send cost here is the platform and production cost. If you want the honest picture, add the fully loaded hours it took to build the campaign, because that is usually the larger number.
Frequently asked questions
Should I use revenue per send or revenue per subscriber?
Revenue per send for judging individual campaigns, because it holds volume constant. Revenue per subscriber per month for judging the program, because it captures cadence effects that per-send hides.
Why does my flow revenue dwarf my campaign revenue?
Because flows fire on intent and campaigns fire on the calendar. That is normal and healthy. Judge each on its own trailing average rather than expecting a newsletter to behave like an abandoned cart sequence.
