Email-Attributed Revenue

Revenue generated from customers who converted via a marketing email campaign

What is Email-Attributed Revenue?

Email-attributed revenue is the total revenue credited to email marketing over a period. It counts sales from customers whose purchase is linked to an email campaign under the attribution rule the business has chosen.

It turns email from an engagement channel into one with a clear financial result. It is the natural measure for comparing email with paid and other channels, provided the attribution method is understood.

How this KPI is measured

Function: Marketing
Sub-function: Email Marketing
Industry: All Industries
Type: Lagging
Impact: Revenue
Unit: $
Measurement frequency: Monthly / Quarterly
Formula: Sum of revenue from customers with email campaign as last-touch attribution

How to calculate it

Add up the revenue from customers or orders where an email campaign is credited under your attribution rule. A common rule is last touch: the sale is credited to the last email the customer clicked before buying.

For example, if 1,200 orders in a month were credited to email and their average value was 45, email-attributed revenue is 1,200 x 45 = 54,000.

Be explicit about the rule and the time window, such as purchases within seven days of a click. Different rules give different totals, so keep the choice consistent when comparing periods.

How to improve it

Choose and document the attribution ruleDecide the credit rule and window, and apply it the same way every period.
Tag links properlyUse consistent tracking parameters so purchases can be traced back to specific emails.
Automate high-intent emailsSet up abandoned-basket, welcome and re-order emails that reach people at the right moment.
Segment by behaviourSend offers to the customers most likely to buy, based on what they have done.
Test offers and timingVary the offer, send time and frequency, and keep what earns more revenue.

Tips and common mistakes

Last-touch attribution can flatter email, since it often reaches people who were already about to buy. Consider a holdout group to test true impact.
Read it alongside list size, since revenue naturally grows as the list does.
Discounting to drive email sales can cost more margin than it earns. Check profit, not just revenue.
