Definition
Email revenue per campaign measures the average revenue generated by each individual campaign sent over a given period. It is calculated by dividing total email-attributed revenue by the number of campaigns deployed, producing a per-send financial benchmark. This metric helps marketers compare the revenue output of their campaigns and evaluate whether each new send is pulling its weight.
How It Works
Revenue per campaign is a coarse but useful lens on email economics. It averages across all campaigns, so a single high-performing campaign can mask several underperformers, and vice versa.
- Attribution — the metric depends on accurate revenue attribution, meaning each campaign's conversions are tracked through UTM parameters or platform integration.
- Campaign counting — both broadcast and automated sends can be counted, but the metric is usually applied to one type at a time for fair comparison.
- Comparison value — it is most useful as a trend line over time and as a comparison across campaign types, such as newsletters versus drip-campaign flows.
Because campaigns vary widely in audience size, revenue per campaign is best read alongside revenue-per-email and revenue-per-subscriber, which normalise for send volume and list size.
How to Calculate
Calculate revenue per campaign in three steps:
- Sum attributed revenue — add the revenue credited to email across all campaigns in the period.
- Count campaigns — count the number of campaigns sent in the same period.
- Divide — divide total revenue by the number of campaigns.
Revenue Per Campaign = Total Attributed Revenue / Number of Campaigns
| Variable | Description |
|---|---|
| Total Attributed Revenue | Revenue generated from email campaign conversions |
| Number of Campaigns | Count of campaigns sent in the period |
Example
A brand sends 12 campaigns in a month that together generate £36,000 in attributed revenue. Dividing £36,000 by 12 gives a revenue per campaign of £3,000. When the team reviews individual campaigns, it finds a single product launch drove £9,000 while several others underperformed, prompting a shift in content mix.

Frequently Asked Questions
There is no universal benchmark, since results depend on list size, average order value, and industry. The most useful comparison is against a sender's own historical average and against other campaigns with similar audiences.
Revenue-per-email divides revenue by the number of emails sent, normalising for send volume, while revenue per campaign divides by the number of campaigns. The former is better for comparing efficiency across differently sized sends.
They can be, but they should be analysed separately from broadcasts. Automated flows such as drip campaigns behave differently and mixing them distorts the average.
Campaigns vary in audience, offer, and timing, so large swings are normal. Tracking a moving average and comparing campaign types reduces noise and reveals underlying trends.
