How Revenue Per Email is Calculated
RPE = Total Revenue ÷ Emails Sent
RPE per 1,000 = (Total Revenue ÷ Emails Sent) × 1,000
RPE is one of the most direct measures of email performance. Unlike open rates or click rates, it tells you exactly how much value each send generates. It's particularly useful for comparing campaigns with different list sizes or send volumes.
Why RPE is the Most Important Email Metric You're Not Tracking
Revenue Per Email (RPE) is widely used internally by SaaS companies and major ecommerce brands, but it's rarely discussed publicly or built into standard ESP dashboards. This is a mistake. RPE gives you a single number that captures the entire performance of a campaign — from deliverability through to conversion — in one metric.
Unlike metrics like open rate or click rate, RPE can't be gamed or misinterpreted. A campaign with a 40% open rate might generate less revenue per email than one with a 25% open rate if the latter converts better or attracts higher-value customers. RPE cuts through the noise and shows you what actually matters: how much money each send generates.
Using RPE to Compare Campaign Performance
Calculate RPE for every campaign you send and track it over time. You'll quickly see which types of campaigns perform best — promotional vs. educational content, product launches vs. newsletters, seasonal campaigns vs. evergreen sends. This data is far more actionable than engagement metrics because it connects directly to business outcomes.
RPE is also useful for segment analysis. Calculate it separately for new subscribers vs. long-term customers, different acquisition sources, or geographic regions. You might find that certain segments generate 5-10x the RPE of others, which should inform how you allocate creative effort and send frequency.
Improving RPE Over Time
There are three main levers for improving RPE: increase conversion rate (better offers, clearer CTAs), increase average order value (upsells, bundling), or improve list quality (better segmentation, removing non-converters). Focus on the lever that's currently weakest in your campaigns for the biggest gains.
