Revenue Per Email Sent (also called RPE or revenue per send) is a key metric for comparing campaign efficiency over time and across segments. It accounts for both engagement and conversion in a single number.

Revenue Per Email Sent: The Metric That Connects Email to Business Outcomes

Revenue per email sent (RPE) is one of the most direct ways to measure the financial impact of an email campaign. By dividing total attributed revenue by the number of emails sent, you get a single figure that represents the average return generated for every email in the send. This metric makes it easy to compare campaigns side by side, track performance over time, and forecast expected revenue from future sends based on historical baselines.

A typical e-commerce email generates somewhere between £0.05 and £0.50 per email sent, though high-value promotional campaigns for premium products or highly engaged segments can significantly exceed this range. The metric is most useful as a relative comparison tool — your own trend over time is more actionable than any industry benchmark.

Revenue Per Open vs Revenue Per Email Sent

While revenue per email sent measures overall campaign efficiency, revenue per open isolates the performance of the content itself. If your RPE is low but your revenue per open is strong, the problem is deliverability or open rate — not content. If revenue per open is also weak, the issue is email content, offer relevance, or landing page quality. Using both metrics togethter helps you pinpoint exactly where the revenue funnel breaks down.

Improving Revenue Per Campaign

Revenue per campaign improves when you increase any of: open rate (better subject lines, send time, list quality), click rate (better content and CTAs), conversion rate (better offers, personalisation, landing pages), or average order value (product recommendations, bundles, upsells). Segmentation is typically the single largest lever — sending financially relevant offers to segments most likely to buy consistently produces higher RPE than broadcasting the same offer to the full list.
