Revenue Per Email
Revenue per email (RPE) is the average amount of revenue generated from each email sent, calculated as total revenue attributed to email divided by the number of emails sent.
What Is Revenue Per Email?
RPE gives you a simple, actionable metric for understanding the monetary value of each email you send. It's calculated by dividing total email-attributed revenue by the number of emails delivered in a given period. For newsletters, revenue can come from sponsorships, paid subscriptions, affiliate commissions, or product sales. RPE helps you make decisions about send frequency — if each email generates $0.50 in revenue and you send weekly to 10,000 subscribers, that's $5,000/week or $260,000/year. This metric also helps you price sponsorships and evaluate the cost-effectiveness of your platform.
Why It Matters for Newsletters
RPE translates your email activity into a dollar value, making it easier to justify investments in content quality, platform upgrades, and list growth. It's also a key metric for pricing newsletter sponsorships — sponsors want to know how much value each email generates.
Best Practices
- Track RPE consistently over time to identify trends
- Break down RPE by revenue source (sponsorships, affiliates, direct sales)
- Use RPE to inform send frequency decisions
- Compare RPE across different content types and formats
- Set RPE targets based on your monetisation goals
