Essential ROI Metrics That Actually Matter
Primary Revenue Metrics
🔢 Conversion Reality: 15.22% of click-throughs from email convert, with an overall conversion rate of 1.06% for all emails sent
Revenue Per Email (RPE) Revenue Per Email measures the revenue you receive for every email sent successfully, giving insight into earnings per campaign. Calculate by dividing total email revenue by delivered emails.

Common ROI Killers and How to Avoid Them
Deliverability Issues
List Hygiene Problems Poor list quality destroys ROI by reducing deliverability and engagement. Verifying subscribers helps weed out invalid email addresses, improving open rates when non-engaging addresses are removed.
Sender Reputation Damage A high spam complaint rate can harm email deliverability and damage reputation with customers. Monitor complaint rates and maintain authentication protocols.
Platform Compliance Ensure GDPR adherence and use double opt-in processes to improve deliverability amid rising scrutiny from inbox providers.
Measurement Mistakes
Attribution Gaps Measuring email marketing ROI isn't always straightforward—the issue is getting revenue and cost figures clear and deciding on attribution. Implement proper attribution models from the start.
Single-Touch Bias Single-touch attribution doesn't provide a full picture of the customer journey and can lead to over-investment in lower-performing channels.
Cost Miscalculation Include all costs: platform fees, content creation, staff time, testing tools, and attribution software. Hidden costs significantly impact true ROI calculations.
Content and Strategy Pitfalls
Over-Automation Balance automation with thoughtful personalization to ensure communications feel authentic, not robotic. Human oversight maintains authenticity.
Generic Messaging Email-active consumers are getting frustrated by constant soulless promo-focused emails. Focus on value-driven content that addresses subscriber needs.
Timing Misalignment Avoid poor timing by monitoring interactions to ensure automated messages are timely and relevant.
Many email platforms can help avoid these pitfalls. For reliable delivery and growing capabilities, explore how to set up Groupmail with SendGrid or SMTP2GO integration for enhanced deliverability.
