How Do I Measure the ROI of My Email Marketing Efforts?
Email ROI measurement requires a clear attribution model - knowing which purchases resulted from email vs. other channels. Most email platforms provide this attribution automatically, but understanding what the numbers mean helps you make better investment decisions.
Key Email ROI Metrics
| Metric | How to Calculate | Benchmark |
|---|---|---|
| Revenue per email sent (RPE) | Campaign revenue / emails delivered | $0.10-0.50 per email |
| Email channel revenue % | Email-attributed revenue / total store revenue | 15-40% (varies by store maturity) |
| Automation flow ROI | (Flow revenue - setup cost) / setup cost | Typically 10-50x for abandoned cart |
| Email-first customer LTV | Average LTV of customers acquired through email vs. other channels | Email customers typically have 30-60% higher LTV |
Revenue Attribution: What the Numbers Mean
Email platforms attribute revenue when a subscriber clicks an email link and purchases within an attribution window (typically 5 days for Klaviyo). This has limitations:
- Over-attribution risk: If a customer was already going to buy and happened to open an email first, the email gets credit it doesn't fully deserve
- Under-attribution: Some customers open your email, navigate directly to your site, and purchase - this purchase doesn't get attributed to email
- Best approach: Use email-attributed revenue as a directional metric, not an exact science. Compare campaign vs. campaign, and trend vs. trend.
Email ROI Benchmark Calculation
Example store calculation:
Monthly Klaviyo cost: $200
Email-attributed revenue: $8,500/month
Time invested: 10 hours/month at $50/hour opportunity cost = $500
Total email cost: $700/month
ROI = ($8,500 - $700) / $700 = 1,114% ROI - or roughly 12:1 return
