How to Measure Email Marketing ROI
The email marketing ROI calculator helps you understand whether your email campaigns are generating more revenue than they cost. At an industry average of $36 per $1 spent, email consistently outperforms other marketing channels — but only when you track the right metrics.
The Email Funnel: Open → Click → Convert
Every campaign passes through three conversion steps. Open rate (typically 15-28%) measures subject line effectiveness. CTR (2-5% of total list) reflects email body relevance. Conversion rate (1-5% of clicks) depends on landing page quality and offer strength. Small improvements compound: raising CTR from 2% to 3% increases revenue by 50%.
Calculating True Campaign Cost
Don't underestimate costs. Include your ESP monthly fee (prorated per campaign), copywriter time at your hourly rate, design or template work, and A/B testing costs. A "free" in-house campaign often costs $300-800 in time when properly accounted for — which still typically yields excellent ROI but matters for accurate benchmarking.
Revenue Per Email: The Key Metric
Revenue per email sent (RPE) lets you compare campaigns regardless of list size. A strong B2C promotional email generates $0.05-$0.20 per subscriber sent. Segmented or triggered emails (abandoned cart, post-purchase) can reach $0.50-$2.00 per email. If your RPE is below $0.02, focus on list hygiene and segmentation before increasing send frequency.
FAQ
What is a good email marketing ROI?
Email marketing averages $36-$42 return per $1 spent (3,600-4,200% ROI), making it the highest-ROI digital marketing channel. B2B email tends to have higher AOV but lower open rates; B2C e-commerce can see ROI above 5,000% with strong segmentation.
How do I calculate email marketing ROI?
Email ROI = ((Revenue from campaign - Campaign cost) / Campaign cost) × 100. Campaign revenue = (list size × open rate × CTR × conversion rate × AOV). Don't forget to include ESP costs, copywriting time, and design in your total cost.
What open rate should I expect?
Average open rates vary by industry: e-commerce 15-20%, B2B SaaS 20-28%, finance 25-30%, nonprofits 25-35%. Below 15% usually indicates list hygiene issues or weak subject lines. Above 30% is excellent.
What click-through rate is normal for email?
Average email CTR is 2-5% of total recipients (not opens). Click-to-open rate (CTOR) — clicks divided by opens — averages 10-15%. Promotional emails typically see lower CTR than transactional or triggered sequences.
