Email Marketing Metrics Explained: What Actually Matters
By Derek Gummersall · Top Tier Emails
Email platforms produce a lot of numbers. Open rate, click rate, click-to-open rate, unsubscribe rate, bounce rate, deliverability score — it's easy to drown in metrics that don't actually tell you whether your email is working. Here's how to think about which numbers matter.
Open Rate
Open rate measures the percentage of delivered emails that were opened. Average open rates vary significantly by industry, but 30–45% is a healthy benchmark for a permission-based list with consistent sends. Open rate is primarily a measure of subject line effectiveness and list health — not of whether your email actually influenced behavior. It's table stakes, not the main event.
Note: Apple Mail Privacy Protection has made open rates less reliable as an absolute measure since iOS 15. Use it as a relative indicator — trending up or down — rather than an absolute truth.
Click Rate
Click rate (the percentage of all recipients who clicked at least one link) is more meaningful than open rate because it requires active engagement. Industry benchmarks for a well-run creator or service business list are 2–6%. Click-to-open rate (clicks as a percentage of opens) measures how compelling your content was to people who actually read it — aim for 10–20%.
Revenue Per Send
For monetized lists, revenue per send is the metric that actually matters. How much money did this email generate? With proper tracking — UTM parameters on affiliate links, unique discount codes for offers — you can calculate this with reasonable accuracy. A list generating $2,000+ per send with 2,000 subscribers is performing well.
Unsubscribe Rate
A healthy unsubscribe rate is under 0.5% per send. Consistently higher rates signal a mismatch between what subscribers expected and what you're delivering. Occasional spikes after promotional emails are normal. Sustained high unsubscribes are a content and expectation-setting problem, not a frequency problem.
