Key Email Marketing Metrics

Open rate measures how many recipients opened your email, while click-through rate and click-to-open rate measure engagement with the content inside - all core benchmarks for evaluating campaign performance.

Formula

Open Rate = (Opens ÷ Sent) × 100  |  Click-to-Open Rate = (Clicks ÷ Opens) × 100

How to Use This Calculator

Example

5,000 sent, 1,100 opened, and 220 clicked gives a 22% open rate and a 20% click-to-open rate.

What's a good email open rate?

Industry averages commonly range from 15-25%, though this varies significantly by industry, list quality, and subject line effectiveness.
