How to Calculate Email Open Rate
Formula
Open Rate = (Emails Opened / Emails Delivered) x 100
Open rate indicates how well your subject lines and sender reputation attract attention in crowded inboxes. Use delivered emails (not sent emails) as the denominator to exclude bounces, which the recipient never had a chance to see. Note that privacy features like Apple Mail Privacy Protection can inflate open rates by pre-loading tracking pixels.
计算示例
An email campaign delivered 4,000 emails and 800 were opened.
- 01Open Rate = (800 / 4,000) x 100 = 20%
- 02Unopened = 4,000 - 800 = 3,200

How can I improve open rates?
Personalize subject lines, test send times, clean your list of inactive subscribers, avoid spam trigger words, build sender reputation through consistent sending, and segment your audience for relevance.
