  • Open rate = (Unique Opens / Emails Delivered) x 100

  • Estimated total opens include repeat opens (avg 1.5x unique opens)
  • Use click-through rate alongside open rate for a more accurate engagement picture

About this tool

Your email open rate is the foundation of campaign performance — if subscribers do not open your emails, nothing else matters. This calculator helps you measure your open rate, compare it against industry benchmarks, and get targeted tips for improvement. Keep in mind that Apple Mail Privacy Protection may inflate open rates by pre-loading tracking pixels. For a more complete engagement picture, pair open rates with your click-through rate and click-to-open rate. Improve your open rates with better subject lines and preview text.
