Open rate averages
The median open rate across all newsletter campaigns in Q1 of 2025 was 49.3%.
The middle half of campaigns recorded an open rate somewhere between 38.9% and 60.2%. Which means if your open rate was above 60% you are in the top 25% of newsletters, and if you are below 39% you are in the bottom 25%.
| Your open rate… | GlueLetter’s evaluation… |
| 22% | Poor (bottom 10% of newsletters) |
| 37% | Lagging (bottom 25% of newsletters) |
| 49% | Normal (better than 50% of newsletters) |

| 69% | Super (better than 90% of newsletters) |
Methodology
Open Rate: GlueLetter calculates this as the email’s unique opens as a percentage of sends. It is the percentage of all recipients who opened the email at least one time.
Privacy related opens: This analysis does NOT exclude any opens from Apple’s MPP, Google image caching, or other similar programs.
