Compare your email delivery metrics with top performers in the industry
Sixth Global Email Delivery Benchmark Report Summary
This quarterly report evaluates email delivery performance from April to June 2025 and also contains the SMTP Message of the Quarter, as well as Q2 2025 Email Industry News.
The dataset has been expanded further, providing an even clearer snapshot of MBP email delivery performance. This benchmark offers a valuable baseline for senders to compare and enhance their email delivery metrics. Postmastery commits to releasing these benchmarks regularly, with the next report anticipated at the beginning of Q4 2025.
Key Recommendations
- Secure your messages with the required email authentication : SPF, DKIM, and DMARC are no longer optional.
- Configure your MTA to preserve reputation: convert persistent deferrals into bounces after the first attempt.
- Read SMTP messages from Mailbox Providers: All informations are inside the SMTP answers.
