Benchmarks for Newsletters and Cold Email](https://www.millionverifier.com/blog/what-is-a-good-email-bounce-rate-benchmarks-for-newsletters-and-cold-email.md) - A good email bounce rate is under 2% of emails sent, with hard bounces under 1%. Investigate as soon as your total reaches 2%. Most email platforms that publish a limit act at 5%, and at least one acts at 2%.
