Email bounce rate

The percentage of emails that are returned to sender as undeliverable.

An email bounce rate is the percentage of emails that are returned to sender as undeliverable. If your bounce rate is higher than 5% then you have a problem with contact info quality that needs to be addressed.

Companies who do a lot of email prospecting need to keep an eye on their bounce rate. Leaving a high bounce rate unchecked will eventually hurt the deliverability of all future emails from your domain.
