This metric evaluates the number of sent mails against the number of bounced or undelivered mails. The metric can be bounce-type specific, for instance, Hard Bounce Rate. Likewise, it can be an aggregate against all bounces versus sent mails. Bounce rates are not always accurate, considering some systems fail to clearly or accurately revert to the sender on why their emails weren’t delivered.
When you divide the number of bounced emails by the number of emails sent and multiply the result by 100, you get the email bounce rate in the percentage form.
(# of bounces* / # of delivered emails) x 100 – your email bounce rate
