How bounce rate is calculated
Bounce rate is the share of sent emails that couldn't be delivered: bounced emails divided by emails sent, times 100.
Hard bounces mean the address doesn't exist. Soft bounces are temporary, like a full mailbox.
Keep it low
A high bounce rate tells mailbox providers you're emailing addresses you never checked. Verify your list before you send — try the email verifier.
