# email.suppressed

> Fires when MailBlastr suppresses a send because the address is on your account suppression list.

The `email.suppressed` event fires when MailBlastr **suppresses an email** — the send was skipped because the recipient is on your account-level suppression list (typically from a prior hard bounce or complaint).

A suppression does not count toward your bounce-rate metric. The `data.suppressed` object explains why the address was suppressed.
