Deliverability

Hard bounce

A hard bounce is a permanent email delivery failure caused by an invalid or non-existent recipient address.

When an email cannot be delivered because the recipient's address is invalid, closed, or does not exist, it results in a hard bounce. Unlike a soft bounce, which is temporary, a hard bounce indicates a permanent issue. High hard bounce rates can harm sender reputation, so marketers should regularly clean their email lists.
