What is Hard bounce?

Definition and meaning of Hard bounce:

A hard bounce is a permanent email delivery issue when you cannot deliver emails to a recipient. Hard bounces happen due to issues like sending emails to invalid addresses or when the receiving server rejects email messages.

When this happens, you will receive a notification that the email was not delivered.

Hard bounces are more serious than soft (temporary) bounces. But, there are tools to help you identify and remove invalid email addresses from your list. So you can ensure your messages reach the intended recipients.

It’s essential to keep an eye out for hard bounces and to make sure your email list is up-to-date and accurate.
