A hard bounce in email marketing refers to an email that fails to deliver permanently. This occurs when the recipient's email address is invalid, nonexistent, or blocked by the recipient's email server. Unlike soft bounces, which are temporary delivery failures, hard bounces indicate a permanent issue with the email address.
A high hard bounce rate can negatively impact your sender reputation and deliverability. It's crucial to identify and remove hard bounced email addresses from your list to maintain a clean and effective email marketing strategy.
By regularly cleaning your email list, you can improve your email deliverability and ensure that your messages reach the intended recipients.
