Hard Bounce

What is Hard Bounce?

A hard bounce is a type of email delivery failure that occurs when an email message is sent to an invalid, non-existent, or incorrect email address and is returned to the sender due to a permanent error. This is in contrast to a soft bounce, which is a temporary delivery failure that can be caused by issues such as a full mailbox or a temporary server outage.

Hard bounces can occur for several reasons, including typos in the email address, changes in the recipient’s email address, or a complete block on the recipient’s email server. When an email message bounces back due to a hard bounce, it is not delivered to the intended recipient, and the sender receives a bounce error message.

Having a high volume of email addresses that return hard bounces can harm your email deliverability and sender reputation, as it can be a red flag for spam filters. To avoid this, it is essential to maintain good list hygiene by regularly removing invalid or inactive email addresses from your email list.

Campaign Monitor offers a solution to automatically remove hard bounces from your email list, ensuring that you do not continue to send messages to email addresses that are no longer valid. This helps to improve your email deliverability and protect your sender’s reputation.

In conclusion, hard bounces are an email delivery failure that can harm your email marketing performance and sender reputation. Maintaining good list hygiene and using email marketing services like Campaign Monitor can reduce the risk of hard bounces and improve your email deliverability rates.
