Hard Bounces are emails bounces

[Tobi]

Hard Bounces are emails bounces occurred because those email addresses either no longer exist or are incorrect. Regardless of how regularly your ESP attempts, the email won't be delivered since the email address does not exist in any case. Consider them as all-time unreachable addresses. If, however, your email marketing efforts indicate such a large number of hard bounces, most likely your messages are hitting the Spam Filter of the recipient.

Some of the reasons for Hard Bounce include recipient server has blocked incoming email, the address is incorrect, the domain is incorrect or the email address no longer exists.

I believe understanding the causes of hard bounces is fundamental to improving any email marketing strategy. When an email bounces permanently, as mentioned, it's usually because the address no longer exists or is misspelled, and in those cases, there's not much that can be done. However, I also believe that if a high volume of hard bounces is detected, this can be a sign that our messages are being blocked by recipients' spam filters. In my opinion, this can reflect a poor sender reputation or unoptimized sending practices, causing the emails to be considered unwanted. Therefore, it's important to keep the database updated and follow best practices to prevent emails from being filtered. List cleaning and proper segmentation are key to reducing these bounces and improving deliverability.
