This article explains the difference between soft and hard bounces when sending emails through Presspage, and what to do about them.
It's important to differentiate between hard bounces and soft bounces. Soft bounces occur for reasons that are temporary in nature. The most common reasons are:
- The recipient's mailbox is full.
- The email server is temporarily offline.
- Your email is too large.
In the event of a soft bounce, more delivery attempts will follow, typically within 72 hours. If the email still hasn't been delivered by then, it will hard bounce.
Hard bounces are permanent in nature, and no second delivery attempts will be made. Typical reasons for this are:
- The email address doesn't exist.
- The email address is invalid.
- The mailbox has been disabled.
- The domain name doesn't exist, has been quarantined, or has been suspended by the registry.
- The recipient server has been instructed to reject your email.
- The recipient server refuses to accept your email due to an incorrect configuration on the sending side.
To maintain good list hygiene, remove email addresses that have recorded a valid hard bounce from your email lists. If you think an email address shouldn't have hard bounced, contact Support to look into the error messages together and resolve the issue.
