What defines a Soft Bounce in email delivery?

A Soft Bounce in email delivery refers to a temporary issue that prevents an email from being successfully delivered to the recipient’s inbox. This can occur due to various reasons, such as the recipient's mailbox being full, their email server being temporarily unavailable, or the email size being too large for the recipient's mailbox limits.

Soft bounces are considered recoverable because they indicate that the email address is valid, but certain conditions hinder delivery at that moment. This contrasts with a hard bounce, which signifies a permanent delivery failure, such as an invalid email address. Understanding the nature of soft bounces helps email marketers and system administrators effectively troubleshoot and maintain their email sending reputations.
