What is Soft Bounce?
Quick Answer
A temporary email delivery failure due to a full mailbox, server issue, or message too large.
Soft bounces are temporary failures: the recipient's mailbox is full, the server is temporarily unavailable, or the email size exceeds the server's limit. Unlike hard bounces, soft bounce addresses are potentially valid and can be retried. MisarMail retries soft bounces up to 3 times over 48 hours before suppressing the address. If an address soft bounces repeatedly (3+ consecutive campaigns), treat it as a hard bounce.
