Soft bounce

A soft bounce is a temporary email delivery failure that occurs for various reasons like a server outage, oversize file or message, or the recipient’s inbox hitting the storage limit. Soft bounces are usually outside the sender’s control. Most soft bounces resolve on their own after a short time. However, if they can’t be resolved, they become re-classified as a permanent delivery failure. In other words, they become a hard bounce.
