Soft bounce indicates an email could not be delivered for temporary reasons. Common soft bounce errors include:
- Email rejected by recipient’s email security filter
- Recipient’s mailbox is full
- Server timeout
- A large email file
After the first soft bounce, most email service providers will continue to try and deliver the email for a few days. Note that after a few attempts to deliver an email if it continues to be unsuccessful, then a soft bounce email address will become a hard bounce and inactive.
