What is a Soft Bounce?
A soft bounce is an email message that gets as far as the recipient’s mail server, but is bounced back before it reaches the recipient. One of the most common causes for a soft bounce is a full mailbox. This will happen A LOT with your subscribers who use free email services like Yahoo and Hotmail, because they allow for very little email storage.
A soft bounce is an email message that gets as far as the recipient’s mail server (it recognizes the address) but is bounced back undelivered before it gets to the intended recipient. A soft bounce might occur because the recipient’s mailbox is full, the server is down, the message is too large or the email account is no longer used. Most email service providers will attempt to deliver the email regularly for a few days before finally returning the message as an undelivered soft bounce.The same soft bounce maybe deliverable at another time if the problem preventing delivery is rectified.
