How does Bounce Processing Work?

A bounced address is when an email is undeliverable. There are a few types of bounces that BulkMail processes:

  • A soft bounce
  • A hard bounce
  • A temporary bounce

A soft bounce is a bounce that occurs in situations like “the users’ mailbox is full.”

A hard bounce is a permanent bounce such as “the email account does not exist.”

A temporary bounce occurs when there is a server issue. This bounce is not recorded against the contact as it is very likely that at the next send the email will be delivered.

If it’s a soft bounce, BulkMail will record the bounce against the email address that has bounced but not take any action. If the same email address bounces 5 times it will turn from a soft bounce to a hard bounce. When it becomes a hard bounce, BulkMail will no longer attempt to send campaigns to the bounced email address.

If it’s a hard bounce, BulkMail will record the bounce against the email address and mark them as bounced in your account. BulkMail will then no longer send to that address.

A bounced email address will never be deleted from your BulkMail account. It is given a bounced label next to the email address in your database.
