Mailing Tanks new advanced bounce handling feature allows users to decide which bounces Mailing Tank will take action on - keeping them as bounces or re-categorising them as "active email addresses." The ability to control what is or is not considered a bounce enables marketers to automatically keep subscribers on their active list when, for example, emails were bounced for only temporary reasons. The new bounce category options are:

Blocked: Delivery was blocked by the receiving mail server.
Failed: Email address/user doesn't exist on receiving mail server.
Suspended: Email account is suspended on receiving server.
Soft Bounce: Unable to get a response from the receiving server.
Soft Bounce - (DNS-Related): Unable to locate receiving server.
Temporarily Failed: Temporary outage or offline state of receiving server.
System Misconfiguration: Receiving server not set up to receive email properly.
