How do I get a list of subscribers whose ISPs rejected messages?
When you send a message to your subscribers, sometimes they don't get delivered to everyone. The ISPs of subscribers that rejected your email send us an error message. If the error message is considered valid by our system, we can send you a report of all such email addresses.

Report Definitions
MTA stands for Mail Transport Agent, which is what ISPs use to receive the email we sent them.
The report shows the raw error message received from your subscriber's ISP. These errors were counted as a bounce. If a subscriber receives excessive bounces, their email address will be removed from your list.
