How do I get a list of subscribers whose ISPs rejected messages sent from my list?

When you send a message to your subscribers, sometimes they don't get delivered to everyone. The ISPs of subscribers that rejected your message 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.

To view a report of these ISPs, you can either use our web interface or send a command via email.

Using the Command via email:

To see the list of email addresses rejected at delivery, that are considered valid error messages, use the command:


MTA stands for Mail Transport Agent, which is what ISPs use to receive the email we sent them.

This report shows the raw error message we 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.

Helpful Information:
The command SHOWMTAERRORHIST will report the raw data of all delivery rejection messages, since the beginning of your list.

To learn how to send a command to our system, please refer to this lesson:
