Why are contacts bouncing with a 9.1.5 code?

A 9.1.5 code in your campaign report means that your contact was "auto-bounced" and your message was not sent. "Auto-bounced" is our term for a global system-level suppression. This will happen only if you send a message to one of the addresses we prohibit.

We prohibit sending to these domains:

  • googlegroups.com
  • example.com
  • lettterbox.com
  • notmail.com
  • nowhere.com
  • test.com
  • test1.com

We also prohibit sending to these usernames:

  • postmaster@
  • hostmaster@
  • usenet@
  • news@
  • webmaster@
  • www@
  • uucp@
  • ftp@
  • abuse@
  • noc@
  • security@
  • proxy@
  • proxy-owner@
