What's going wrong
Site owners using this mailing list plugin report that messages sent to their list sit in the outgoing queue or never reach subscribers. Plugin checks and test mail pass, so the failure looks hidden. Some see the list address bounce with a relay error, and some say later updates made it worse. The problem appears on free and paid versions and with several mail services, so owners lose hours guessing at the cause. A tool that traces each list message from queue to inbox and names the exact stopping point would give these owners a clear path to a fix.
