I have Newsletter Plugin Version 3.4.8. One month ago I successfully sent a newsletter. I’ve made no changes to the plugin since the last newsletter.
This month I sent a newsletter but no one received it although the plugin shows a status of “sent”. I tested via the Diagnostic page using “Send an email with WordPress” and “Send few emails with Newsletter”, but did not receive any emails. I called Go Daddy, my hosting provider, and they were able to upload an email php script that successfully sent an email.
I’m not sure what steps to follow to diagnose the problem. Any suggestions?
UPDATE: I turned on Debug logging on the Diagnostic page and tried sending a newsletter to my test users and also through the Diagnostic page. Here is the log that was produced:
