Notification not being received

Hi @fedsmartsites,
Thanks for your message.

If the notifications are being sent (as shown in the email log) but not being delivered, this points to a potential issue with email delivery.
I would recommend working through the suggestions in this help document to see if it makes any difference to email delivery: https://betternotificationsforwp.com/guides/how-to-improve-email-delivery-wordpress/

Let me know if this helps.

When email delivery fails for a single user, subsequent emails are not sent to the remaining recipients. The error logs indicate a soft bounce followed by a Fallback error stating “Unable to send mail.” We are currently using Post SMTP configured with the Mandrill API for sending emails.

Previously, delivery to other users was unaffected by the failure of one user’s email.

Hi @fedsmartsites,

Nothing has changed in the plugin as far as I’m aware that would prevent emails from being sent after a soft bounce. It’s possible the Post SMTP plugin has recently been updated and has caused this however so it may be worth testing with a version of that plugin from the time when you knew emails were being delivered successfully.
It may also be worth investigating the email account of the user who relates to the soft fail to see if this can be resolved.
