Thanks, joatmon. Same as before — I received a notification here on the forums, but no email notification. This issue has been causing me to miss replies to threads I've authored or commented on in the past and I'm determined to try to resolve it. I hate leaving a thread I've authored "hanging" without a response after another user has taken the time to comment or offer helpful advice.
I just reset my forum password in an effort to "refresh" my previously saved email address on file from my original sign-up back in 2014, which has not changed since. It's a long shot, but I see no other reason in either my User Control Panel settings or personal email settings as to why the email alerts wouldn't be coming through.
