yes I have experienced that in the past but dont use it much...we haven't had any reports of issue lately. Did those user check their junk folder? Do they have more than 1 account with the same email? These can be reasons why we think those emails are not working. If that’s not the case, I would suggest you open a ticket.

Would definitely recommend opening tickets with support to report on performance of that function. It can be hard to monitor since those are the one exception to the email cc tracking method of auditing notifications.

I would also consider verifying that you’ve taken the steps detailed in this article. The locations of the settings have changed within the platform but the requirement for having all three MX/DKIM/SPF configured in order to ensure optimal email notifications. It’s also a requirement for support to continue to investigate (they’ll investigate of course but there’s not much they can confirm without those three steps in place.
