Request for notification on dashboard when there is an error?

I recently had an issue where Google revoked authorization for an unknown reason and emails stopped working. I have searched through this support forum and see many other people having the same issue. I also noticed that there was a feature request to add a message on the dashboard 1.5 years ago, but it seems it hasn’t been implemented. I realize if the email isn’t working, you can’t send an email to notify of the problem, but at the very least a notice on the dashboard would go a long way to bring this to the customer’s attention, so I am adding my request for this feature. As it stands now, the Postman widget on the dashboard, shows a green (everything ok) statement as to how many emails have been sent which makes it look like everything is working. In my case, this is a client’s e-commerce site, which means customers aren’t receiving order confirmations which is a big issue. If there is anything else I can do to get notified when there is this kind of problem that I am not aware of, please let me know! Thank you.
