Unblocked eMail

Hello. I have several triggers setup and however the notifications are no longer working. It started 10.09.2022. If I change the email address or the phone number they start working again. It would appear that my original email address and phone number are blocked in your system. What is the process to have them unblocked? My email bosstax@ukr.net, my phone number is +380677520880. Thanks.
