E-mail Routing Verification E-mail not coming through


I wonder if someone could help. I am not getting the verification e-mail on one of my three mailboxes.
I have seen similar posts and I think I am also on some sort of suppression list.
What do I need to do?


I also tried to write to s u p p o r t at Cloudflare dot com (from the same e-mail which is not getting the notification) but my e-mail got bounced saying: “Your email to group … was rejected due to spam classification.”
So I am stuck :cry:
