BLUF: My domain registration has been cancelled because I haven't been able to verify my email address, but when I click the "resend verification" link, no verification email is sent.
Long version:
I recently changed the email address on my domain registration. I never received the verification email, but I started getting emails warning me that my registration would be cancelled by ICANN if I didn't verify my new email address. I would click the "resend verification" link, but would never receive a verification email. I wasted a lot of time troubleshooting the wrong end of things: checking SPAM fillets and mail account configuration etc. Yesterday, after my registration was cancelled by ICANN, I finally realized the true cause: I had entered the email address incorrectly and the verification emails were going to a non-existent address. I edited the contact info on the registration to correct the address, and received an email at the new address notifying me of the change, but still no verification email. I clicked the "resend verification" link multiple times over the course of a day, but never received a verification email.
I have tried contacting both email and phone support, but have received no response other than an automatic email reply acknowledging receipt of my support request.
Just now, I tried changing the email address on the registration back to the original address, which I know works properly. This time, I received notification emails about the change at both email addresses, but still no verification email. Nothing in spam folder, either.
I know that I'm able to receive emails from Dyn at these addresses because I'm receiving the change notification emails, but clicking the "resend verification" link still isn't working.
