Trying to change contact email (not sign in email) and verification code isn't coming

I am trying to change my contact email (not sign in email), but the verification code never comes. I have had the code sent several times yesterday and today, but it never arrives. It isn't going to spam.

I have checked the email address I entered for typos, and it looks fine. I also went to an email using the address and just copied and pasted it in and it still didn't work.

I don't want to get emails to my main account when people have questions about my webinars! I created this email address specifically for this purpose. 

Any ideas about what to do? Are there any other ways to verify a new contact email address?
