Not receiving verification emails

I am trying to log into a website and it requires email verification.  However, I am not receiving the email verification in my inbox so that I can verify and log in. This even though the host website says that the verification email has been sent.  I've also had someone from their technical department and they do not see any error messages or bounced back emails.  I have deleted all mail filter rules, so this is not the issue.  I've also checked my spam folder and the email verifications are not going there either.  I am not receiving them at all.  Help!
