Is your email address still the same as reflected on your domain record? If it is then it could be landing in your junk or trash. If it isn't the same and/or the email is not in your junk or trash, you'll have to contact GoDaddy support to work with them to get you, as the domain owner, authenticated so you can verify and gain access.
