Good morning @CDavidson.
Welcome to the forums and thank you for taking the time to post.
I am sorry to hear that you have had some issues with your email address.
Are you able to let me know what emails are you not getting? Are they all emails from amazon or just notifications?
Please could you check to see if they are in your junk mail/ deleted folder? have you checked your filters and rules to make sure that things are all in order there?
Kind regards,
Zak_M
