AWS Password reset email not showing up

AWS is supposedly sending me an e-mail to reset my password using my comcast.net e-mail but the e-mail never shows up in my inbox or spam folder or anywhere.  I'm wondering if XFINITY is somehow filtering this e-mail before it gets to me and if there is any way to find this e-mail?  I've tried talking to AWS but they are convinced that it is on the comcast/my e-mail side and won't talk to me about it at all.  Figured I would try one more avenue to get my PW reset e-mail before completely giving up on this account.
