Q: I received a prompt to enter a code through Account Guard, but I never received an email. Help!top
A: Make sure you're checking the email address associated with your account. Also, be sure to check your spam folder. If you still don't receive an email, contact Customer Support. You may also want to add email@example.com to your email spam whitelist or address book.
Please kindly remember that most mail servers will try once an hour to resend an email if it doesn't do through the first time. (Anything faster is considered abuse by many network admins) You may want to give it a couple of hours if you haven't already. Also only try it once. Anything more than that and you may start getting the codes out of order.
If still nothing, best bet would then be a support ticket.
