Same here, bought 50, nothing in the email yet, probably a system glitch they are fixing.
I bought two $100 AA eGCs about 5 hours ago. I have not received any of the gift card emails yet. Previously I always received the email within a few minutes, if not immediately. I have not even received the order confirmation email! I tried resending the gift cards, and resending page seem to be able to find the purchased gift cards using the email address and confirms that emails have been resent, yet there is no email in my mailbox. I am using a gmail account. Any idea what's going on?
