OK... I just noticed the message at the top: "Due to high volume, we are experiencing delays in automated emails. Please allow up to 12 hours to receive a confirmation email." I guess I'll just wait it out with my fingers crossed in hopes all went smoothly.
I made three payments. One with Ether, one with Bitcoin through Shapehsift and one with Litecoin through Shapehsift. I have only received an email about the Litecoin one so far. Will hold and see what happens within 24hrs
