What the heck is GV mail

I tried lookingall over the internet and cannot find the answer to the question "what is gv mail"

In Zen Cart, "GV" refers to "Gift Voucher", but some folks use "Certificate" instead of "Voucher" in their understanding of things ... so maybe you're referring to something such as Gift Certificates?

The email settings refer to GV mail. Nothing on the internet refers to GV. Must be what you are referring to. Thanks.

I was trying to get notification in change of order status. Right now I go in change the status of order to shipped etc. and even though it says buyer notified...its not arriving. I tried notifying myself to make sure it was working by creating a dummy account. Dang now its working. Using this for process serving instead of selling tangibles.

Status Waiting for docs, Out for delivery, and Served. Pretty neat actually.
