Pre-Sold 3 Subscriptions

So its embarrassing to say this but I used Gumroad to set up a pre-sale process. I had not realized my first sale was over a month ago and was feeling those founder blues not realizing this. I was never notified by Gumroad. I found out on twitter that someone tagged me and advised me that they purchased. This was a bout a week ago. This got lost in my twitter feed @svc2_ I just today signed into my Gumroad account and there were 3 sales. Im excited but stressed that I was never able to get a follow up email out them in a reasonable time at least thanking them.
