Hey everyone, we switched to a "less hacky" (more expensive) solution to paypal email confirmations. It's pretty barebones HTML right now but it should send without any issues and land in your inbox properly (not spam).
If anyone wants to help us test, I set up a .01 paypal sample button here: (Removed. We've received enough tests, save your pennies!)
An email should be delivered with the subject line: Islands of Nyne: Battle Royale - PayPal Pledge Received!
Please PM me if you tested this and did not receive a confirmation from us within 10 minutes.
Thanks all and apologies for the confusion with this!
