We've long had a feature we call "Custom Delivery" which lets you redirect customers (after a successful purchase) to your own URL instead of instead of hosting your product's files on Gumroad.
You can probably guess: we've changed that so that it's available to everyone. We see it often used to do things like host paid webinars, online events, and live classes – and in this time especially we think it would be really beneficial for more people to be able to take advantage of.
I also did a really quick (2:44) demo of it on YouTube. If you like it, please like and subscribe :)
Thanks hope you're all safe and healthy,
