If you're willing to pay for premium, Proton supports custom domains and catch-all addresses, so you can cut out all the extra mail relay stuff. Just give out vendor@mydomain.com, and it all comes back to the same mailbox. If it gets compromised, just set up a rule to trash anything to that address.

Even better is that simplelogin was purchased by proton and it being incorporated into the product. Already mostly done from what I can tell. I started with Firefox Relay and if they even give me a reason to leave I'll just switch over to what's baked into proton. There is something to be said for keeping them separate though. If I ever leave proton, having kept the relay service separate would be a big time saver.
