I run a paid service called Kopi that lets you do a similar thing, but it lets you avoid being locked in to your mail provider. One of the reasons I started building it was so I could transition off GMail to something else like Fastmail. I worried that I needed to get off GMail sooner rather than later because the GMail address was slowly spreading out across my online presence and I was getting concerned about the massive hassle that it would be if some Google automated process decided to close my account. But I never got around to it because I couldn’t decide on a mail provider and didn’t want to go through the hassle of changing over all those addresses. Instead I was able to slowly transition all my accounts, etc. over to Kopi addresses. Now that I’m running my mail through Kopi though, I’m not really worried about a Google account shutdown - though I should probably still get off GMail, just feels less urgent now. Kopi works by acting as a “mail forwarder” in between the sender and whatever mail provider you want to use. Of course, you’re still locked in if you use a shared domain like kopi.cloud, kopimail.net, etc. - but you can bring your own domain if you want - you don’t have to be locked in to Kopi. https://kopi.cloud https://kopi.cloud
