- My Proton address doesn’t get given out to anyone since it’s simply the backend I abstracted away with other domains.
- I use my primary domain for my personal email and all the important services (banks, healthcare, etc.), and things like GitHub that are tied to me. I also use it for all the services I self-host.
- The alias domain is for everything else. Newsletters, services, other long-term retail accounts like Costco. One-off random signups either get an alias on my domain or a random one from SimpleLogin if I don’t care about maintaining access to the account.
I just started doing this a few weeks ago so I might change my strategy if it becomes annoying to maintain, but I like it right now.
