Just use WHOIS protection (which should be free, but whatever).
I’m using Thunderbird. It’s convenient for having multiple inboxes and has a subjectively nice interface without much bloat on it. It has a calendar app which is good for planning too. For email, I have a custom domain+TLD plus an account at purelymail. If purelymail goes dicks up I’m not dead in the water.
You’re making me want to emulate this game.
