Fastmail
No-fuss email service provider that respects me and my privacy. At $50 per year, I can use it with all the domains I own, and create hundreds of aliases as I need.
Fastmail has personalized spam filtering that actually works. You can set up forwarding and filing rules based on a myriad of factors. You can also go crazy with Sieve Script if that’s what you want. It works with your email clients via IMAP or JMAP, and supports Apple Mail push.
