My email provider will auto-generate aliases with no limit, and I also subscribe to Mozilla Firefox Relay, which allows me to invent email addresses on the fly and have them relay emails to my inbox. The advantage of the Firefox Relay is that it isn’t tied to the email provider so if I switch provider the aliases can still work.
No, I’m on Fastmail. It’s full-featured and has a slick web UI, but it’s not as good for privacy as Tuta, Proton, etc. Also, although Fastmail is Australian they apparently host their servers in the USA.
