I use Proton Mail for my primary domain and then addy.io for redirects to it. It costs $10 a year or something like that and it’s all I actually need.
Replying to emails is as easy as just hitting reply, the only thing that’s slightly harder is sending entirely new email (as in not replying) but even that can either be remembered, or the special email address copied from the addy.io app.
@[email protected] There is a roll of tape. The tape is 100 meters long when unrolled. When rolled up, the outer diameter is 10 cm, and the inner diameter is 5 cm. How thick is the tape?
