@deirdrebeth @Matt_the_bad_writer If you're interested in user opinions: I've been using #ProtonMail for a couple years, ish, and it works reasonably well for the most part, but a lot of UI actions feel a bit slow (probably necessary to some extent because of the E2E encryption), and there are some, like swipe-to-archive, that behave in unusual ways. But my main gripes are:
- Filtering is *painfully* slow. Any change to filters takes on the order of an hour to take effect.
- Proton vastly restricts the ability to use different email addresses at a custom domain. I can set up a catch-all address to receive anything sent to my domain, but sending mail from any new address requires a settings change, and I'm limited to 16 active sending addresses.
There was also a thing some months ago about some inappropriate political statements made by Proton's CEO, and the company has never tried to distance itself from that AFAIK.
So I'm not exactly displeased with Proton, but I'm keeping my eyes open for alternatives.
