"Cypht is not your father's webmail. Unless you are one of my daughters, in which case it is your father's webmail. Cypht is like a news reader, but for E-mail."

The design is so ugly, though...
As a marketer it kills me the amount of cool projects whose adoption may be hurt by a lack of a couple extra screenshots.

Was about to ask about support for 2-factor authentication, then saw this:
Support for 2 factor authentication with any TOTP compatible

Many mainstream (read: Apple/Microsoft) mail clients need plugins (which eg on iOS aren't an option) for PGP Mail, but S/MIME is handled out of the box.
I'm not comfortable uploading my private key to a webmail server, even when its my own server
Yes, but not on the server. The key is typically stored encrypted in the browser storage. Never hits the server.
But there is still the problem where the server could send "bad" javascript which copies the key and uploads to the server.
However, if it's my server and I'm running the webmail, I might be ok with that. And if the server is being run by somebody I trust, I might still be ok with making that decision.
And even if I don't want to add my own private key, it would still be nice if the webmail could verify messages signed by other people. There's nothing risky about that.
