I think gerbils who use lava mail solve my question. I will firstly use that kind of mail which is crypted. But can not find mail web interface at their site. Does it use Magma interface in my OS system (I think so)?
Have to download Magma? Or wait web interface for use lava mail? Do you use before?
These questions a bit boring but that is my first steps
I haven't used Lavabit's email service, but I do have an account on Protonmail, which is encrypted and might do what you want. They've got apps on Android and iOS.
Depending on your threat model/paranoia level, Protonmail's also reachable over their Tor onionsite: https://protonirockerxow.onion/
