nice! if you want to join a small ArcaneChat community group: https://i.delta.chat/#6CBFF8FFD505C0FDEA20A66674F2916EA8FBEE99=&a=invitebot%40nine.testrun.org&g=ArcaneChat+Community&x=3KvvQZfzU4t-9u5s0PF3USGp&i=AQKH9_8x0R0&s=dbGW9xOhRQX

preferably join with an anonymous arcanechat.me profile, not with your main account ;)

It is for encrypted email only, its possible if the other people use some client that supports encryption, if you question is “can the email provider be used to send and receive unsecure unencrypted email that the server would have access to and read all my conversations?” the answer is no, the app can be used with such unsecure providers but arcanechat.me server is focused on security and no unencrypted email/data is ever stored on the server

It is an email provider but for encrypted email and optimized for speed and security, to use for chatting, the app looks like WhatsApp etc but every message is just an encrypted email

If what you want is encrypted email, and see it in the form of a chat, take a look at ArcaneChat
