@jccIt does work automatically using autocrypt
Autocrypt is a new and open specification for automatic end-to-end email encryption.
Your end-to-end setup is created automatically as needed and you can transfer it between devices with Autocrypt Setup Messages.
Well it works with disroot.org so u can create an account there and then use that for messaging... the USP that your contacts with email can then be contacted via email will still be applicable... I love @Tutanota and am sure there is a good reason why it doesn't work with deltachat but that shouldn't stop you from using both of the lovely solutions....😀
