Yes and no. You can't force chats to be encrypted so you don't know for sure that your message will be. Also you can't use your password protected gpg key.
@michal Even so, your first few messages won't be encrypted.
I use delta chat daily, but I would suggest something else if your fist concern is encryption. Matrix is nice
@yisraeldov I use Matrix, mostly for communities. I just think Delta Chat is more approachable to a normal person 😉
