I've used DeltaChat for about 7 years. I even managed to get a few family and friends to install it for a while, so we the built-in AutoCrypt would encrypt our emails. But none of them stuck with it.
Until recently DC continued to be a great mobile app for my personal email account. However, the devs are slowly moving away from supporting my use case, in favour of DC being a client for dedicated ChatMail servers. Which leaves me scratching my head as to its utility.
