Great replacement of WhatsApp by using a decentralized technology backbone that is already in place: email. However the app still need to mature in development. For example: if someone sends multiple messages after each other within a short amount of time (just like any IM some people unfortunately sends a message for every line ..) for some reason at the receivers end the messages do not appear in the correct order. can't tell if this is caused by the order of the emails receiving in the inbox

Love the simplicity and the ability to switch between multiple accounts. This could be a very good alternative to whatsapp/signal/telegram but in my personal opinion it's better because it uses your emails mail servers instead of a centralized server like the other mentioned apps. It's also cool that if the other person doesn't have Delta Chat he/she wil still receive the message in there emails inbox. It's not a perfect app but I comes close to it.

I don't receive notifications a while after closing the app. I have to keep it open for notifications to work. But all in all it's a really good app, doesn't require anything! All you need is a name to go with. Although I do have some suggestions or requests. 1. Will you make it possible to send images from google photos app directly through delta? 2. Will calls ever be implemented?
