The application "Delta Chat" .. Chat by e-mail

Unlike the IM application development approach, Delta Chat depends on email addresses and servers. The developers of this app promote the basic idea that everyone has an email address and can be used to chat via the app. Even people who do not use the instant messaging application can access it by email.

Technically, the app is actually a messaging app with a modern chat interface where emoticons and attachments such as photos and videos can be sent without a problem, but technically it's not possible to chat with voice or video.

The application has many security points, provides complete and automatic end-to-end encryption, is an open source application, automatically displays known users and works very fast because it relies on the push-IMAP protocol for synchronization messages.

Early access is available for mobile devices with Google Android, and there is a beta version for Apple mobile devices, desktops, Linux computers and Macs, which the user can now try.
