Delta Chat

Communicate instantly via e-mail

Delta Chat is a project that aims to create a messaging app that is completely compatible to the existing e-mail infrastructure.

So, with Delta Chat you get the ease of well-known messengers with the reach of e-mail. Moreover, you're independent from other companies or services -- as your data are not related to Delta Chat, you won't even add new dependencies here.

Some features at a glance:


  • Secure with automatic end-to-end-encryption, supporting the new Autocrypt standard

  • Fast by the use of Push-IMAP

  • Largest userbase -- receivers not using Delta Chat can be reached as well

  • Compatible -- not only to itself

  • Elegant and simple user interface

  • Distributed system

  • No Spam -- only messages of known users are shown by default

  • Reliable -- safe for professional use

  • Trustworthy -- can even be used for business messages

  • Fully OpenSource and Standards based
