Delta Chat, have a chat conversation with your email address

about delta chat

In the next article we are going to take a look at Delta Chat. This is an application that it will allow us to convert our existing email account into a chat application. With it we can send messages to anyone, from our existing email contacts. Delta Chat is from Open Source and Free software.

This is an application like Telegram or Whatsapp, but without the tracking or central control. Delta Chat does not need a phone number. Take a look at their statement of compliance with GDPR. This program does not have its own servers but uses the most massive and diverse free messaging system that exists, which is the existing email server network. The program it will allow us to chat with whoever we want, previously knowing their email address. Also, it is not necessary that the contact with whom we want to chat has DeltaChat installed.

Install Delta Chat on Ubuntu

As a .DEB package

Delta Chat has a DEB package available for installation in the project download page. If you prefer to use the terminal (Ctrl + Alt + T) instead of the browser to obtain the latest version published today, you will only need to use the wget command in it as follows:

download .deb file


Once the download of the .DEB package to our system is finished, We will only need to use the following command to install the application. Installation will be quick and should resolve any dependency issues automatically.

install deb package

sudo apt install ./deltachat-desktop_1.14.1_amd64.deb

After the installation, we can find the program launcher in our team.

For remove this installed program as .deb packageAll you have to do is open a terminal (Ctrl + Alt + T) and use the command:

uninstall deb delta chat

sudo apt remove deltachat-desktop

Like Flatpak

To perform this installation we must have the possibility of using this technology in our equipment. If you still don’t have it enabled on your Ubuntu system, you can follow the guide that a colleague wrote in this blog a while ago.

Once this technology is enabled in our equipment, we can install the program as flatpak package in our system, using the command in the terminal (Ctrl + Alt + T):

install application as flatpak

flatpak install flathub

When the installation is finished, we can launch the program by typing in the same terminal:

flatpak run


For remove this program installed as flatpak, in a terminal (Ctrl + Alt + T) we only need to execute the command:

uninstall flatpak deltachat

flatpak uninstall

As AppImage

For download this file from Delta Chat, in a terminal (Ctrl + Alt + T) we will only have to use the following command:

download delta chat as appimage


Then we will have to give execution permissions to the file that we have just downloaded. We will do this using the following command in the same terminal:

sudo chmod u+x DeltaChat-1.14.1.AppImage

Now we can run the program by double clicking on the file, or by using the command:


Set up and use Delta Chat

Once the program is launched, on the first screen that we will see, we will have to select the button ‘Login to your server’. This button will allow us to log into our email account.

On the next screen we will have to enter our email address and password. Please note that we must take additional steps to ensure that Delta Chat works if we use Gmail. We may need to create an app-specific password, or enable login for less secure apps.

After entering our user account information, we should now be able to log into Delta Chat with our existing email account.

Application preferences

The use of this application is very similar to any other chat application, and also the interface makes it very easy. To send a message to anyone, we first need find the 3-dot menu in the upper right corner and click with the mouse.

open new chat

Then we will have to look for the button ‘New chat‘and select it. This will bring up a pop-up menu. That’s where we can find the email address of the person we want to talk to. This will create a new window.

message from delta chat

In this new window, we can now write the messages in the text box, then we just have to click send. Delta Chat will deliver the message as an email, but in the app it will look like a message.

This is how we can talk to the person to whom we sent the message, without having to download the application. As if it responds to the email, we will see this response in the application as a new chat message.
