Best Email Clients for Linux

Features at a glance

There are hundreds of email clients available in the open-source world. What should you choose depends on your needs, but for a good email client, it should have at least the following features –

Push notifications

For most users, the basic purpose of using an email client is to keep in sync with the inbox. An email client creates a push notification as it receives a new email.

Calendar & Contacts

A calendar is an important tool for making schedules and helps keep track of important events of life. An email client with a calendar can easily create schedules, mark important days, and even auto-detect dates from incoming emails and add them to your schedule. Just like our phones, email clients can also manage contact lists.

Plug-ins support

Email clients’ functionality can also be extended using plugins. If you are a developer, you can create or use the plugins already developed by the email client or community.

Best Linux Email Clients

Before we dive into the list of best Linux email clients, here are a few things you should know first.

Most of the email clients I will mention are either available in most Linux distributions repositories or available as a snap and flatpak. If an email client is available as a snap or flatpak, you’ll need to install the required package manager on your distribution. Head over to the links in this paragraph for instructions. Don’t worry; it takes a few seconds.


And what can be on top besides Thunderbird, the best open-source email client for Linux? Thunderbird comes pre-installed on most Linux distributions. It is actively developed and recently got a big user interface update.

The email client is developed by Mozilla Foundation, the same company that develops Mozilla Firefox. Thunderbird is a free and open-source email client. It has almost all the features that one needs to stay up-to-date with his email accounts, favorite blogs, manage schedules with calendars and manage contacts list.

For security, thunderbird has PGP support out of the box. Earlier, one had to depend on the additional plugin called Enigmail.

Thunderbird has built-in support for Do Not Track and remote content blocking. No report is sent to the sender when you open up an email.

Add-ons support

Besides having several built-in features such as encryption, privacy tools, address book, and calendar, there are hundreds of add-ons available to extends its functionality.

Thunderbird has been around for a long time. It has great community support, and thousands of plugins allow its users to add almost any feature. Whether you want to improve security & privacy, add language support, or enhance its interface, there are always multiple add-ons for that.

There is an offline mode just in case you want to stop sending/receiving emails. Or download messages for offline usage.

Evolution is a pretty basic email client. It has plugins support, but only a few plugins are available. If you are a developer, you can build your own plugin using the newly designed framework in Evolution 2.32.

Install Evolution

We can easily install evolution from the repositories. Just use the package manager to install it in your Linux distribution.

For Debian or Ubuntu or derivatives Linux distributions –

Other useful features of Mailspring are its built-in mail translator, read receipt, and link tracking.

Its translator can translate your emails from 5 languages into your system language. It supports Spanish, Russian, Chinese (Simplified), French, German, and English.

It can show when a particular sent email was read and also track links inside the email.

Mailspring supports plugins for extending the client’s functionality, but no plugins have been developed yet. Although they have an extensive guide on creating plugins, it’s not what most users would like to do. So we’ll have to wait for plugins.

Mailspring simple and sleek interface is pretty good. There are some pre-installed themes that you can choose from or visit the community page for more themes developed by the community.

How to install Mailspring

Important Note

ProtonMail Logs Activist’s IP Address With Authorities After Swiss Court Order

When I wrote this article, I was aware of the controversies around ProtonMail’s inception. Some claim that ProtonMail was created in MIT under CIA. But, today on September 9, 2021, I got the news that ProtonMail logged IP address of one of its users(activist) and shared it with the authorities after a Swiss Court order.

“Proton must comply with Swiss law. As soon as a crime is committed, privacy protections can be suspended and we’re required by Swiss law to answer requests from Swiss authorities,” ProtonMail CEO, Andy Yen, tweeted.

It is a known pattern used by the authoritarian Governments against activists and journalists. ProtonMail should write on their homepage about the policy that their team will share its users personal information such as IP address with the Government authorities if they get an order from the court.

After this incident, I don’t recommend the use of ProtonMail for activism or journalism. For more information on the case, please read the following article –

Soon, I will replace remove ProtonMail from this list. I may also replace it with another one.

ElectroMail is an unofficial email client for ProtonMail.

Protonmail is an end-to-end encrypted email service developed by Cern and MIT scientists in 2013 in Geneva, Switzerland.

ElectronMail has many advantages over Protonmail’s official web browser email client. First of all, it’s on your system, provides quick notifications of incoming emails through a system tray icon. All the information the email client stores on your computer is encrypted with a master password.

Users can add multiple ProtonMail accounts in ElectronMail and easily switch back-n-forth between their accounts.

ProtonMail already has inbuilt ProtonCalendar, ProtonContacts, and even ProtonVPN service.

So if you use ProtonMail as a primary email provider, then use ElectronMail. It is secure and provides the same user interface as the ProtonMail in-browser email client with some additional features.
