Linux is an open-sourced operating system whose popularity is on a constant rise. Although web-based emails are the trend as you can easily access them from a web browser, many users prefer an email client. For each platform, there are different applications, such as on Windows; there are clients like Thunderbird and Microsoft outlook. On iOS and Android, there are apps such as K-9 Mail and Nine. The main question that arises is the best email client for Linux?

Although there have been quite a few releases on Linux over the years, only a handful of email clients have offered comparable features to windows and others. However, one major benefit is that most of the best email clients for Linux are free. Thus you can try them conveniently.

However, the major concern remains as to how you can find the best email clients for Linux. This article will create a list of the best email clients for Linux; whether you seek a GUI (Graphical user interface) email client or the command line one, you will find something on our list.

Best Email Clients for Linux


Thunderbird is one of the best email clients for Linux, and it’s extremely popular among users. The app provides plenty of benefits, making it an excellent choice for a wide user base. The app is both free and open-sourced, and it was initially modeled to suit the Mozilla Firefox internet browser. You can perceive the idea from its tabbed email interface, which lets you keep various emails open simultaneously for quicker reference.

For users that are recently making a shift from Windows, Thunderbird would be easy to use as it offers almost a similar user experience and interface. Furthermore, it also comes with strong theme support and ships with the light and dark themes as the standard ones.

One significant feature of Thunderbird is that it offers a quick filter toolbar, an advanced search tool designed to help find particular email groups. Thunderbird offers a tool with a neat timeline graph that demonstrates the number of emails you’ve received over a particular period. It also lets you arrange the incoming emails from different accounts into the smart folders using filters. Another notable feature is the online storage providers, which instead of attaching a large media file to the email, upload the file on the storage and share the link.

Thunderbird also offers more than 1500 add-ons that help you modify or change the functionality of the email client to fit your requirements.

If you are a GNOME desktop user searching for the best email client for Linux, Evolution is an excellent choice. It is an open-sourced email client that GNOME designs; however, users of other distros can also benefit from it.

With the simple wizard, you can easily set up Evolution with other online services such as Gmail within seconds. You can also use Evolution with other proprietary email clients, including Microsoft exchange, Kolab, Novell GroupWise, LDAP, WebDAV, etc. However, a significant benefit of Evolution is that it offers more features than a regular email client. You can also create task lists and manage a calendar, contact list, and memos. You can use all these features combined to benefit from the email accounts such as Outlook and Gmail. It also offers an RSS plugin for aggregating Atom feeds and RSS.

For the KDE-based Linux distros, KMail is the best email client for Linux, and it’s also the default choice. It means that it offers excellent integration with the KDE desktop environments and other applications, adding to the functionality and benefits. For instance, receiving a meeting invitation over the email client will be detected automatically and sent to the KOrganizer calendar. At the same time, KAddressBook handles the auto-completing of the email address.


KMail offers a template system that allows you to automate the writing. It has a powerful filter system as well as mailing list management. A huge benefit is that KMail can automatically detect hotel reservations or pending flights and feed them into the KOrganizer. Additionally, it will let you pair KMail with notable spam checkers such as SpamAssassin and Bogofilter.

There is one downside to KMail: it doesn’t support Microsoft Exchange, thus limiting its usefulness in certain environments. However, it does provide end-to-end encryption by the integral OpenPGP.

Nearly all of the best email clients for Linux that we have mentioned on our list require a comparatively modern machine to operate successfully. However, if you are working on an older piece of hardware, then a lightweight email client such as Geary is a great choice. It is an open-sourced software part of the GNOME desktop environment project. It intends to provide quick and simple functionality primarily for the GNOME desktop, but you can also download and use it for others.

Although Geary may not provide extra features such as a calendar and smart contact management, the email search options are all rudimentary. Although the feature is in development, it doesn’t support labels either. Apart from it, Geary provides a smart and attractive interface that gives a modern appearance better than some more popular choices like Evolution.

Geary aims to keep the email simple as it doesn’t consume many resources. If you like using a GUI email client but you want a choice without all the extra address books and calendars, then Geary should be a priority.

Sylpheed is another lightweight app, and it’s a versatile choice that you will most likely find on all platforms.

Some email clients will naturally crawl and become slower if your inbox is constantly bombarded with thousands of emails. Sylpheed, however, works brilliantly despite the loaded. It rarely crashes, even if you are managing thousands of emails simultaneously.

It also offers certain other features, including automatic junk mail control, email filtering, supporting, and encryption of the emails through GnuPG. You can also use email filters to get particular types of emails and external commands which will assist you in automating the workflow.
