Best Email Clients For Linux [2021]

Most of us access our emails from the web browser. While web browsers may be a common way of accessing emails but not quick and efficient. Email clients for Linux easily sync email accounts with the system and notify users of any new email.

Email clients can add multiple email accounts and keep users informed about every new email. If needed, supports plugin-ins for adding any missing feature. Email clients can also read feeds from your favorite blogs.

In this article, I will review some of the best email clients for Linux. Even though this list contains 6 email clients, many of them still are out of the list. Let me know if you use any email client that you think should be on this list.

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 plugins or use the plugins already developed by the email client or community.

Best Linux Email Clients

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

Most of the email clients I am going to mention are either available in most Linux distributions repositories or available as a snap and flatpak. In case 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.

Users can add multiple accounts in Thunderbird. No matter what email provider you use, it can easily add it.

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.

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 how to create plugins but 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.

ElectroMail is an unofficial email client for ProtonMail.

  • So you actually miss the only really good one - Kmail... Impressive! ;-)

    But seriously, I must admit I only tried Thunderbird a few years ago - it was awfully slow and inflexible. KMail eats a lot of memory but at least then it's fast and doesn't block just because you check for mail... And the most important part is that the navigation is top-notch.. You can read all your mails by just hitting space, which will scroll through the message itself, go to the next unread, scroll, next unread... It is very configurable and sure, there's a variety of add-ins.
