What Is an Email Client and Why Should I Use One?

If you’re like most people, you probably check your email at least once every day. And if you’re someone whose work involves communication with customers, clients, and coworkers, the chances are that you deal with emails all the time.

Even though we spend so much time writing, forwarding, and managing emails, we hardly ever pause for a moment and think about how we could improve our emailing experience. We use clunky web interfaces that are not meant for professional use, we accept outdated applications as if alternatives didn’t exist, and we settle for the default email apps on our mobile devices even though app stores are full of excellent third-party email apps.

Broadly speaking, an email client is a computer program used to access and manage a user’s email. But when we use the term email client in this article, we only mean those email clients that can be installed on a desktop computer or a mobile device—not web-based email clients that are hosted remotely and are accessible only from a web browser.

Desktop email clients have several major advantages over their web-based counterparts. They tend to be much better integrated with the operating system(s) they are designed for, and their superior responsiveness makes them much more suited for handling heavy email loads on a regular basis.

Many email clients make it possible to manage all your emails and contacts from multiple accounts easily in one unified Inbox, and some can even be extended with third-party extensions or integrated with other applications.

3 Best Free Email Clients

These days, there’s no shortage of powerful free email client software applications for all operating systems, including Windows, macOS, Linux, Android, and iOS. Below are 3 of our favorite email clients, each offering its own unique set of features and capabilities.


With its attractive freemium pricing model, elegant design, and support for Gmail, Yahoo,, iCloud, and other IMAP/POP3 email providers, Mailbird has established itself as one of the most praised email clients for Windows. Its features include a unified inbox, app integrations, custom sounds, shortcuts, multi-language support, LinkedIn lookup, email snooze, and much more.

You can get Mailbird Pro for a fraction of its full price if you catch one of many deals that are periodically published on Mailbird’s website throughout the year. But even at its full price of €39, Mailbird is well worth it, and we highly recommend it to all Windows users who want more than the Mail app has to offer.


Thunderbird is a free and open-source cross-platform email client developed by the Mozilla Foundation, the people who are behind the Firefox web browser. It was first released in 2004 and nearly killed off in 2015, when Mozilla Executive Chair Mitchell Baker announced in a company-wide memo that Thunderbird development needs to be uncoupled from Firefox. But Thunderbird is still here, loaded with great features and available in 59 languages.

Thunderbird is one of only a few email clients that support addons and themes alike, making it very easy to customize it whichever way you’d like. For example, the Lighting addon allows you to organize your schedule and life's important events in a calendar that's fully integrated with your Thunderbird email, and the Enigmail addon adds support for OpenPGP message encryption and authentication. Thunderbird is available on all major operating systems, including Windows, Linux, and macOS.


Even though Postbox is a commercial email client for Windows and Mac email client, we’ve decided to include it on this list anyway because you can download a free trial version from its website to see how it works without paying a single dollar. “Clean” is the word that perhaps best describes Postbox and its approach to email management. The application is clearly laid out and logically divided into several sections.
