The 5 Best Free Email Clients for Your Desktop PC

4 min readMar 22, 2021


Email goes beyond Gmail and your ISP’s email. While the interfaces offered are sleek, easy to use and function well, some people want a central email client that they can rely on across multiple email providers and operating systems.

Free email software for your desktop opens up a world of possibilities that allow you to use a unique set of features that you won’t find in many online clients.

The top free email software you should know about includes:

1. Clariti

Clariti is a business productivity app that is so much more than just a free email client. Of course, users can configure their existing emails in Clariti to send/receive emails and use it as an email client. But the true value is being able to use Clariti for all your digital communication. Clariti brings your emails, chats, call, to-dos, documents…in one app and automatically links related items in a “Clariti Folder”. Clariti Folders add topic-centric organization to your communications, so you are never lost or waste time searching for information. Some of the key features include:

  • Email, chat, calls, to-do, documents…all in one app
  • Related conversations on the same topic automatically connected and organized in SmartFolders
  • Chat directly from an email — no need to forward emails
  • Create to-do from email or chat to preserve context
  • Audio calls and screen sharing
  • OrbitChat to allow users to connect with others who may not be Clariti users

Clariti is ideal for small and medium businesses to boost team collaboration and drive productivity.

2. Thunderbird

Thunderbird is designed to make email easier, and it does an impeccable job in this department. When you fire up the client, you’ll go through a setup wizard that will help you setup your mail in just a few minutes.

Built into Thunderbird is:

  • One-click address book
  • Attachment reminder
  • Tabbed email
  • Filters and search
  • Auto responder
  • So much more

While Thunderbird may no longer be in development, maintenance updates are still developed to keep it running smoothly. Thunderbird is available for a variety of operating systems, including Linux, Mac and Windows. It’s a free email software that is 100% worth using.

3. Mailbird Personal

Mailbird wins award after award for being an intuitive, beautiful email client that is available for both Mac and Windows. The client allows for multiple account management with a sleek interface that tries its best to optimize cluttered mailboxes. The one main concern with Mailbird is that it’s different than virtually every other mail client. If you’re going from one mail client to another, there’s a lot that won’t feel similar, which can make migration tedious. The interface is minimal and sleek, offering:

  • IMAP and POP syncing
  • Fast indexing and search
  • Support for 3 accounts on the free tier
  • Integration to Dropbox, Google Docs, Evernote and more

If you want a clean, minimalistic email client with a ton of great features, Mailbird is a great option.

4. eM Client

eM Client is an email software on steroids, but there are far more advanced features available on the pro tier than the free tier. The free tier does have a lot of fun, exciting features that you can use to enhance your workflow and boost productivity:

  • Full email client
  • Built-in calendar
  • Task management system

You’ll only be able to connect two of your mailboxes to the platform, so if you need more, one of the other clients or a pro account will offer you more power. The free version supports virtually all mail technologies, including (but not limited to) Exchange, IMAP, Office365, POP3 and SMTP.

5. Mailspring

Mailspring is a way to boost your productivity across Linux, Mac and Windows. Free and pro versions exist, and the free version is definitely worth trying. You’ll be able to unify unlimited email accounts in one box, unsend emails and sync with all of your current email accounts, including:

  • Gmail
  • Office 365
  • iCloud
  • FastMail
  • Yahoo

Layouts and themes are supported. There is even link tracking, read receipts, touch and gesture support, and advanced shortcuts you can use. The product is localized in nine languages, and you’ll be able to use a Gmail-style advanced search feature, too.


Email is a way for businesses to communicate with clients and their own teams. The list of free email software above offers something for everyone, from robust interfaces to advanced features. Download one and give it a try to see if you like it.
