What Makes a Great Email Program for Windows?
Because there are so many email clients out there, choosing the best email app for Windows 10 can feel overwhelming. Luckily for you, we're here to help you identify what features to look for in mail programs so you can select the best option based on your needs.
When comparing mail apps for Windows 10, you want to make sure you choose an option that is compatible with a variety of email providers, especially if you use a combination of providers for your personal and business email addresses. For example, if you use Gmail for your work mail and Yahoo! for your personal inbox, you may want a program that easily supports both without any effort needed. You should also look for an application that's easy to set up and use, but leaves room for customizations.
Of course, any program that also integrates with other applications you use on a daily basis or offers other perks that can boost your productivity and save you time is always a plus. For example, some of the best free email programs for Windows also offer integrations with Dropbox, Google Calendar, and other common business applications. Having all the tools you need in one place saves you time and helps maximize your productivity, especially if they also offer email apps for Android or iOS in addition to your Windows device.
Top Free Email Programs for Windows 10 and 11
There are literally dozens of email programs out there that help you combine multiple inboxes in one centralized location. However, all of the best email programs listed below have one thing in common: you can use them for free.
When compiling this list, we didn't just look for free email programs — we also looked for programs that are easy to set up, compatible with nearly any email provider, and offered some other features that made it stand out from the pack. While some offer unique tools and integration options, others make it easier to do everything straight from your inbox. In other words, at least one of these free email programs for Windows 10 and 11 will meet your needs — it just depends on what you're looking for.
1. Mailbird - Perfect for App Integration and Putting It All in One Place
Just because email has been around for a very long time doesn’t mean that programs should have a conservative user interface and look as if they were designed for Windows XP. Mailbird is a powerful, beautiful, customizable, and intuitive program that lets you manage multiple accounts at the same time, so there’s just one inbox to check every morning, instead of two, three, or even ten.
It’s available in 17 languages, supports convenient keyboard shortcuts, has snooze and attachment search functionality, and includes unique Mailbird filters. Furthermore, Mailbird integrates with apps like Facebook, Twitter, Whatsapp, Dropbox, Google Calendar, Asana, Todoist, and many others.
Mailbird is a free email app for Windows 10 and 11, however, the free version of Mailbird offers significantly less features than their paid tiers.
In fact, the free version of Mailbird does not support more than one inbox at a time, and it only allows integration with a few other applications. Therefore, to really take full advantage of all that Mailbird has to offer, users must pony up the cash for one of their paid versions.
Mailbird is fairly easy to set up, and mostly walks you through the steps during your first session. However, you can go in and add a new address at any time by going to Menu → Options → Accounts. From there, you can add a new account or make changes to already existing accounts.
Pricing: In addition to its limited free email client version, Mailbird offers a personal version for a one-time fee of $79 (or $3.25/month) and a business version for $399 (or $4.92/month). These versions allow you to hold unlimited email accounts, plus the paid tiers include integration with social media accounts and business applications like Asana.
- Beautiful and highly functional user interface
- Unified inbox that lets you manage emails accounts from a single window
- Affordable price
- Third-party app integrations
- Snooze functionality
- No automation features or bulk email cleanup functionality
2. Mozilla Thunderbird - The Best Free-To-Use Option Out There
If you believe in open source email software and look for new free email clients for Windows 10, Mozilla Thunderbird is a great choice. This open-source cross-platform and free email client, news client, RSS, and chat client is developed by the Mozilla Foundation, and its strategy is modeled after that of the Mozilla Firefox web browser.
Thunderbird lets you manage accounts that use IMAP, SMTP, and SSL/TLS protocols, and it has a whole host of useful extra features to convince you to give it a try. Its one-click address book allows you to quickly and easily add people to your address book, so you never have to look up an address on the internet ever again.
An automatic attachment reminder displays whenever you forget to include an attachment before hitting send. And you can open multiple tabs in the same window to minimize desktop clutter.
Of course, if you're worried about Thunderbird lacking in integrations and add-ons since it's free and open source, then let me put those fears at ease. Believe it or not, Thunderbird offers lots of handy add-ons, not to mention the open source functionality gives developers the opportunity to code their own custom add-ons if you can't find what you need.
To get started with Thunderbird, download the application, then navigate to Tools → Account Settings → Account Actions → Add Mail Account. Once you’ve added all of the addresses you’d like to support within Thunderbird, you can begin testing out all of its other features.

Its developers understand that email is a communication tool that works best when it's integrated with other applications and services.
While you can use eM Client as a stand-alone email program for Windows, it shines the most when you take advantage of its calendar management system that lets you manage your appointments in a beautiful and highly customizable interface, comprehensive contacts with several views and exhaustive fields, and built-in chat functionality for instant communication with friends and colleagues alike.
You can try eM Client for free, but you have to pay for eM Client Pro to unlock all of its features. eM Client is primarily a Windows email program, but there’s also a beta version of eM Client email client for Mac computers, which you can try for free.

6. Claws Mail - A Free Program With Lots of Options for Plugins and Customization

For starters, it can double as an RSS aggregator, so you can use it to automatically check websites for updates.

8. The Bat! - The Best in Terms of Security and Encryption Features
The Bat! is one of the oldest Windows 10 email programs that are still in development. It was first released in 1997, and there are currently two versions of the email software: a Home version and a Professional version.
Both versions of The Bat! are designed from the ground up to protect your messages against unauthorized third parties using multiple encryption streams, including robust end-to-end encryption (E2EE). In addition to encryption, The Bat! also ignores all scripts and executable code included in messages and checks attached file extensions to catch all malware.
The Bat! certainly isn't a sleek-looking email program for Windows 10 and 11, but its clunky user interface isn't nearly as unintuitive as it may appear to be at first. It's just that The Bat! is geared toward more advanced users who are already familiar with most of the features it supports. As a new user, you may feel somewhat lost at first, but we recommend you give it a few days before you give up on it.
Unfortunately, since The Bat! Is a lot more technical than the other programs on this list, you’ll probably want to read over their configuration guide before you get started. However, once you get the hang of it, The Bat! Is fairly easy to set up and use – assuming you don’t let your free trial expire.
Pricing: The Bat! is only free for a limited time (30 days). After that time, you'll have to pay $49.99 for the Home version or $59.99 for the Professional version.
