What Is an Email Client?
An email client is a software application used to access and manage a user’s email. Most email clients today support multiple email services, including Gmail, Yahoo, Yandex, Outlook, and self-hosted business email systems, and they often make it possible to consolidate emails from all connected addresses into a single, unified view.
Some email clients come only with the most essential features, while others support things like encryption, contact management, out-of-office responses, phishing filtering, image blocking, and others.
When choosing among the best email clients for Windows 10 and 11, you should first decide whether you’re willing to spend any money on an email client or not. Although excellent free Windows 10 email clients are easy to find these days, but paid desktop email clients are often more polished and come with professional support.

Microsoft Outlook is probably the best-known email client in the world. It’s available as part of the Microsoft Office suite, and it can be used as a stand-alone application or with Microsoft Exchange Server and Microsoft SharePoint Server for multiple users in an organization. In the past, Microsoft Outlook had a very bad security reputation, but Microsoft took many corrective steps to fix it, and most security experts agree that Microsoft Office is now on par with other popular desktop email clients.
What makes Microsoft Office one of the best email clients for Windows 10 and 11 is the wide range of features it offers. You can go beyond the basic email tasks and manage your calendar, share meeting times, schedule meetings with colleagues, and get reminders. Microsoft Office is also available on mobile devices, so you can remain productive no matter where you are.
Keep in mind that Microsoft Outlook and Outlook.com are two separate products. The former is one of the best Windows 10 email clients, and the latter is a free email service that looks and files like Microsoft Outlook.

- Does everything you could possibly want it to do

Available for Microsoft Windows and macOS, eM Client is an extremely capable email client that has been in development since 2006. Its target audience are individual users and businesses that have a use for an email client with calendar, tasks, contacts, and chat.
Recently, the developers of eM Client added support for PGP encryption, allowing users to create and import their PGP keys to send encrypted and signed email messages. In addition to PGP encryption, eM Client can also offer live email backups, automatic avatar downloading, improved table editor, basic image editing, and auto-replies for Gmail, among other features.
eM Client is available in two different editions. The free edition is unfortunately very limited because it can’t be used for commercial purposes or display emails from more than two email accounts at once. To unlock all features eM Client has to offer, you have to purchase the Pro edition for $49.95. If you own an older version of eM Client, you can purchase an upgrade license instead of buying the Pro version again.
If there’s something we can criticize about eM Client, it’s the lack of polish that becomes apparent after you use the email client for a while. Some features could be made a lot more intuitive, and there's no excuse for the occasional crashes considering how long eM Client has been in development.
- Exchange functionality
- Dark theme available
- Support for email filters
- Consumes a lot of memory
- Feels unpolished
- Prone to random disconnects
Price: $0 for the Community Edition and $4 a month for the Pro Edition
Rambox isn’t a traditional email client. Instead, it’s a productivity suite whose purpose is to help its users organize their workspace by managing multiple applications from a single place. Like most people, you probably keep one tab open with email, another tab with your messenger app of choice, and one more tab with a calendar. On top of that, you rely on dozens of other online apps that you open and close as you need them. Wouldn’t it be simpler to have them all in one place, accessible with a simple click?
Once you have installed Rambox on your Windows computer, you can simply add all your applications and organize them in groups. At the time of writing, Rambox supports over 600 different applications, including all major email clients, instant messaging and social apps, calendar and scheduling apps, and project management tools.
To take your productivity to the next level, Rambox lets you choose the time you want to receive and prevent notifications so you can work undisturbed when you want to work and handle incoming emails and messages when you have time for them. The Pro version of Rambox, which costs $8 a month, offers a mobile view that allows you to use the mobile version of each app you add to Rambox. This can be helpful when you want to access a certain mobile-only feature from your desktop computer.
- Provides a unique way to organize your workspace
- Easy to usee

There's a noticeable lack of beautifully designed email clients, such as those that are available to macOS users. Fortunately, there's Mailspring, a cross-platform email client that respects modern usability principles and doesn't make simple tasks unnecessarily complicated.
You can use it to access all IMAP/SMTP email services (Gmail, iCloud, Office 365, Outlook.com, Yahoo!, and others) you rely on and conveniently see all emails from them displayed in a single unified inbox. Even if you have tens of thousands of emails, the advanced search feature will help you find the email you're looking for thanks to its support for Gmail-style search queries.
Do you often receive emails in languages you don't speak? With Mailspring, you can translate them with a single click—no need to leave the email client. Mailspring itself has been translated into English, German, French, Spanish, Korean, Japanese, Chinese, Polish, and Brazilian Portuguese.
If you don't like Mailspring's default design, you can easily change it by choosing from a number of professional themes. To gain access to extra features, such as contact and company profiles, read receipts, link tracking, and quick reply templates, you will need the Pro version, which costs $8 a month.

- Touch and gesture support
- Unified inbox
- Requires a Mailspring account

Despite being one of the best email clients for Windows 10 and 11, Claws Mail is nearly 20 years old (first released in 2001). Unlike many other email clients that were around back then, Claws Mail remained in active development as an open source project. Yes, it's spartan design makes it feel outdated, but nobody can question its functionality and reliability.

It supports quick responses, themes, RSS feeds, and plugins, some of which are included in the standard Claws Mail package. The range of available plugins is truly wide, and you can use them to customize Claws Mail exactly to your preferences.

The best thing about Claws Mail, however, is the fact that you can download and use it for free. In fact, you can even customize its code if you wanted to.

- Easy configuration
- Robustness, stability
