Our detailed descriptions of the best email clients for Windows will surely excite many of you fans of all things email applications. We made sure to include all the info you need to decide on the best client for your needs. So let's not tarry!

Note: What is an email client? If you aren't familiar with this topic, we suggest learning the basics first.


1. Microsoft Outlook (Best email client for Windows overall)

Microsoft Outlook Email Client for Windows

Why We Chose It:

Unsurprisingly, a Microsoft email app is our number one email client for this operating system, as both come from the same parent company. For many reasons, we can say that Microsoft Outlook is the best email client for Windows overall.

It's a sophisticated yet user-friendly platform, especially when paired with Microsoft 365—a suite with numerous productivity apps like Word, Excel, PowerPoint, and SharePoint. Outlook is the one-stop solution for businesses seeking a reliable email client.

Microsoft's New Outlook for Windows will replace Windows Mail in 2024. This free app maintains the essential features of Outlook while sporting a modern and simplified design. It includes familiar elements like the Focused Inbox, My Day view, Outlook's signature calendar, and contact management features.

However, after further exploration, we concluded the free version has limitations. It lacks support for traditional COM add-ins and doesn't yet have offline support.

During testing, it only supported Microsoft, Google, and Yahoo accounts. While free, you may encounter promoted messages in your inbox. If the free version falls short, consider a paid Microsoft 365 subscription for the full range of Outlook features.

Both versions allow customization with various themes and extensive options for organizing the user interface. Additionally, both versions offer pre-made templates, built-in dictation, read-aloud text, and rules for email management.

Paid Outlook customers can access hundreds of third-party integrations called Add-Ins, enhancing the user experience.


  • Seamless integration with other Microsoft apps in Microsoft 365.

  • End-to-end encryption, phishing scam, virus, and malware scanning.

  • Backup and recovery features with Microsoft OneDrive.

  • Mobile-friendly interface, including a lite version for low-resource phones.

  • Compatibility with other email providers like Gmail.


  • The free mail account includes ads.

  • Lacks end-to-end encryption.

  • Doesn't scan attachments.


  • Outlook has a free email client and calendar tool

  • Microsoft 365 Personal costs $69.99 per year

  • Microsoft 365 Family costs $99.99 per year

2. Thunderbird (Top open source email client)

Mozilla Thunderbird Email Client for Windows

Why We Chose It:

The Thunderbird email client is brought to us by Mozilla, which also makes the popular web browser known as Firefox. Thunderbird is a top open-source Windows mail client if you want to sync multiple accounts.

Thunderbird offers customizable local email storage, backup scheduling, and server management with added security features like end-to-end encryption. Being open source, it comes with various free add-ons to enhance user experience.

Regarding the user interface, we determined that Thunderbird's design may not be the most modern for Windows 11, resembling Mozilla's Firefox.

However, despite lacking style points, it compensates with customization options, accessible through the top-right hamburger menu. Various themes, such as Suave and Dark Fox, provide different inbox looks.

During testing, Thunderbird showed mixed results in sending and receiving speeds. While outbound Gmail emails were nearly instant, receiving emails in the Thunderbird client varied.

Extensions like Smart Templates and Quicktext, available through Tools > Add-on Options, enhance Thunderbird's capabilities for efficient email management.


  • Accessible and user-friendly webmail, especially for managing multiple email accounts in a unified inbox.

  • Mail setup wizard simplifies IMAP, SMTP, and SSL/TLS configurations.

  • Advanced features include tabbed email, content blocking, message archive, do not track, and collaboration tools.

  • Add-on manager for further customization, including custom skins and smart folders.

  • Excellent security features, including private emails and phishing protection.

  • Open-source email client, preferred by many over proprietary software.


  • While a top email app for Windows, Thunderbird doesn't rank as well for Mac OS or iPhone users.


  • Mozilla Thunderbird is a free and open-source email client

You can choose your preferred layout, customize common actions, and easily manage previous emails with a convenient right-click feature. Fine-tuning the UI is simple through Settings > Appearance > Themes, allowing changes to buttons, progress bars, links, and more.

The sidebar provides quick access to contact details, past conversations, agenda, and calendar, all customizable. eM Client supports video meeting integrations with various providers, chat integration with XMPP/Jabber, and cloud hosting for attachments using Dropbox, Google Drive, OneDrive, and others.

Spark is available for iOS, macOS, and Android. With Smart Inbox, this mail app intelligently categorizes emails into personal ones, newsletters, and notifications, making it easier to focus on essential messages.
