Outlook for Windows

Outlook for Windows is a new email client and personal information manager that replaces the defunct Windows Mail and Calendar apps (which are no longer supported by Microsoft). This default email client app is included in most newer Windows 11 PCs shipped in 2024 and features tight integration with Microsoft 365 apps, AI tools, and a fresh design.

eM Client

eM Client sets itself apart as one of the most customizable email clients available. You can personalize not only the user interface (with a flexible layout and dozens of themes), but also the way the app handles email. Available for Windows, macOS, and most recently, Android and iOS, eM Client is suitable for professional and personal users who want complete control over every aspect of their email experience.
