I tried the Windows app with several different accounts and found that it worked quickly and without any problems in all cases. Between the many services and devices you can use in Newton, it's pretty easy to find a combo that'll work for you. And the app supports all the popular email services including Office 365, Outlook, Gmail, Google Apps, iCloud, Exchange, Yahoo and plain old IMAP. The app has plenty of keyboard shortcuts for archiving, snoozing or deleting email, so getting around the interface without a mouse is pretty easy. There's a search bar up top, a sidebar that contains all your folders, and a few buttons to filter just unread messages or starred / flagged emails and that's about it. There aren't multiple panes to distract you you either see a list of your messages or whatever email you happen to be reading or writing. For those who haven't given Newton a shot, it's similar to the departed Mailbox app - it's starkly minimal and puts the focus on whatever message you happen to be reading or composing. I tried out Newton on Windows 10 over the last week, and the good news is that it offers a near-identical experience to the Mac app. With Newton already available on macOS, Android and iOS (not to mention the Apple Watch and Android Wear), it's now one of only a few email apps that works on basically any device.

Today, the company is bringing its app to Windows - it should be available on the Windows Store now. If you're the type of person who jumps between macOS and Windows, Newton (formerly CloudMagic) might be worth a look.

There are plenty of good third-party Windows email apps out there, but not many of them work across all the platforms you might use.
