The mobile version of Microsoft Outlook can trace its roots back to the excellent mobile email app Accompli, which Microsoft bought and used to improve its own email client. As a result, Outlook stands out as a mobile productivity powerhouse, bringing your email, attachments, contacts and calendars into easy reach. 

Outlook's built-in analytic engine automatically surfaces important email (across multiple accounts) based on your communications. Quick swipe controls allow you to easily triage your email. It's a great mobile email app, and works with Exchange, Office 365,, Gmail, Yahoo Mail and iCloud email accounts. Over the years, Microsoft has enhanced the Outlook mobile app with new features, such as Do Not Disturb settings on iOS, which helps keep it at the top of our best email app list.

Outlook is a free download, though a $6.99/month Microsoft 365 subscription adds 1TB of storage and access to all features in the Microsoft Office suite.

Other email clients featured in this list are keen to boost efficiency within an existing system. If you think that’s mere tinkering around the edges, you might like Hey Email’s opinionated alternative.
