Why Do You Need a Nine Email Alternative?

(Hint: Instability 🌀)

nine email alternatives

Nine Email & Calendar, developed by a Korean company called 9Folders Inc., is an email application designed for Android and iOS platforms. The Nine Email & Calendar app offers seamless integration and synchronization with Microsoft Exchange, making it an ideal choice for business users who rely on Exchange for email, calendars, and contacts. 

Although Nine Email is a reliable email app with handy features and a clean interface, some users realize that it doesn’t fulfill their needs. 

Here are a few reasons why you may need a Nine Mail alternative:

  • Nine doesn’t have AI capabilities: Although Nine Mail offers some pretty email management features, it lacks AI capabilities that other email clients already provide. 
  • Nine Calendar doesn’t integrate well with Gmail: Although Nine Email works with and synchronizes well with all IMAP servers (such as Gmail), the other apps offered by Nine, such as the calendar, contacts, and notes, only work on accounts supporting ActiveSync. 
  • Nine can be slow and unstable: Some users have reported that Nine Mail can be unstable and slow, leading to regular reinstallations and issues with email synchronization, calendar appointments, and contacts. 
  • Nine works only on mobile: If you’re looking for a web-based or desktop-based email client, Nine isn’t suitable for you since it’s designed to work only on mobile devices with Android or iOS operating systems.
