Is there a good iOS app that helps categorize and prioritize emails automatically?

Microsoft Outlook is a robust email application for iOS that excels in automatically categorizing and prioritizing emails to enhance productivity. Its standout feature, the Focused Inbox, separates critical messages from less urgent ones by learning user behavior over time, which is particularly useful for professionals juggling multiple accounts. The app also includes customizable swipe gestures for quick actions like archiving or scheduling, and it integrates seamlessly with calendars and cloud storage services such as OneDrive, allowing users to view attachments and schedule meetings without leaving the inbox. For real-world scenarios, such as filtering work emails during a busy day or sorting personal subscriptions, Outlook's categorization tools reduce clutter effectively. However, some limitations exist; user reviews indicate that the free version displays ads within the interface, which can be distracting. Additionally, while the app supports various email providers, advanced features like rules and filters are more limited compared to the desktop version. Despite these minor drawbacks, Outlook remains a top choice for its reliability and user-friendly design, catering well to both casual users and business environments where efficient email management is essential.
