What's the best Android app for managing a cluttered personal email inbox?

Yahoo Mail is a veteran option for personal email management, particularly for users dealing with an overstuffed inbox. The app’s primary strength is its organizational system, which automatically splits incoming messages into ‘Primary’ for important emails and ‘Other’ for subscriptions and promotions. For anyone who receives a high volume of newsletters or promotional emails, this built-in triage can significantly reduce clutter at a glance. The app also integrates a powerful universal search that can find attachments, contacts, and specific email content quickly, which is useful for digging up old receipts or conversations. A notable feature for real-world use is the ability to swipe messages to archive, delete, or schedule for later, allowing for fast inbox processing during a commute. However, user feedback consistently points to a significant weakness: spam filtering. Reviews indicate that unwanted emails sometimes bypass the spam block, landing in the main inbox. Additionally, some long-term users have noted difficulty switching the default view back from ‘Primary’ to ‘All’ mail, which can be a minor frustration. Despite these imperfections, the app provides 1 TB of free storage, removing the need to constantly delete old emails, and supports multiple account integration, making it a practical hub for personal correspondence.
