SaneBox is an AI-powered email management service designed to help individuals and teams reduce inbox clutter and spend less time handling messages. It works with major email providers, including Gmail, Microsoft 365, Apple iCloud, Yahoo! Mail, and Fastmail, as well as IMAP, Microsoft Exchange, and ActiveSync accounts. The service operates with existing email clients across desktop and mobile, without requiring a download or manual setup.

Using algorithms and machine learning, SaneBox sorts incoming email by importance and offers tools to make inbox management easier. Daily Digest summarizes less important messages, while BlackHole helps remove unwanted senders. Users can snooze emails until a more suitable time and set reminders to follow up when someone has not replied or to revisit a message later. SaneBox offers several paid plans, each with different features and account limits, and provides a seven-day free trial. The company also offers discounts for educational, nonprofit, and government organizations. SaneBox says it does not sell or share user information and limits the email data it stores.
