SaneBox
AI email filtering service that automatically prioritizes your inbox by moving unimportant emails out of sight, supporting Gmail, Outlook, and Apple Mail.
SaneBox is an AI-powered email management service that connects to any IMAP-compatible email account and learns which emails are important to you, automatically moving low-priority messages - newsletters, notifications, and marketing emails - into a SaneLater folder so only actionable messages appear in your main inbox. The system continuously improves its filtering based on how you interact with emails, and provides a daily digest of what it moved so nothing is permanently lost. Founded in 2011, SaneBox serves 200,000+ users and works without requiring a new email client - it layers on top of Gmail, Outlook, Yahoo Mail, and Apple Mail via IMAP. Additional features include SaneNoReplies for tracking unanswered emails and SaneBlackHole for permanently unsubscribing from unwanted senders.
