help SaneBox FAQ

How does SaneBox integrate with my existing email provider?

SaneBox connects via IMAP/SMTP protocols to your current email provider (Gmail, Outlook, iCloud, Yahoo). It reads email headers and content to categorize messages, then moves low-priority items to your SaneLater folder while leaving your main inbox intact.

Is SaneBox secure and does it read my emails?

SaneBox uses AI to analyze email metadata and content to determine importance. Data is processed on their servers with encryption. Users can enable privacy settings to restrict processing, and you can review which emails are being sorted through your SaneBox dashboard.

Can I customize which emails go to SaneLater?

Yes, you can train SaneBox by dragging emails to different folders or using commands like @SaneLater, @SaneBlackHole, or @SaneNoReplies. The AI learns from your corrections and adjusts future sorting accordingly.

What email providers does SaneBox support?

SaneBox supports major providers including Gmail, Google Workspace, Outlook, Hotmail, Live.com, iCloud, Yahoo, AOL, and any IMAP-compatible email service. It does not support POP3-only accounts or some enterprise email systems.
