SaneBox

Analyzes email headers (sender, subject, etc.) without reading content to predict importance and move emails into Sane folders automatically.

Filters less‑important emails into folders like @SaneLater, @SaneNews, @SaneCC, @SaneBlackHole, configurable per your preferences.

Sends summary of unread emails in Sane folders once daily (or as often as every 1–4 hours during the day).

Tools like @SaneTomorrow, @SaneNextWeek, SaneReminders let you snooze emails until later or remind you if no reply is received.

SaneAttachments moves attachments from emails into cloud storage like Dropbox or Google Drive.

Drag‑and‑drop emails or use training pages, filters by domain or subject to train SaneBox where future emails should go.

Training an email to SaneBlackHole sends all future messages from that sender to Trash safely, akin to unsubscribe but more private.

Works with any email service or client (Gmail, Exchange, Outlook, Fastmail, IMAP, ActiveSync) without downloading software.
