SaneBox
Server-side email triage that never reads your message body
About
SaneBox is an email management service that works on top of your existing inbox instead of replacing it. Running server-side over IMAP, it learns which senders you actually engage with and routes the rest into a SaneLater folder, silences chronic senders with SaneBlackHole, snoozes mail with SaneRemindMe, and sends a daily digest of what it filtered. Its defining trait is privacy: it classifies on sender and engagement metadata and never reads or indexes email body text, which suits security-conscious teams. Be clear about what it is not: it will not summarize threads or draft replies — it is a sorting engine, not a writing assistant — and there is no free plan, with tiers from around $7 to $36 per month.
What it can do
- SaneLater: automatic routing of low-priority mail out of the inbox
- SaneBlackHole: one-click permanent sender blocking
- SaneNoReplies and reminders for follow-up tracking
- SaneDigest: daily summary of filtered mail
- Header-only processing; never reads message bodies
Setup
- Sign up at sanebox.com and connect your email account over IMAP.
- SaneBox creates server-side folders (SaneLater, SaneBlackHole, etc.).
- Drag emails between folders for a week to train its classification.
- Review the daily digest to catch anything misfiled.
Prerequisites
An email account with IMAP or Exchange Web Services support.
