SaneBox
A privacy-conscious email filtering tool that learns which senders matter to you and automatically moves low-priority messages out of your inbox, using mostly message headers rather than full content.
Visit websiteWhat it does
SaneBox is a filtering and prioritization tool that sits on top of an existing Gmail, Outlook, or other IMAP email account and learns which senders you actually engage with. Messages from senders you rarely open get automatically routed to a SaneLater folder for batch review, while the rest of your inbox stays focused on what you’re likely to act on.
Unlike most other tools in this category, SaneBox doesn’t draft replies, summarize threads, or take meeting notes — it does one job, inbox triage, and does it with a privacy model built around not storing full message content. That makes it a good fit for people who want less inbox clutter without adopting a new AI writing assistant or handing message content to a third-party service.
Ideal users
- Anyone who wants inbox decluttering without switching email clients or exposing message content to a third party
- People who get a high volume of low-priority mail (newsletters, notifications, CC threads) and want it filtered automatically
- Budget-conscious users who want a cheap, narrowly focused tool rather than a full AI drafting/triage suite
Who should avoid it
- You want AI-drafted replies or meeting notes — SaneBox is a filtering tool, not a writing or notetaking assistant; see Fyxer or Superhuman
- You need a free option — SaneBox has no permanent free tier, only a 14-day trial
- You want a completely reimagined AI-native interface — SaneBox stays inside your existing Gmail/Outlook client
Key features
- SaneLater folder automatically collects low-priority email based on your past engagement patterns
- SaneBlackHole permanently filters out unwanted senders with a single drag-and-drop action
- Works via IMAP inside your existing Gmail or Outlook interface — no new client to learn
- SaneReminders and SaneSnooze for follow-up and deferred handling
- SaneAttachments to offload large attachments automatically
Pros / Cons
Pros
- Distinctive privacy model — SaneBox does not download or store full email bodies on its servers for its core filtering features, relying mainly on headers (sender, subject, timing)
- Works inside your existing email client rather than requiring a switch
- Low starting price relative to full AI email assistants
Cons
- No AI drafting, summarization, or meeting notes — narrowly focused on filtering and prioritization
- Lower-tier plans limit the number of connected email accounts and available features
- No permanent free plan, only a 14-day trial
Pricing
Paid — $7/month (Snack tier, standard monthly billing)
SaneBox is sold across three tiers by email-account count and feature set: Snack ($7/month, 1 account), Lunch ($12/month, 2 accounts plus a choice of additional features), and Dinner ($36/month, 4 accounts, full feature set). Annual prepay lowers each to roughly $59/$99/$299 per year, with further discounts for multi-year prepay, and a 14-day free trial is available. These figures are cross-checked across multiple independent pricing trackers as of July 2026; SaneBox's own pricing page is JavaScript-rendered and couldn't be directly fetched to confirm the exact current numbers, so double-check sanebox.com/pricing before finalizing.
Typical workflows
- A professional with a high-volume inbox connects SaneBox via IMAP, lets it learn which senders they consistently open versus ignore, and checks the SaneLater folder once a day instead of processing every message as it arrives.
Integrations
- Gmail and Google Workspace
- Microsoft Outlook / Microsoft 365
- Any IMAP-compatible email provider
Privacy & security notes
SaneBox states that email bodies are not downloaded to or stored on its servers for its core filtering features, and that filtering decisions are based primarily on headers such as sender, subject line, and timing rather than message content; a small number of features (SaneReminders, SaneAttachments, some SaneSnooze functions) do access content. Per SaneBox's own security documentation, data is encrypted with bank-grade security, account credentials are stored using public-key cryptography with keys held in hardware security modules, and processing servers accept no direct public-internet connections; SaneBox also states it removes email-activity logs older than 30 days and purges data from inactive accounts after 90 days.
Frequently asked questions
Does SaneBox read the content of my emails?
For its main filtering features, SaneBox says it relies mainly on email headers (sender, subject, timing) rather than downloading full message content to its servers. A few specific features, like SaneReminders and SaneAttachments, do involve content access — check SaneBox's current privacy documentation for specifics before connecting a sensitive inbox.
Does SaneBox replace Gmail or Outlook?
No. SaneBox works via IMAP inside your existing email client, moving messages between folders like SaneLater automatically. You keep using Gmail, Outlook, or another IMAP client as your interface.
Is SaneBox an AI writing tool like Superhuman or Fyxer?
No. SaneBox focuses narrowly on filtering and prioritizing incoming email — it does not draft replies or take meeting notes. For AI drafting, pair it with a separate tool or use one of the AI-native clients in this category instead.
