Cleanbox vs SaneBox vs Clean Email: Inbox Management Tools Compared
If your inbox is overwhelming, three tools take fundamentally different approaches to fixing it. Cleanbox filters email before delivery. SaneBox sorts email after delivery. Clean Email helps you bulk-clean what is already there. Understanding the differences helps you pick the right one — or combine them.

Cleanbox: the gatekeeper
Cleanbox sits between the internet and your inbox. Emails are scanned, scored, and filtered before they reach your mailbox. Spam is rejected. Contacts are categorized. Shield rules limit who can email you and when.
Best for: People who want unwanted email to never arrive in the first place. Businesses that need relay protection for existing addresses. Users who want per-alias spam control and contact intelligence.
Limitation: Aliases are receive-only — you cannot reply from them. Does not organize email that is already in your inbox.
SaneBox: the sorter
SaneBox connects to your existing email account and uses AI to sort incoming messages into folders. Important emails stay in your inbox. Everything else goes to @SaneLater, @SaneNews, or @SaneBlackHole. It learns from your behavior — drag an email to @SaneBlackHole and you will never see that sender again.
Best for: People who want AI-driven inbox prioritization without changing their email workflow. Works alongside your existing provider with zero setup friction.
Limitation: Email still arrives — it is just moved to folders. No spam scoring, no virus scanning, no MX-level protection. Does not prevent spam from being downloaded to your account.
Clean Email: the cleaner
Clean Email connects to your mailbox and helps you bulk-manage existing emails. Group by sender, unsubscribe from newsletters, auto-clean old promotions, set rules for future messages. It is primarily a cleanup and maintenance tool.
Best for: People with years of accumulated email clutter who need a mass cleanup. Good for ongoing maintenance with auto-clean rules.
Limitation: Reactive, not proactive. Does not filter email before delivery. No aliases, no custom domains, no MX relay.
Can you combine them?
Yes, and many users do:
- Cleanbox + SaneBox — Cleanbox filters spam before delivery, SaneBox sorts the surviving email by importance. Belt and suspenders.
- Cleanbox + Clean Email — Cleanbox handles new email, Clean Email helps clean up the backlog from before you started using Cleanbox.
If you only pick one, the question is whether your problem is too much spam (Cleanbox), too much noise (SaneBox), or too much accumulated clutter (Clean Email).
