SaneBox is aI email triage that works on top of any provider (Gmail, Outlook, IMAP) — filtering low-priority mail into a SaneLater folder so the inbox holds only what needs attention. It's a strong pick when: founders and leads drowning in notifications who won't switch email clients. But it isn't right for everyone — the main reason to look elsewhere: triage only — it won't write or answer email. For AI drafting you'd pair it with something else.
The alternatives worth considering
- Superhuman (client)
- Shortwave
- Gmail filters (free, manual)
- Clean Email
How to choose
Start from the limitation above. If it doesn't apply to you, SaneBox is likely the right call — no new client to adopt: it re-sorts your existing inbox, which is why it sticks where email apps get abandoned. If it does apply, shortlist two of the alternatives and run both free tiers/trials against one real task before paying for either.
