SaneBox
Learns which of your emails actually matter and quietly moves the rest into a folder you check on your own schedule, on top of whatever inbox you already use.
What it costs
| Tier | Price | For | Includes |
|---|---|---|---|
| Snack | $9.49/month, $65/year, or $109 for two years | One person who wants the inbox triaged without adding features they won't use. | Core SaneBox filtering across one email account, with the fewer add-on features. |
| Lunch | $15.99/month, $109/year, or $179 for two years | Someone managing more than one inbox, or who wants the fuller feature set. | Everything in Snack across two accounts, plus the additional SaneBox features not included at the lower tier. |

Where it breaks
A Business plan exists for teams but its price isn't published on the same page as the individual tiers, so it isn't listed here.
Works inside your existing email client — Gmail, Outlook, Apple Mail and others — rather than replacing it; there's no separate inbox to check.
First entry in this reference. There is no previous check to compare it against.
SaneBox doesn’t try to be a better inbox. It sits on top of the one you already have and learns, from what you open and ignore, which senders deserve your attention — then quietly reroutes everything else into a folder called SaneLater that you can check once a day, or never.
That’s a different bet than most AI email tools make. There’s no summarising, no drafting replies, no chat interface — just steady, unglamorous filtering that gets better the longer you use it, running in the background without you asking it to do anything each time.
Why the tier names sound like a menu
Snack and Lunch are literally sized to appetite: Snack covers one email account and the core filtering; Lunch adds a second account and the rest of the feature set, things like a digest of what got filtered and reminders on emails you haven’t answered. Pricing drops meaningfully if you commit to a year or two upfront — the monthly rate is close to double the annualized one.
Where it fits against the alternatives
Against a full inbox rebuild like Superhuman, SaneBox is the lower-commitment option: you keep your existing client, your existing habits, and get triage rather than a new interface to learn. If the actual problem is drafting replies faster rather than seeing fewer unimportant ones, this isn’t the tool — it doesn’t write anything, it only sorts.
