Why SaneBox Exists

Modern life runs on email, yet our inboxes keep ballooning. SaneBox steps in as a cloud-side assistant that connects to any IMAP, Exchange or Active Sync account and quietly tidies up while you work. It looks only at header data—who sent the message, how fast you usually reply, and how often you interact—so your content stays private. The goal is simple: give you back the mental focus you lose every time a low-priority notification pops up.

After a two-minute setup, SaneBox starts learning your habits and begins shuffling non-urgent mail out of sight. A daily Digest shows what was moved so you always feel in control. In short, the service acts like noise-canceling headphones for your inbox rather than your ears.

Key Features That Make SaneBox Stand Out

SaneLater – Auto-Filter the Noise

Messages that can wait land in the @SaneLater folder instead of your primary inbox. You skim them when you choose, train mis-files with a quick drag-and-drop, and enjoy fewer dopamine-draining interruptions.

SaneBlackHole – One-Click Unsubscribe Forever

Drag a newsletter or promo into @SaneBlackHole and anything else from that sender will bypass your inbox and self-delete after seven days. It is the email equivalent of tossing junk mail straight into the trash.

SaneReminders – Built-In Follow-Up Superpower

Need a nudge? Blind-copy an address like 1.week@sanebox.com and if no one replies within a week the original thread resurfaces at the top of your inbox. You can also send future-dated messages to yourself such as friday@sanebox.com. This simple trick keeps tasks from falling through the cracks without adding yet another app.

SaneSnooze – Defer and Return to Focus

Move an email into @SaneTomorrow, @SaneNextWeek or a custom snooze folder and it vanishes until the chosen time. Pair that with optional auto-replies so contacts know when to expect a response, and you can finally time-block without guilt.

SaneNoReply – Track Who Owes You

Released this year for iOS, SaneNoReply monitors sent mail and notifies you when someone hasn’t answered, making follow-ups practically automatic.

Daily Digest – A Bird’s-Eye Recap

Once a day—or as often as every four hours for power worriers—a summary email lists everything moved by SaneBox so you can approve or correct its choices in bulk.

Pricing: Simple Plans That Scale With You

SaneBox offers a 14-day free trial on all tiers. After that you have three main options:

  • Snack: Manage one account and pick any two features for $7 per month or $59 per year.
  • Lunch: Two accounts and six features run $12 per month or $99 annually. This is the sweet spot for freelancers and small teams.
  • Dinner: Up to four accounts with every feature unlocked costs $36 monthly or $299 yearly for the full buffet.

Educational, nonprofit and government users qualify for a 25 percent discount, and bi-yearly plans include extra free months to lower the effective rate. You can switch tiers or cancel anytime from the dashboard—no hidden fees.

FAQ

Does SaneBox read the content of my emails?

No. The algorithm scrapes header metadata only; message bodies are never downloaded or stored, preserving your privacy.

Will it work with Gmail, Outlook or my custom domain?

If your provider supports IMAP, Exchange Web Services or Active Sync, the answer is yes. POP-only accounts are the rare exception.

What happens if SaneBox misclassifies something important?

Just move that email back to your inbox. The system instantly learns and will prioritize similar messages in the future.

Can I cancel without losing my folders?

Absolutely. You can remove SaneBox and keep the folders—or let the service merge everything back into your inbox—directly from the dashboard.

Is there a completely free plan?

There is no perpetual free tier, but the 14-day trial is unrestricted and you can earn $5 credits for each friend who signs up through your referral link.

Final Thoughts

Email chaos steals time, momentum and even sleep. By off-loading the grunt work of sorting, deferring and reminding to a silent algorithm, SaneBox gives you back the clarity you need to do real work. If your inbox feels like a fire hose, this might be the simplest productivity upgrade you make in 2025.
