What Is SaneBox?
Email was supposed to make communication easier. Instead, most inboxes have become overwhelming streams of newsletters, notifications, promotional messages, and low-priority requests mixed with genuinely important communication. SaneBox is a cloud-based email assistant that quietly organizes this chaos by learning your behavior and automatically sorting messages without you lifting a finger.
The service connects to virtually any email provider—Gmail, Outlook, Exchange, custom domains—via IMAP, Exchange, or ActiveSync protocols. After a quick two-minute setup, SaneBox analyzes your email patterns: who you respond to quickly, whose messages sit unread, which senders you consistently archive. Using this analysis, it shuffles non-urgent mail into separate folders while keeping genuinely important messages in your primary inbox.
Think of it as noise-canceling headphones for email. The newsletters, automated notifications, and "reply-all" chains that clutter your attention get filtered automatically, while messages from bosses, clients, and close contacts remain front and center.

Key Features Explained
SaneLater: Intelligent Auto-Filtering
The core feature is deceptively simple. Messages that can wait—newsletters, promotional emails, social notifications, low-priority requests—automatically land in @SaneLater instead of your primary inbox. You see fewer interruptions immediately.
The magic is in the learning. SaneBox doesn't rely on simple rules; it analyzes your behavior to understand importance. If you always open emails from a particular sender quickly, they stay in your inbox. If you consistently ignore certain types of messages, they move to SaneLater.
When SaneBox occasionally mislabels something, drag it back to your inbox. The system learns instantly and won't make the same mistake twice. Over time, accuracy improves as SaneBox understands your preferences better.
SaneBlackHole: Permanent Unsubscribe
Traditional unsubscribe links often don't work, take days to process, or result in more email from related lists. SaneBlackHole offers a permanent solution: drag any email into @SaneBlackHole, and future messages from that sender bypass your inbox entirely, self-deleting after 7 days.
No clicking, no waiting, no hoping the sender actually respects your request. One drag gesture eliminates a sender forever—the email equivalent of throwing junk mail directly into the trash without ever seeing it.
SaneReminders: Follow-Up Automation
Important emails often require follow-up that never happens. Someone says they'll respond "next week" and then disappears. SaneReminders solves this without additional apps or manual tracking.
BCC an address like 1.week@sanebox.com when sending an important email. If no reply arrives within a week, the thread resurfaces in your inbox automatically. Send future-dated messages to yourself using addresses like friday@sanebox.com or monday.9am@sanebox.com. Tasks and reminders appear exactly when you need them.
This feature alone replaces dedicated follow-up tracking tools for many users.

SaneSnooze: Defer and Return
Some emails require action but not right now. Moving messages to @SaneTomorrow, @SaneNextWeek, or custom snooze folders removes them temporarily. They return to your inbox at the specified time, ready for attention when you can actually address them.
Optional auto-replies let contacts know when to expect a response—useful for managing expectations without manually writing "I'll get back to you next week" messages.
SaneNoReply: Track Awaited Responses
When you send important emails, tracking who hasn't responded is tedious. SaneNoReply monitors your sent mail and notifies you when expected replies haven't arrived. Follow-ups become practically automatic—you know exactly who owes you a response.
Daily Digest: Visibility Without Clutter
Once daily (or every 4 hours on some plans), SaneBox sends a summary listing everything it moved out of your inbox. Review filtered messages in one glance, approve SaneBox's choices, or correct misclassifications in bulk. You maintain complete visibility and control while enjoying a cleaner inbox.
Real-World Use Cases
Executives and Managers
Leaders receiving hundreds of daily emails use SaneBox to surface only what matters. Automated newsletters, vendor pitches, and routine notifications filter automatically, leaving time for strategic communication.
Salespeople
Sales professionals use SaneReminders to ensure follow-ups happen systematically. BCC the reminder address when sending proposals, and SaneBox resurfaces deals that need attention without manual tracking.
Freelancers and Consultants
Independent professionals juggling multiple clients keep important client communication front and center while newsletter subscriptions and marketing emails get filtered to review later.
Anyone Overwhelmed by Email
If your inbox feels like a fire hose, SaneBox provides immediate relief. The learning algorithm works from day one, and accuracy improves over time with minimal effort.

Tips for Best Results
Train misclassifications immediately: When SaneBox moves something incorrectly, drag it back. The faster you train, the faster accuracy improves.
Use SaneBlackHole aggressively: Every persistent unwanted sender you blackhole reduces future inbox noise permanently.
Set up SaneReminders systematically: Make it a habit to BCC reminder addresses on important outgoing emails.
Review the daily digest: Spending 30 seconds on the digest ensures nothing important slipped through.
Start with Lunch plan: Most users find 6 features and 2 accounts cover their needs.
FAQ
Does SaneBox read my email content?
No. The algorithm uses header metadata only—sender, recipient, timestamps, subject lines. Message bodies are never downloaded, stored, or analyzed. This is a core privacy commitment.
Will it work with Gmail, Outlook, or custom domains?
Yes. SaneBox supports any email provider using IMAP, Exchange, or ActiveSync. This covers virtually all business and personal email services. Only legacy POP-only accounts are unsupported.
What if SaneBox misclassifies something important?
Drag the message back to your inbox. SaneBox learns instantly and will prioritize similar messages in the future. The algorithm improves continuously based on your corrections.
Can I cancel without losing my folders?
Yes. When you cancel, choose to either keep the SaneFolders (they become normal folders) or have SaneBox merge everything back into your inbox. Your email is never held hostage.
Is there a free plan?
No perpetual free tier, but the 14-day trial is fully unrestricted. Referrals earn $5 credits toward extending free access.
Final Verdict
Email chaos steals time, mental bandwidth, and focus that could go toward meaningful work. SaneBox offers a quiet, effective solution: set it up once, train it occasionally, and watch your inbox become manageable without changing email clients or developing new habits.
The privacy-first approach (headers only, never content) and broad compatibility (works with virtually any provider) make it accessible to anyone. SaneReminders and SaneBlackHole add functionality that typically requires separate tools.
If your inbox feels overwhelming, SaneBox might be the simplest productivity upgrade available. The 14-day trial makes it risk-free to test whether it fits your workflow.
