💡 Key Insight: SaneBox operates only on email metadata — it never reads the actual content of your emails. By analyzing patterns in headers, sender behavior and your historical engagement, it makes accurate priority decisions without any access to email content. This metadata-only approach provides strong inbox intelligence while maintaining complete email privacy.
SaneBox delivers email intelligence with a unique privacy-first approach that works across all email clients without platform lock-in. Explore all features →

SaneBox has given me back control of my inbox after years of chaotic email management. The SaneLater folder handles all my newsletters and low-priority correspondence automatically, leaving my primary inbox with only the emails that actually need attention. I save at least 45 minutes daily on email triage. The metadata-only privacy approach also aligns with my legal practice's confidentiality requirements — I don't need to worry about email content being processed externally.
Excellent, underrated email tool that does exactly what it promises with minimal setup. The initial 1-2 week learning period required some training — I moved some incorrectly filtered emails to teach it my preferences — but after that period the accuracy has been consistently high. The SaneBlackHole is my favorite feature: I've permanently eliminated dozens of newsletter sources with zero friction. Very good value at the pricing point.
I tried SaneBox somewhat reluctantly after years of elaborate Gmail filter rules. The AI filtering is significantly smarter than rule-based approaches and requires far less maintenance. I particularly appreciate that it works with Apple Mail on my devices and Outlook on my work machine — one subscription covering all my email environments without any configuration changes. Recommend to anyone tired of inbox management overhead.
