The Bottom Line

The emails you need to deal with are taking hours you shouldn't be spending. That's the real problem. Not the newsletters. Not the automated receipts. The actual emails from actual people that require an actual response.

SaneBox solves a different part of this. It filters out noise — routing low-priority email into folders like @SaneLater and @SaneBlackHole based on sender history. Volume goes down. That's a genuine benefit. But once the noise is cleared, the work is still yours. SaneBox doesn't read the emails that make it through, doesn't draft replies, doesn't track whether that client ever wrote back.

Clarity works on the emails that matter. Inside your Gmail or Outlook, it labels every message by urgency and intent, drafts replies in your voice, tracks every sent email for follow-ups, and sends a morning brief of what actually needs you. Not faster email. Less email that you have to think about.

They're complementary if you want both. SaneBox quiets the inbox. Clarity handles what's left. If you're choosing one, ask yourself: is the problem volume, or is it the time you spend on the emails that count?
