* Metadata only. We never request body-reading scopes.
Your email stays yours
InboxWatch scans infrastructure, not inboxes. Here's exactly what we access and what we don't.
Official OAuth
Same secure sign-in as Google and Microsoft. We never store your password.
Metadata only
We scan headers, rules, and settings. Never message bodies or attachments.
No admin access needed
Connect your own account in 60 seconds. No IT department required.
Revoke anytime
Remove InboxWatch from your account settings. Access ends immediately.
Broader email risk coverage
Beyond the core scanner: phishing tests, breach monitoring, domain protection, and continuous risk assessment.
Less noise. More real threats.
InboxWatch learns your environment over time, automatically suppressing false alarms so your dashboard stays focused on what actually needs attention.
Learns your patterns
Mark a false positive once and the AI remembers. Trusted senders and known configs stop generating alerts automatically.
Suppresses noise
High false-positive findings are automatically suppressed. Your dashboard stays focused on real threats.
Full transparency
See what the AI suppressed, why, and restore anything with one click. Track accuracy trends and review history.
Built for AI agents
MCP server, REST API, and webhook alerts. Integrate into any workflow.
Frequently Asked Questions
Yes. InboxWatch uses official OAuth, the same secure sign-in you use with other trusted apps. We request only metadata permissions (mail headers, rules, sign-in logs) and never access message content. You can revoke access instantly from your Google or Microsoft account settings.
