Policy decides.

Most outbound tools help you send more. Outbound OS determines when not to send. Change the conditions below and watch the real project gate evaluator decide.

Every input is synthetic. These controls model pre-approved facts; they do not validate an actual mailbox or authorization.

Every gate, explained

FAIL-CLOSED POLICY
    Simulation, not permission to send. Even when the result is PASS, this page never creates a transport, contacts a mailbox, or sends an email. It uses the exact evaluateSendGates and validateDraft functions from the repository.

    Built for systems that need proof.

    The real CLI, MCP server and Zoho adapter live in the GitHub repository. The browser demo shows policy decisions only; it is not a production email-verification service.
