Guide: Gmail Governance Without Inbox Browsing — Audit Email Security the Right Way

Gmail Governance Without Inbox Browsing

IT admins need to audit Gmail security — forwarding rules, delegates, risky filters — but reading employee email crosses a line most organizations don't want to touch.

There's a governance-safe approach: audit the configuration without browsing the content. Four areas tell you almost everything you need to know about a user's Gmail security posture:

1. Forwarding — Is auto-forwarding enabled? Where does it go? Is the destination verified?
2. Delegates — Who else can read and send from this mailbox?
3. Filters & Routing Risks — Are any filters forwarding externally, mass-deleting, or using broad from:any patterns?
4. Mailbox Health — Unread count, total messages, storage used (metadata from the Reports API — no content access)

None of this requires gmail.readonly (which grants access to message content). It uses gmail.settings.basic and the Admin Reports API.

We wrote a detailed technical walkthrough on this approach:
