Audit and enforce consistency of email signatures

Check and report on whether every user has the correct email signature, catching manual edits and drift across the domain.

Who it is forIT administrators responsible for brand compliance and regulatory disclaimers in outbound email.

Typical scopesgmail.settings.basic, admin.directory.user.readonly

The problem

Left unchecked, user signatures drift: people edit them, ignore updates, or strip out required elements. This creates compliance gaps, inconsistent branding, and missed legal disclaimers.

How it works

  1. Enumerate all active users with Admin SDK.
  2. For each user, impersonate and fetch their current Gmail signature using the Gmail API.
  3. Compare the signature to the approved template, flagging differences.
  4. Report or remediate out-of-policy signatures as required.

What changes

Administrators can see at a glance which users are out of compliance and take targeted action, rather than relying on policy reminders or spot checks.

The trap in this one. Gmail API's settings endpoints are eventually consistent and cached per user. After a bulk signature update, immediate reads may return stale data for several minutes — audits run too soon will generate false positives. Always allow for propagation delay after changes.

Questions people ask

Can I force-refresh signature data instantly?

No. The Gmail API does not provide a cache-busting or force-refresh mechanism; propagation delays are outside your control.

What if a user has multiple 'send as' addresses?

Each 'send as' address can have a different signature. Audit all configured addresses, not just the primary.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
