Automate sending policy updates to all staff via email

Send new or updated policy documents to every user automatically, track delivery, and verify that the right version reached everyone.

The problem

Manually pushing policy updates is slow, error-prone, and impossible to audit reliably. People miss updates, or receive the wrong version, and there’s no way to confirm delivery at scale.

How it works

  1. Store the new policy document in a controlled Drive folder.
  2. Build a recipient list from the current user directory.
  3. Send templated emails with the policy link and version to each user via the delegated service account.
  4. Log each send for later audit.

What changes

Every user receives the latest policy update promptly, and admins can prove who got which version, when.

The trap in this one. Gmail API’s per-user daily send quotas still apply to the service account, even under domain-wide delegation. If you approach the quota, messages silently queue and can be delayed for hours, but no explicit error is returned—delivery appears successful in logs until users report missing emails.

Questions people ask

How do we track which users received which version?

Log every send event, including the document version and timestamp, to a secured Sheet or database. This provides a clear audit trail.

Can we use a group address instead?

You can, but group delivery lacks individual tracking and can trigger spam filtering or rate-limiting at scale. Direct sends are more auditable.

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.
