The problem

Manual reminders are error-prone and easily forgotten, especially across multiple tenants. Scheduled automation guarantees consistency, but delegation introduces quirks in message delivery and auditability.

How it works

  1. Prepare the reminder template and recipient list in a secure location.
  2. Use a scheduled job (e.g., Cloud Scheduler) to trigger the automation at the required interval.
  3. Have the delegated service account impersonate each user and send the message using the Gmail API.
  4. Log message IDs and delivery status for audit purposes.

What changes

Reminders are sent reliably and on time, with a verifiable record of delivery across all target users.

The trap in this one. Gmail API’s send-as-user via delegation will silently drop messages if the user’s mailbox is disabled, suspended, or over quota—no error is raised in the API response, just a missing message. Always check for actual message presence post-send, not just a 200 response.

Questions people ask

Can I send from a generic compliance address via delegation?

Only if that address is a real user or group with mailbox access. Delegation cannot impersonate aliases or groups for sending.

How do I avoid sending to users who have left?

Sync your recipient list with the active users directory immediately before each run; stale lists are a common cause of silent non-delivery.

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.
