The problem

Manual sending of large-scale announcements is error-prone, inconsistent and lacks any delivery tracking. Delegated service accounts centralise control but introduce operational quirks not seen in user-driven workflows.

How it works

  1. Build the recipient list from the authoritative directory or group.
  2. Compose the announcement with required formatting and links.
  3. Send emails individually using the Gmail API under domain-wide delegation.
  4. Collect and review delivery and bounce logs for compliance.

What changes

Announcements go out reliably from a single controlled identity, with traceability and no risk of leaking drafts or missing recipients.

The trap in this one. Gmail API’s send quota applies per user, but messages sent too quickly from a service account can silently vanish—no error, no bounce, just missing from inboxes and sent mail. If you queue hundreds of sends without throttling, only the first batch lands; the rest are dropped by backend enforcement. Always implement rate limiting and check the Sent folder for actual delivery.

Questions people ask

How fast can I send announcements?

Stay well under 100 messages per user per minute to avoid silent drops. Even with high quotas, backend throttling is not documented and can change.

How do I confirm delivery?

After sending, poll the Sent folder to ensure each message appears. For high-stakes sends, enable delivery receipts and monitor bounce notifications.

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.
