The problem

Welcome emails are often forgotten or sent inconsistently when handled manually, and scheduling from a personal account is unreliable. Using a delegated service account ensures consistency, but introduces edge cases in delivery and visibility.

How it works

  1. Detect new user creation from the authoritative source (e.g. HRIS or Directory).
  2. Queue a welcome email with a scheduled send time, using the Gmail API and service account delegation.
  3. Send on behalf of the service account, so all messages are consistent and auditable.
  4. Log delivery status and alert if the send fails or is delayed.

What changes

Every new user receives a standardised welcome email at the right time, with no manual intervention or missed messages.

The trap in this one. Scheduled sends using the Gmail API with delegated service accounts are not visible in the user's own Sent or Scheduled folders—only the sending account sees them. If a user is migrated or removed before the scheduled time, the message is silently dropped by Gmail; there is no bounce or error callback. Always track delivery status and reconcile against user lifecycle events.

Questions people ask

Can we customise the email per user?

Yes, the body can be templated and filled with user-specific details at scheduling time. Just be mindful of encoding issues with personalisation.

Does the user see who sent the email?

The message appears from the service account or its alias, not from HR or IT directly. If a personal touch is needed, set an appropriate display name.
