The problem

Shared inboxes receive high volumes of inbound mail, and messages routinely slip through without a response. Manual triage is inconsistent, and important emails risk being missed or actioned too late.

How it works

  1. Use a service account with domain-wide delegation to impersonate the shared inbox.
  2. List messages in the inbox filtered by label or status (e.g. 'unread', 'no response').
  3. For each matching message older than the escalation threshold, apply an escalation label or forward to a supervisor.
  4. Repeat on a schedule appropriate to inbox volume.

What changes

Unattended emails are surfaced automatically, reducing the chance of missed requests and ensuring response targets are met.

The trap in this one. The Gmail API's 'labelIds' filter only matches messages with all listed labels, not any. If you filter for 'INBOX' and a custom status label, messages missing one are silently excluded. This causes the escalation logic to skip emails that should be actioned. Always test your search queries and label logic on live data, and beware that label application can be delayed by minutes in high-traffic inboxes.

Questions people ask

Can this detect emails that have been read but not replied to?

You can check for the 'SENT' label or absence of a reply thread, but it's not foolproof. Some replies may not trigger the expected thread behaviour.

Will this work with delegated access to a Google Group?

No, the Gmail API only works with user mailboxes, not Groups. You need to route mail into a real mailbox.
