Support Inbox Triage with Human Review

Incoming support email is classified, tagged, and routed to the right queue with a drafted reply, but a human approves before anything sends, so triage is fast without going unsupervised.

Problem

The operating gap

A shared support inbox becomes a pile. Messages get classified inconsistently, urgent issues sit behind routine ones, and agents burn time sorting and writing the same first responses. Teams want speed but won't let automation reply to customers unsupervised.

Build

What gets built

New inbound email triggers a workflow that extracts intent and urgency, applies category labels, and routes the thread to the correct queue or owner. For common categories it generates a suggested reply held as a draft, never auto-sent. Low-confidence or sensitive messages are flagged for priority human review. The classification step is bounded to labels and routing only, so the human always makes the send decision and the audit trail stays clean.

The architecture connects on new inbound support email, n8n, gmail/imap, and completed workflow with an explicit control path.
