n8n multi-agent email workflow using GPT-4.1-mini for classification and a Claude 3.7 agent for support responses

The problem

Email triage and first responses were eating the team's hours. Every message needed a human to read it, decide what it was, and start a reply. The inbox set the agenda for the whole day.

What I built

A multi-agent email system in n8n. One model triages, specialized agents respond:

  • GPT-4.1-mini classifies every incoming email by type and urgency
  • Routing logic hands each email to the right specialized agent
  • A Claude 3.7 agent handles support conversations
  • Auto-labeling keeps the inbox organized without human sorting
  • Response drafts are ready before anyone opens the thread

The result

Email triage and first-draft responses handled autonomously at scale. Humans review and send. They no longer start from zero.
