The Inbox Stops Setting the Agenda
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.
Who this is for
Coaches, consultants, and agency owners whose first working hours go to the inbox. Worth building when volume is high enough that reading and sorting is itself the job, and most replies are variations on the same handful of answers.
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.
