n8n Email Operating System
Event-driven email workflow in production. Inbox triage, classification, routing, human review.
Event-driven distributed email workflow in production. n8n with custom code handles inbox triage, classification, routing by topic and priority, structured event logging, follow-up scheduling, and human-in-the-loop review for high-priority replies before they go out.
The problem
Inbound email at the client was being managed in a shared inbox with a spreadsheet for tracking. Triage was manual and inconsistent. Routing decisions did not survive a context switch. There was no audit trail for what got answered or escalated. Replies sometimes went out before anyone with authority had seen them.
What we built
An event-driven distributed workflow in n8n, with custom code at the integration seams. Incoming messages are classified and routed by topic and priority. Every event is logged to a structured store. Follow-ups schedule themselves. High-priority replies route through a human-in-the-loop review gate before sending.
What was delivered
- n8n classification and routing workflow with custom code at integration seams
- Structured event log capturing every inbound message and action taken
- Follow-up scheduling and reminder logic
- Human-in-the-loop review gate for high-priority replies
Outcomes
- Triage and routing handled automatically and consistently
- Full audit trail across inbound activity
- Response times faster and more consistent
- Manual coordination overhead reduced; the team works on what only the team can do
