Email Auto-Reply Workflow

An n8n workflow that automatically responds to influencer emails using AI categorization and response generation.

Purpose

Reduce manual email handling for the marketing team. Most influencer questions are repetitive (login help, splash screen specs, approval times) and can be answered automatically. Complex or sensitive topics get escalated.

Architecture

Runs on n8n worker-1 (Digital Ocean), workflow name: Email Auto-Reply (Influencer).

Pipeline

1. Check Inbox — IMAP polling every 1 minute
2. Store Email Data — Extract sender, subject, body, message-id
3. AI Categorize — Mistral classifies as SPAM, BUSINESS, or REPLY
4. Route — SPAM/BUSINESS → forward to team; REPLY → continue
5. AI Agent — Mistral generates response using knowledge base + conversation memory
6. Can AI Answer? — If response contains ESCALATE_TO_HUMAN → forward to team
7. Send Reply — Resend API, threaded in the original email conversation

Escalation Triggers

Email Threading

Replies appear in the same Gmail thread using In-Reply-To and References headers from the original email’s Message-ID. Conversation memory is maintained per sender using n8n session IDs.
