Help me set up this automation using n8n + Gmail + Google Sheets + OpenAI: "n8n customer support email triage with AI reply drafts". Goal: replace Helpdesk first-pass triage. How it should work: - Trigger: Support email arrives - Then: Classifies it - Then: Logs a ticket to Sheets - Then: Alerts Slack if urgent - Result: FAQ-based reply draft (never auto-sent) Setup steps (summarized from the original source): 1. Connect Gmail 2. Write FAQ/business info 3. Add OpenAI credential 4. Create log sheet 5. Activate Guide me one step at a time. Ask me for anything you need (accounts, sheet or channel names) before you start. Safety rules: - Build and test with sample data first, and show me a sample result before anything goes live. - Keep anything that goes to other people (emails, posts, replies, record updates) as drafts for my review until I say otherwise. - Never send, post, buy, pay, delete or change records without my approval. - Tell me about any cost (paid plans, API usage) before I'd incur it, and help me set a spending limit. - Keep API keys and passwords out of shared docs and chats. - Privacy: Email content is sent to the LLM provider (e.g. OpenAI). Needs Gmail OAuth access to read, label and draft. Based on: https://n8n.io/workflows/18047-triage-support-emails-and-draft-ai-replies-with-gmail-google-sheets-and-openai/
