A switch routes each email to either an automated reply, a generated draft for human review, or no action. The reply and draft paths use AI generation with shared knowledge-base and model resources before sending or flagging the result in Gmail.\n\n### Setup steps\n\n- Connect Gmail credentials for the trigger, email fetch, reply, and human-review flag actions.\n- Configure the Gmail Trigger with the mailbox, labels, or search criteria that should start the automation.\n- Add OpenRouter credentials and choose the chat models used by the classification, reply-generation, and draft-generation agents.\n- Connect Google Docs credentials and point the knowledge-base tools to the documents that should inform generated responses.\n- Review the switch rules so the classification output maps correctly to reply, draft, or no-action branches.\n\n### Customization\n\nCustomize the AI prompts, classification categories, switch routing rules, Gmail labels, and Google Docs knowledge sources to match the organization\u2019s email handling policy." }, "typeVersion": 1 }, { "id": "35e02ef5-731b-4e8b-9ddf-b4a17a63fbda", "name": "Sticky Note1", "type": "n8n-nodes-base.stickyNote", "position": [ 688, 304 ], "parameters": { "color": 7, "width": 848, "height": 656, "content": "## Receive and classify email\n\nStarts from the Gmail trigger, fetches the incoming message, and classifies it with an AI agent supported by its OpenRouter chat model.
