"content": "## Auto-triage Gmail inbox and draft replies using OpenAI GPT-4o\n\n### How it works\n\nThis workflow monitors Gmail for new inbound email, extracts key message fields, and uses OpenAI GPT-4o to classify urgency. Urgent emails are routed to a GPT-generated reply draft that is saved in Gmail and logged to Google Sheets. Non-urgent emails bypass reply generation and are logged separately in Google Sheets.\n\n### Setup steps\n\n- Connect Gmail credentials for both the trigger and draft-creation node, ensuring the account has permission to read incoming messages and create drafts.\n- Configure OpenAI credentials and set the desired GPT-4o model/prompts for urgency classification and urgent reply drafting.\n- Connect Google Sheets credentials and select the target spreadsheet/sheet for urgent and non-urgent email logs.\n- Verify the extracted email field mappings, urgency label values, and IF condition so the urgent branch matches the classifier output.\n\n### Customization\n\nAdjust the urgency classification prompt, branch condition, reply-drafting tone, and Google Sheets columns to match your team\u2019s triage criteria and reporting needs."
