Nothing is ever sent to customers automatically.\n\n## How it works\n\n1. **Gmail Trigger** polls the inbox and picks up new support-style emails (search query set on the trigger).\n2. **Configuration** centralizes every setting you might change (product name, IDs, reviewer email, score threshold, AI model).\n3. **Clean the email** strips signatures and quoted replies so the AI sees only the real message.\n4. **Extract FAQ candidate** (OpenAI + Information Extractor) returns structured JSON: question, safe draft answer, category, urgency, FAQ value score, sensitivity flag, tags, recommended action, and reasoning.\n5. **Prepare candidate** computes a routing status and builds the draft texts.\n6. **Log to Google Sheets** appends every candidate for tracking.\n7. **Route** sends strong candidates to a Google Docs draft + a Gmail notification, unclear/sensitive ones to a Gmail review draft, and the rest to log-only.\n\n## Setup\n\n1. Connect credentials: Gmail, OpenAI, Google Sheets, Google Docs.\n2. Create a Google Sheet with a tab (default name **FAQCandidates**) whose header row matches the logged columns.\n3. Open **Configuration** and set: product/service name, Google Sheet ID, sheet tab name, Google Docs folder ID, reviewer email, FAQ score threshold, and AI model.\n4. Adjust the Gmail search query and polling interval on the **Gmail Trigger** node to match your inbox and languages.\n\n## Requirements\n\n- Gmail, OpenAI, Google Sheets and Google Docs credentials in n8n.\n- A Google Sheet with a **FAQCandidates** tab and the expected header columns.\n- A Google Docs folder ID where FAQ drafts will be created (defaults to Drive root).\n\n## Customization\n\n- Change the Gmail search query, polling interval, score threshold, categories, tags, or draft wording.\n- Swap the AI model in one place via the **Configuration** node (default: gpt-5-mini).\n- Extend the schema in **Extract FAQ candidate** (e.g. add sentiment or product area).\n\n---\n\nNeed help customizing?\nContact me for consulting and support : [Linkedin](https://www.linkedin.com/in/doctor-firass/)\n\n# MY NEW YOUTUBE CHANNEL\n\ud83d\udc49 [Subscribe to my new YouTube channel](https://www.youtube.com/@DrFiras_AI).
