If it drafts instead of sends, you catch the mistake before the customer sees it. ## Make it drafts-only (n8n Gmail Tool) 1. **Resource** opens on Message, and the operation is send. Choose **Draft**. The operation switches to **Create**. 2. Under **Add option**, set **Thread ID** to `{{ $json.threadId }}` so the draft sits under the customer's email. 3. Add **To Email** set to `{{ $json.From }}`, so you can just hit send after you read it. 4. Keep the email type on text. Plain text reads more like a person. ## Give it facts and rules Copy ```text Rules: You cannot send email. You can only create drafts. If you don't know something, say someone from the team will follow up. Never make up prices, dates or services. ``` From the Greenline system message. The rule helps, but choosing the Draft resource is what makes sending impossible. ## Keep private data out - Before you paste a thread into ChatGPT, leave out anything private, like a card number. - Scan for ID numbers, birth dates, account and card numbers, and health details. - The test: only the details this reply needs. Write a short facts list instead of pasting whole records. ## Watch for text that gives orders - Prompt injection: an email the AI reads can hide instructions, like "ignore your rules." The model can't always tell data from commands. - Give an agent only the tools its job needs. Drafts, not sends. - Wrap outside text in clear delimiters, like the `` tags in the lesson's prompt. ## Before you click Send - Read every draft for dates, prices and promises. - Ask ChatGPT for a table of every promise and the fact behind it, and fix anything flagged. - Review drafts daily. A pile of unread drafts helps no one. - If the agent keeps handing off the same question, add the answer to its facts. **Remember:** The AI writes the draft; a person reads it and clicks Send. Make that limit structural with a drafts-only tool, not just a line in the prompt.
