Generate cold emails & sales letters with OpenAI GPT & Google Docs via Chat

How it works - Trigger: Listens for an incoming chat message - Copy Assistant: Feeds the message (plus memory) into an OpenAI Chat Model and exposes two “tools”

Cold Email Writer Tool

Sales Letter Tool•

Tool execution: Depending on the user’s intent, the appropriate tool generates the copy • Save output: Writes the generated email or sales letter into your target document via the Update a document node

Set up steps - • Configure your OpenAI Chat Model credentials in n8n (no hard-coded keys!) - • Add and authenticate the Simple Memory credential (to keep context across messages) - • Create Google Docs (or MS Word) credentials for the Update a document node - • Ensure your Chat trigger is pointing at your incoming-message endpoint - • Mandatory: Drop sticky-note annotations on each tool node explaining where to enter API keys and how to tweak prompts

Once everything’s wired up, send a test chat message like “Write me a cold email for a fintech startup” and watch the workflow spin up a polished draft in your document.

How to use
