Generate Cold Emails & Sales Letters with OpenAI GPT & Google Docs via Chat

This workflow automates content creation for sales and marketing by listening for incoming chat messages via a webhook or form trigger. It feeds the message, along with conversation memory, into a custom OpenAI Chat Model configured as a 'Copy Assistant' with two specialized tools: Cold Email Writer and Sales Letter Generator. The AI intelligently selects and executes the appropriate tool based on user intent, producing polished, professional copy tailored to prompts like 'Write a cold email for a fintech startup' or 'Create a sales letter for B2B SaaS.'

The generated content is then automatically written to your specified Google Doc or Microsoft Word document using the Update a Document node, streamlining the process from idea to draft. Benefits include massive time savings on copywriting, consistent high-quality output powered by GPT, and context persistence across chats via Simple Memory, making it ideal for iterative refinements.

Use cases span marketing teams crafting outreach campaigns, sales reps personalizing pitches, solopreneurs scaling email funnels, and agencies producing client deliverables. No manual copying—results land directly in editable docs. Setup requires OpenAI API key, custom Assistant ID, credentials for memory and docs, and chat endpoint configuration, with sticky notes guiding prompt tweaks.
