Gmail Auto-Reply Draft with OpenAI Assistant - n8n Automation Template

This workflow automates the process of drafting email replies in Gmail using the power of OpenAI Assistant. It checks for incoming emails with specific labels, retrieves the latest message in a thread, and sends the content to OpenAI for generating a suggested reply. The AI-generated draft is then converted into HTML, encoded, and added back to the Gmail thread as a draft. Finally, the trigger label is removed to prevent duplicate processing.

Ideal for professionals and teams who want to speed up email communication while maintaining high-quality, AI-assisted responses.
