• As promised, here's the json file: Click here to watch the video

This workflow automatically generates draft replies in Gmail.
It's designed for anyone who manages a high volume of emails or often face writer's block when crafting responses.
Since it doesn't send the generated message directly, you're still in charge of editing and approving emails before they go out.

How It Works:

• Email Trigger: activates when new emails reach the Gmail inbox

• Assessment: uses OpenAI gpt-4o and a JSON parser to determine if a response is necessary.

• Reply Generation: crafts a reply with OpenAI GPT-4 Turbo

• Draft Integration: after converting the text to html, it places the draft into the Gmail thread as a reply to the first message
