Description

📨 AI Newsletter Automation Workflow

🚀 Brief Overview (How It Works)

This workflow automates the complete process of generating and sending AI-powered newsletters. It starts with a form submission where the user provides a brand name, website, and topic query. The system then fetches relevant news, analyzes the brand’s visual identity (colors & logo), and uses AI to generate structured newsletter topics and content. Finally, it converts everything into a beautifully styled HTML email, saves it to Google Sheets, and sends it to all subscribers via Gmail.
