Send AI website audits with GPT-4.1 and Gmail as a lead magnet

How it works

- A prospect submits a form with their email and website URL - The workflow fetches and cleans the website HTML, extracting key business signals - An Analyst Agent reads the content and produces a structured JSON diagnostic (business type, offers, pain points, funnels, copy kit) - A Writer Agent converts the diagnostic into a personalised email with 10 actionable improvements, written automatically in the lead's language - A branded HTML email is assembled and sent via Gmail with numbered improvement cards, a booking CTA and a professional footer
