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
