SerpApi + GPT-4o Lead Enrichment & Outreach in n8n

Automatically enrich form leads with SerpApi + GPT-4o and send personalized outreach from n8n

This n8n workflow captures website visitor form submissions, researches the visitor’s company using SerpApi, extracts structured insights with OpenAI (gpt-4o-mini), drafts a tailored outreach email, logs everything to Google Sheets, and alerts your team in Gmail—with Slack failure notifications.

What this workflow does

• Receives lead data from an n8n Form trigger (contact details, company information, and stated interest).
• Normalizes fields into a consistent lead profile for reliable downstream use.
• Queries SerpApi twice:
  • Collects company overview signals (e.g., size, funding, and tech stack signals) via Google search results.
  • Finds the company’s LinkedIn page via search results.
• Uses OpenAI (gpt-4o-mini) for structured enrichment from the search snippets, extracting items like LinkedIn URL, size, funding, tech stack, news, and competitors.
• Generates a short outreach email draft (subject + body) using OpenAI (gpt-4o-mini), tailored to the visitor’s details and the extracted company intelligence.
• Updates your CRM by appending the enriched lead to a Google Sheets tab.
• Notifies sales by sending an HTML-formatted Gmail message to the sales rep with the research summary and the outreach draft.
• Slack alerts on failure, including dedicated alerts for the AI research and AI outreach steps.
