Sponsorship Lead Qualifier: GPT-4o + Google Sheets + Gmail (n8n)

Qualify sponsorship leads instantly with GPT-4o, log them to Google Sheets, and follow up by Gmail—automatically (n8n)

This n8n workflow turns every sponsorship inquiry into an assessed, routed lead: it receives form submissions via a webhook, uses OpenAI GPT-4o to classify sponsor fit and draft a proposal opening, records results in Google Sheets, sends the right Gmail reply, and alerts your sales lead in Telegram for high-fit prospects.

What this workflow does

• Receives inquiries as a POST request through an n8n Webhook.
• Normalizes fields (company, contact, email, budget, industry, and event interest) and adds a submission timestamp.
• Qualifies the lead with GPT-4o by classifying fit as high / medium / low against defined sponsorship tiers, producing a structured output with:
  • matched fit level
  • proposal-style opening
  • reasoning
• Logs results to Google Sheets in a worksheet named “Sponsorship Leads”, including fit tier and reasoning.
• Routes follow-ups via Gmail:
  • High-fit: sends a personalized, proposal-style Gmail reply
  • Medium-fit: sends a standard Gmail info-pack reply
• Notifies sales instantly with a Telegram message when a high-fit sponsor is detected.

Use cases

• Automate sponsorship intake from a website form without manual review.
• Speed up response times with GPT-4o-generated proposal openings for qualified leads.
• Maintain a clean sales pipeline by saving fit tier and reasoning in Google Sheets.
• Trigger immediate human attention for top prospects via Telegram.
