n8n Gym Trial Lead Automation: GPT-4o, Sheets & Gmail Routing

Turn Gym Trial Leads Into Action—Instantly

This n8n workflow captures gym trial form submissions via webhook, uses OpenAI GPT-4o to qualify and prioritize each lead, logs everything to Google Sheets, and sends follow-up emails through Gmail. Hot leads also trigger an immediate Telegram alert to your front desk.

What this workflow does

• Receives new trial leads via an n8n webhook (POST request) from your gym trial form.
• Normalizes incoming data (name, email, phone, goal, preferred time, source) and adds a submission timestamp (loggedAt).
• AI lead scoring with GPT-4o: GPT-4o returns structured results including priority (hot/warm/cold), leadScore, reasoning, and a personalized opening line.
• Logs results to Google Sheets in the “Trial Leads” tab, appending fields like priority, leadScore, and reasoning.
• Email routing via Gmail:
  • Hot leads receive a fast-track welcome email.
  • Warm leads receive a standard nurture email.
• Telegram front desk alerts for hot leads, sending the lead details immediately.

Use cases

• Automate first-response follow-up for gym trial signups without manual review.
• Give your sales team a real-time queue by prioritizing leads automatically (hot/warm/cold).
• Maintain a single source of truth in Google Sheets for reporting and lead auditing.
• Notify the front desk instantly when a lead is likely to convert.
