GPT-4o Lead Scoring n8n Workflow: HubSpot, Slack & Sheets

Instant GPT-4o Lead Scoring for Your n8n Pipeline (HubSpot + Slack + Sheets)

This n8n workflow receives new leads from a webhook, normalizes the data, scores them with GPT-4o (0–100), then automatically routes hot leads to HubSpot and Slack—while cold leads get a nurture email and are logged to Google Sheets.

What this workflow does

• Captures leads via webhook: A website/landing-page form sends a POST request to the workflow endpoint (path: /new-lead) with lead details.
• Normalizes inbound fields: The workflow standardizes key attributes (such as email and company) so downstream steps are consistent.
• Scores with GPT-4o: The lead data is sent to OpenAI (GPT-4o), which returns a JSON response containing a 0–100 score, a tier, and reasoning.
• Splits hot vs cold leads: It extracts the numeric score and branches based on whether the score is at least 70.
• Hot leads (score ≥ 70): Creates a new deal in HubSpot and posts an alert to the #sales-hot-leads Slack channel.
• Cold leads (score < 70): Sends a thank-you/nurture email, then appends the lead to Google Sheets for reporting.

Use cases

• Route inbound form leads from your SaaS to sales instantly—using GPT-4o scoring criteria.
• Automate lead triage by sending only the most promising prospects to HubSpot and alerting your sales team in Slack.
• Maintain a clean reporting trail in Google Sheets for lower-scoring leads while they enter email nurture.
