AI Lead Scoring Workflow: Webhook → HubSpot + Slack Alert

Score every new lead in real time—then notify your team on Slack

This AI Lead Scoring Workflow for n8n receives new lead submissions via a webhook, uses OpenAI to generate a 1–10 lead score with a short reason and summary, upserts the contact into HubSpot, sends a thank-you email, and posts a Slack alert whenever the score meets your configured “hot lead” threshold.

What this workflow does

• Receives leads via a webhook POST endpoint whenever a new lead is submitted.
• Normalizes incoming data into a consistent lead object (name, email, phone, company, message, source).
• Scores the lead with OpenAI using Chat Completions, returning a JSON response with a 1–10 score, plus a brief reason and summary.
• Enriches the lead record by attaching the score, reason, and summary for downstream actions.
• Sends a thank-you email through your SMTP server, including a booking link for follow-up.
• Upserts into HubSpot as a contact, using the email address as the unique identifier.
• Notifies Slack via an incoming webhook when the score is greater than or equal to the configured hot-lead score.

Use cases

• Qualify inbound leads from your web forms and immediately flag high-intent prospects.
• Route “hot leads” to sales/CS via Slack while still capturing every lead in HubSpot.
• Automate response emails with a booking link to increase follow-through—without manual CRM work.
