AI Lead Scoring & Routing in n8n: OpenAI, Slack, Notion, Sheets

Instant AI Lead Scoring & Routing in n8n—Powered by OpenAI, Slack, Notion, and Google Sheets

Turn every new lead form submission into an AI-scored, immediately routed action. This n8n workflow uses OpenAI to score leads, assigns “hot” leads to SDRs in round-robin rotation, alerts your team in Slack, and logs results to Notion and Google Sheets.

What this workflow does

• Receives leads via webhook: Accepts a new lead submission as a POST request to an n8n webhook.
• Classifies the email domain locally: Determines whether the email domain looks business or personal before scoring.
• Scores with OpenAI (JSON output): Sends lead details to OpenAI to return a structured response including lead score, tier (hot/warm/cold), reasoning, and a suggested next step.
• Handles AI parsing failures: If the OpenAI response can’t be parsed, it posts a message to a Slack review channel for manual scoring.
• Routes hot leads automatically: For hot leads, assigns the next SDR using round-robin rotation and sends a Slack alert with the score and assignment; otherwise, places the lead in a nurture queue.
• Persists lead data: Creates a lead record in Notion, sends a tailored confirmation email via Gmail, and appends tier/score/timestamp/assignment to Google Sheets.

Use cases

• SaaS teams who want AI lead scoring and immediate routing for faster SDR response times.
• Ops/automation engineers building a webhook-to-CRM-style pipeline without leaving n8n.
• Teams that need audit-friendly logging to both Notion and Google Sheets, plus Slack notifications for visibility.

Technical details (n8n integrations)

• Webhooks + Code/if nodes for workflow control and domain classification.
• OpenAI for JSON lead scoring (score, tier, reasoning, suggested next step).
• Slack for hot-lead alerts and review-channel messages when parsing fails.
• Notion to create a lead record with mapped properties (e.g., status, email, lead score).
• Gmail to send confirmation emails.
• Google Sheets to append lead details (tier, score, timestamp, assignment).

Setup tip: Add credentials for OpenAI, Slack, Notion, Gmail, and Google Sheets, then update config values (Slack channel IDs, Notion database ID, Google Sheet ID, and the SDR email list for round-robin routing).
