AI Lead Scoring Workflow: OpenAI + Gmail + CRM Webhook (n8n)

Instant AI lead scoring, CRM upsert, and Gmail reply—fully automated in n8n

This n8n workflow captures inbound website form leads via a webhook, enriches and scores them with OpenAI (gpt-4o-mini), upserts only qualified leads into your CRM via an HTTP API, and sends an immediate personalized Gmail reply.

What this workflow does

• Receives leads: Listens for a POST request from your website form using an n8n webhook.
• Normalizes and prepares data: Maps incoming fields (name, email, company, message) into consistent lead fields and extracts the email domain.
• OpenAI enrichment + scoring: Sends lead details to OpenAI (gpt-4o-mini) to return strict JSON with an intent summary, priority score, industry, company size, and reply angle.
• Routes qualified leads: Parses the OpenAI JSON response and checks the priority score. Only leads scoring 40 or higher follow the qualified path.
• Upserts into your CRM: Posts a JSON payload to your configured CRM HTTP endpoint with the enriched lead data (authentication headers/credentials are configurable).
• Instant Gmail auto-reply: Sends a personalized reply from Gmail using the AI-generated reply angle.

Use cases

• Turn “contact us” form submissions into prioritized sales-ready leads automatically.
• Enrich new inbound leads with intent, industry, and company size before creating CRM records.
• Send an immediate personalized acknowledgement to prospects while your team follows up on qualified leads.
