Lead Enrichment Pipeline

Automated lead capture, deduplication, tracking, and notification pipeline. Captures leads from web forms via webhooks, deduplicates by email in Google Sheets, scores by source and engagement, sends team notifications. 3 production-ready n8n workflows included.

Lead Capture & Tracking Pipeline 🎯

Capture leads from any source, deduplicate by email, score by intent, track in Google Sheets, and notify your team — all automatically via n8n workflows.

Problem

Leads come from multiple sources (website forms, newsletters, strategy calls, product waitlists). Manually entering them into a CRM and following up is error-prone and slow. Hot leads go cold.

This pipeline captures, deduplicates, scores, and routes leads in real-time.

What It Does

1. Capture — Receives leads from webhooks (website forms, landing pages, chatbots)
2. Deduplicate — Checks Google Sheets for existing leads (email match via appendOrUpdate)
3. Score — Basic lead scoring based on source type and engagement signals
4. Store — Appends to Google Sheets with scoring data
5. Notify — Emails team with lead details and suggested next action

Note: This pipeline does not include third-party enrichment integrations (e.g., Clearbit, FullContact). To add enrichment, insert an HTTP Request node between the webhook and the Sheets node in the workflow, calling your preferred enrichment API.
