DeepSeek Lead Scoring n8n Workflow: Webhook → Gmail Routing

Instant DeepSeek Lead Scoring in n8n — Webhook Intake to Gmail Routing

Capture new lead submissions with a webhook, have DeepSeek score each lead from 1 to 100, automatically prevent duplicate processing with an n8n Data Table, and route approvals via Gmail—all inside an n8n workflow.

What this workflow does

This DeepSeek Lead Scoring n8n workflow follows a clear pipeline:

• Webhook intake: Receives a lead submission via a POST webhook (raw_client_input plus selected_service).
• Normalization + deduplication: Generates a deterministic lead_unique_id, then checks an n8n Data Table to skip leads already processed.
• Audit + enrichment: Upserts the lead into the Data Table as an audit record, then sends the submission to the DeepSeek Chat Completions API to return structured fields and a priority_score (1–100).
• Decision routing: Uses a three-way switch based on priority_score:
  • High scores → sends an approval email to one Gmail destination.
  • Mid scores → sends a fast-track approval email to another Gmail destination.
  • Low scores → sends a polite decline email.
• Approval handling: Receives an approval click via a second webhook, validates the decision, appends the approved lead to a Google Sheets fulfillment spreadsheet, and returns an HTML confirmation page.
• Failure alerting: If the DeepSeek request fails, sends a critical alert email via Gmail for troubleshooting.

Use cases

• Score inbound form leads and route them to the right sales approvals automatically.
• SaaS operators needing deterministic lead deduplication and audit trails with n8n Data Table.
• Automation engineers deploying a webhook-to-LLM scoring workflow with Gmail decision routing.
