n8n Webhook Lead Intake Automation: Normalize Email & Phone

Normalize every inbound lead—automatically validate, clean, and prepare a human-ready summary from an n8n Webhook

Stop wrestling with messy lead payloads. This n8n Webhook Lead Intake Automation receives inbound leads via a POST webhook, validates required contact information, normalizes email and phone, and generates a structured summary plus a draft reply for human review—without automatically sending customer-facing messages.

What this workflow does

• Receives leads through a Webhook (POST): The workflow accepts an inbound lead payload and processes it end-to-end.
• Validates required fields: A Code step checks the event ID, lead name, and that at least one contact method is present—email or phone.
• Normalizes contact data: Email and phone values are cleaned into a consistent format so downstream systems can use reliable data.
• Handles invalid submissions clearly: If required information is missing, it returns a validation response that specifies which fields are missing.
• Prepares reviewable outputs: For valid leads, it produces normalized lead data, an internal summary, and a suggested reply—while keeping the next step under human approval.
• No automatic outreach: The workflow explicitly does not send customer-facing messages automatically.

Use cases

• Lead intake from a form or landing page that posts to an n8n webhook, even when users submit inconsistent phone/email formats.
• CRM onboarding where you want validated + normalized data before creating records or assigning follow-up.
• Sales ops teams that need a structured summary and reply draft for agents to review before contacting prospects.

Technical details

• Uses n8n nodes: Webhook, Code, and Respond to Webhook.
• Requires an n8n instance with these nodes available.
• Best practice: review the Webhook, Code, and Respond to Webhook nodes before activation, then test with a production webhook POST containing event ID, lead name, and email or phone.
