n8n Webhook Contact Form → Google Sheets Log + Gmail Alerts

Turn website contact form submissions into logged data + instant Gmail alerts

This n8n Webhook Contact Form workflow captures HTTP POST submissions from your website, appends every lead to Google Sheets, and immediately sends a branded HTML notification to your inbox via Gmail—with the submitter’s email set as the Reply-To.

What this workflow does

• Receives contact form data through an n8n webhook (HTTP POST).
• Uses your notification recipient email to determine where alerts are sent.
• Appends the submission to Google Sheets, logging: Date, Time, Name, Email, Phone, and Message.
• Generates a branded HTML email notification using the submitted form data.
• Sends the notification via Gmail, using the submitter’s email as the Reply-To address so you can respond directly.

Use cases

• Route new website contact form inquiries to your team with both a spreadsheet record and email alerts.
• Ensure every lead is auditable by storing submissions in Google Sheets for later review or reporting.
• Help SaaS operators and automation engineers consolidate inbound messages without relying on manual copy/paste.
