n8n Contact Form to Google Sheets + Gmail Reply Automation

Turn “Contact Us” submissions into saved records—and instant email replies

This n8n workflow automatically captures form submissions from an n8n Form trigger, appends the details to Google Sheets, and sends a Gmail-based thank-you email to the submitter’s address—so you can respond faster and keep a clean log of every message.

What this workflow does
