Quick overview This workflow triggers on n8n form submissions, uses OpenAI (GPT-4o mini) to draft a short acknowledgment email, sends the auto-reply through Gmail, and appends the submission details to a Google Sheets spreadsheet. How it works 1. Triggers when someone submits the n8n “Contact Us” form with their name, email, and message. 2. Sends the submission text to OpenAI (GPT-4o mini) to generate a warm auto-reply that promises a human follow-up within one business day. 3. Sends the generated reply to the submitter via Gmail with the subject “Thanks for reaching out!”. 4. Appends the form submission data to a Google Sheets worksheet for tracking. Setup 1. Connect an OpenAI credential for the Chat model used to generate the email reply. 2. Connect a Gmail account credential and confirm the workflow is allowed to send email from that mailbox. 3. Connect a Google Sheets credential, replace the spreadsheet URL/ID in the Google Sheets step, and ensure the target sheet tab is named “Leads” (or update it to match your sheet).
