Stop losing leads after hours with this intelligent AI-powered automation that instantly responds to every website form submission, 24/7. This n8n workflow transforms your contact forms into a professional lead-capture system that replies in seconds, not hours.

What this workflow does

When a visitor submits your website contact form, this automation kicks into action immediately. It validates all required fields from the form submission, then uses OpenAI's GPT-4o-mini to generate a personalized, professional reply tailored to the prospect's inquiry. The AI-crafted response is sent directly from your own email inbox via SMTP, maintaining your brand identity. Every lead interaction is automatically logged to a Google Sheet with complete details including the visitor's name, email, message, and the AI reply that was sent.
