See every featureContact forms attract spam, including the new AI-written kind that reads like a real customer enquiry. FormFence sits in front of your existing contact form and blocks both. It's invisible: no CAPTCHA, no puzzle, no extra step for the people who actually want to talk to you. You see a clean log of what was blocked and why. Real enquiries go straight to your inbox.
AI Form Builder replaces hours of drag-and-drop form building with one sentence. Describe what you want to ask, and the AI writes a complete contact form, survey, feedback or NPS form: the right field types, multi-page layout, conditional logic and a thank-you message, in your store's language. Edit by typing a change and review it before it applies. 21 field types, from star rating to file upload.
