How to Stop Contact Form Spam on Wix
Public Wix forms can receive automated submissions. If built-in settings still leave unwanted messages, an added filtering layer can provide more signals and review controls.
Here is how a behind-the-scenes filter can be added through Wix custom code without presenting a visible CAPTCHA.
Why Wix forms collect spam
Wix forms are published on public pages that automated tools can find and submit to. If the built-in controls do not provide the content, reputation, or review settings you need, an added layer can evaluate those signals.
What an added filter can evaluate
A layered filter can score each submission using known disposable or bad senders, content patterns, bot behaviour such as instant submits, and optional AI rather than relying on a single checkbox. Configured thresholds determine which submissions are blocked, and borderline ones are held for review.
SpamShield adds this on top of your existing Wix forms via a small embed, with a dashboard to review and release messages.
Add it to your Wix site
Use Wix’s custom-code feature:
- Create a free SpamShield account and add your site.
- Copy the embed snippet from Site Setup.
- In Wix, go to Settings → Custom Code, add the snippet to load on all pages before the closing body tag.
- Publish and submit a test message to confirm it is captured.
Frequently asked questions
SpamShield evaluates form, sign-up, and review submissions using reputation, content, behaviour, and optional AI signals. Configured thresholds determine which submissions are blocked, while borderline submissions stay available for review. Any automated classification can be wrong, so test the setup and review uncertain decisions. It does not place a visible CAPTCHA on the protected form.
