A hidden field in a contact form allows you to gather UTM parameters from your site visitor's landing URL and send them as a form field response. This will come in handy if you want to track the effectiveness of your advertising campaigns, figure out where the traffic is coming from and what exactly leads people to your website.

Note: the hidden field will be invisible on the published site.
