Subscription forms are a great way to quickly and easily grow your email list. Whether it is a subscription form on your website or a form included within a landing page, our platform gives you the ability to prefill field values by using URL parameters making the sign-up process even easier.
In this example, your form's publish URL is https://mydomain.com/about. Suppose that after creating your subscription form, you want to pass the value John for the field Name. You can do this by adding the parameter name=John at the end of your URL:
https://mydomain.com/about?name=John
So, when someone visits the above URL, the value John appears automatically on the Name field.
