A large number of pages created with Instapage will have a form on them. To add one, locate the Forms library in the page builder, on the left-side menu. Forms can be placed on the main page, as well as in pop-ups.
From there, you can choose to select an already-created form, use one of our templates or create a new form.
To learn more about creating forms, please refer to the dedicated article here: https://d.pr/3yDW36
After adding a form to the page, you can change the form and button style and choose whether the form will be visible on both Desktop & Mobile or just one of them.
In order to test the form submission, make sure you publish the page first, as it cannot be tested in Preview Mode.
