To ensure that the form is rendered same as in our demo (input and button in one line) go to MC4WP / Form and remove all extra html from the form content (“Form code” field (1)). Leave only the fields tags, as following:
<input type="email" name="EMAIL" placeholder="Your email address" required />
<input type="submit" value="Sign up" />

Add sign up form to the content
To add newsletter form to a page content you need to use it shortcode. You can find it below the form title on form edit page (Image above 2).
E.g.: [mc4wp_form id=3598]
Copy this code and paste in a text area in a page builder (same as you are adding a text).

Or in a shortcode block if you are building page using wordpress built in editor:
