Depending on the type of popup you choose to create, you'll find different content you can add to your popup under the Content tab in your popup editor.
Most popup types include fields for you to enter a Title and/or Body for your popup content. The exception is the Custom Image popup which allows you to upload an image and link it somewhere on your storefront.
Generally, your popup Title will be a brief sentence to grab a visitor's attention, while the Body text will go into some more detail on what the popup is for.
While most popup types include fields for Title and Body text, certain popup types allow you to add other types of content for more specialized purposes. Change the text in your Email Signup submit button, link your social accounts into your Social Follow popup, link to a page on your storefront using the Page Promotion popup, and more.
