Later, if you want to stop showing a popup, but want to keep its template, simply disable its status. This will not remove any of the popup settings.
The next step is to configure the Popup showing method, or to put it simpler – set the page that will show the popup. You can choose between Homepage, Specific Pages, All URLs, or CSS Selector.
You also need to set when the popup will be shown. It can be triggered on Window Load, Page Load, Body Click, Exit Intent, or Scroll Percentage.
The next set of options let you configure more details about when and how often the popup will appear.
