Yes, absolutely!

This plugin does not create any dynamic HTML content, as other popup plugins do. Performance was the top-criteria when creating this plugin. This means: Popups for Divi embraces every caching plugin you can throw at it!

Really, there is almost no PHP code at all. The actual plugin is a static JS file, which runs on the users browser. It’s typically is stored in browser-cache and can even be served via a CDN.
