Hi, I am looking for a pop-up plugin, which is suitable not only for opt-in, but can be used to display information about certain products or services. Meaning the user doesnt have to fill in the form. Is this also possible with JD PopX? If not, what other popup can provide this features and can be fully customized?

Hello,

JD PopX opens automatically but is pretty limited to the content of the plugin itself. You have a few options.
Try Modals from regular labs. It almost has every option imaginable.
