With Wise Popup you have a web utility to create professional Popup windows, using DHTML (Dynamic HTML) design, which makes these popups not exactly in windows but in layers (which makes them unblockable).
From the Wise Popup program you can manage the time intervals for each popup that will be opened, make sure that a certain popup will only open for each independent session (that is, for different users), decide if it is activated when the user enters the web or when you leave it, etc.
Wise Popup is a tool to keep in mind, if you work in the world of web programming.
You can free download Wise Popup 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
