By now you have probably read the other quick guides on how to add a popup and how to link a pop up from a button on your website.
You can also have a pop up show when a customer comes into a site, comes into a page, or is about the leave a site (so you set the pop up to appear based on a particular set of actions). Pretty Cool Huh!
To do this you will need to go to the inSites tab from the left hand navigation and the below steps will guide you through that process.
You can check how your pop up is performing over time by clicking on the wheel/settings icon in the inSite panel of your pop up. From the drop down you can select to de-active, delete or select analytics.
Go in and have a play around with the settings and the design.
