Pixel tags (which are also known as web beacons and clear GIFs) are used on our websites and HTML-formatted emails to track the actions of users on our websites. Unlike cookies, which are stored on the hard drive of your computer or mobile device by a website, pixel tags are embedded invisibly on webpages or within HTML-formatted emails. Pixel tags measure the success of our marketing campaigns and compile statistics about usage of our websites or engagement with email notices so that we can manage our content more effectively.
