We and our service providers may also use various common Internet tools such as 'pixel tags,' ‘action tags,’ ‘web beacons,’ ‘.gif tags,’ 'JavaScript' or similar technologies (together, "Tools") in connection with Site pages and email messages in certain formats to, among other things, track the actions of Site users and email recipients, to determine the success of marketing campaigns and to compile statistics about Site usage and response rates. Tools allow us to count users who have visited certain pages of the Site, to deliver services, and to help determine the effectiveness of promotional or advertising campaigns. When used in email messages in certain formats, Tools can tell the sender whether and when the email has been opened.
