Web beacons used on pages or in emails allow us to see how successful an article has been, or whether an email message was successfully delivered and read in a marketing campaign. Web beacons are also used to verify any clicks through to links or advertisements contained in emails. We may use this information to help us identify which emails are more interesting to you and to inform advertisers how many customers have clicked on their adverts (the information shared with advertisers is aggregated and does not identify you individually).</p>
