New research details the privacy implications of email tracking

About 30 percent of emails leak the recipient’s email address to one or more of these third parties when they are viewed. In the majority of cases, these leaks are intentional on the part of email senders, and further leaks occur if the recipient clicks links in emails.” How much of it is intentional? The paper said, “62 percent of the 100,963 leaks to third parties are intentional.” The privacy risk is even worse “if the leaked email address is associated with a tracking cookie, as it would be in many webmail clients.”
