Obfuscated emails on the Unsubscribe page
We changed the behavior of the unsubscribe merge tag to obfuscate the email address of the person who clicked the link. Instead of showing the entire address, the
md_email parameter now displays the address as something like x****@x***.*** .
Previously, if a customer clicked an unsubscribe link, their email address was displayed on the Unsubscribe page in full. By obfuscating the email address, this change provides better security.
