Why is there an error when I click on unsubscribe?

There are a few reasons why clicking on the unsubscribe link can result in an error message. Your email program modified the link. Your email program blocked the link. Your firewall settings modified the link. When a link is modified or blocked by either your email program or firewall, the unsubscribe request will result in an error because we will not have your correct information to unsubscribe you.
