A link, as seen in an email, will always take you to exactly where the text says it will.

False - What you see in the text of the mail is not the actual URL (address), but just an anchor. This is called a hyperlink. It is the underlying URL that decides which site or page you will be taken to when you click on the link. So if the underlying URL changes, even if the text is the same, you will be directed to the address of that link.
