Systems and methods for providing authentication verification for a correspondence and other messages are disclosed. A link, such as a uniform resource locator (URL) link, is placed in a correspondence and sent to a user. When the user follows the link, a list of personal transaction data from the user's credit card or other financial account is presented. Because the personal transaction data is substantially private to user and his or her financial institution and card servicing company and not known to the public, the recipient can be assured that the message truly came from the financial institution or the card servicing company and not from a phisher.
