I did a duckduckgo search pertaining to CIT, and one of the first page hits was this:
http://tracking.citibank.com/ex/splash. ... 13E6834C5D
Odd, I thought. To see what would happen, I clicked on the unsubscribe link, and it gave "Your email address, , has been opted out of receiving the Citibank Customer Updates & News e-mail from Citibank retail banking."
So, after initial concern, it appears null was unsubscribed. Are email 'templates' like this normally found via normal searching of the interwebz? Just curious. This is the first time that I can recall coming across something like this via search results.
