Alysia,
I know this is off topic, but in your response above you mention "bulk emails" and "unsubscribing". Well, I`m sorry, but you have fallen for one of the spammers oldest tricks. You should NEVER hit the unsubscribe button of any unsolicited emails you receive, as this merely informs the sender that the address to which the email was sent is "live", and, without a shadow of doubt, you will receive even more spam. Just totally ignore unsolicited emails.
I`m not sure why you are delving into your "bulk" email folder to find "unsubscribe" buttons, as your email filtering software has already identified them as spam.
Finally, I believe the messages you are trying to read something into, are all spam. Sorry.
Regards,
roger.
