I'm always amazed when I receive an obviously canned email asking for a link to a site. Or a spam message from a show-promoter trying to find new vendors for an event. I know I did not sign up for a list from them, therefore I am being spammed by the very people I could help with some exposure. Remember, that if you send unsolicited canned emails to people, you are hurting your online marketing efforts. Many people will resent the intrusion and if you continually send large amounts of people spam, you may even be breaking the law!
