FWIW, some of us mark anything from constantcontact and similar companies as spam.
Also, if a business is sending me an email, I want it to come from them directly. I also want it to have the actual message content; I won't click on links to other sites, won't download pictures, and won't click on "If you're having trouble reading this..." links. Could be that I'm a Luddite about this, but the first email system I wrote from scratch was in 1982 and the second in 1987....
