"So you have somehow begged, borrowed or stolen an email list of 1000 users who you believe are interested in your new service."

If you had to scrounge around to find my name and other details, or otherwise do something besides ask me, I'm not interested, just so you know.

If I ever get an email with my name from a company I've never given information to, I look to see any indication of how they got it - and then delete that email.

I'm sure the people whose eyes are lighting up at this idea don't care that some of their targets won't like this bit of cyber-stalking. I can only hope those who use it get more resistance out of it than responses.
