How do I find e-mail addresses to promote my affiliate business via the net?

I need to find active e-mail addresses to send them my promotional items for my affiliate business. Can anyone tell me how?

use yellow pages or white pages on internet like

http://www.yellowpages.com/

http://www.whitepages.com/

for your region, search businesses (using business type in search query ) that may be interested in those promo items and send them via email (if email listed for that businesses)
