I am interested in promoting my website and services to a very targeted niche market: screenwriters and amateurs who write screenplays. But I am having a hard time finding a mailing list or opt-in emailing list for this specific group to promote to. I have checked with some of the big mailing list companies but my niche is just that-a niche. I already promote my site through Google adwords but now want to send direct mail or email.
Does anyone have any suggestions for finding lists for such a small targeted group? Thanks.

I am marketing a product to seniors of a specific area defined by zip code or city. Where can I find a mailing list?

I was in a site a few days ago that said you can get upto 5 free zip codes for telemarketing phone numbers, now I cant find it
