If you run a webmaster forum or similar webmaster site and have an opt-in mailing list of at least 50K+ webmasters, I would like to buy a solo email campaign to your members. Please PM me site details, subscribers / users and definitely don't forget to include a price.
I am a free directory owner.. I send around 200 mails/day to submitters/webmasters. I can attach your ad.. PM if interested with a price.
