How it can be beneficial for online business?

hi,I want a software to get the email address of the website automatically .
such as seach by key words ‘outdoor sports’ , I want the email addresses are listed along with the searching results.
Please give me some leads.thank you

What is it for and who are the people that can greatly benefit for it?

We have never used mass email marketing before but are giving it very serious consideration now. We can get a company to do it for us or we can simply buy databases and an application and do it ourselves. But we’re wondering whether our ISP might get a bit annoyed if we send out millions of emails? Thanks
The application enables us to bypass our ISP’s SMTP server (if that helps?!)

Thanks for viewing my question.
I am running a forum namely webmastertalk.in since a long time, around 2 years and it was the best forum for webmasters at that time but due to little dissconnection I losed my members and I am back again, its running , going good but I want more members, how can I promotes it. Please help me and do join my forum. Thanks Alot!
The reason was my dissconnection and before this I never did email marketing. I thought to email marketing like extracting some address from targetted niche and introducing about our site. Well as you said imisdro , I am doing the same and told the members about the site is up and running again but I was searching some more ways – Thanks for response.
