You have to have be familiar with email marketing. If you're not, you should be as this has proven to be the most effective form of advertising available in my opinion. These leads are single optin and need to be double opt-in or "confirmed" according to the canned SPAM act. So, it does take work to get your system setup, but it was well worth the time and effort.  Although I received excellent results using this service, I am getting feedback that these leads are fair to poor.  But remember, they do offer a trial membership.  

Very easy to join and navigate their site, the graphics are particularly eye catching. This site is recommended so give it a try. If you intend to use this service remember you will need an email blaster.
