I've seen a few posts here and I've had to laugh because there is absolutely no business sense to it. DO NOT BUY BULK EMAIL LISTS!!! Seriously most of these are not being used anymore, are from poor countries, are untargeted (thus will not convert), and most importantly they do not want your info...no matter how good the product you have. Ofcourse this all comes from the desire to cut corners "Why Build A List When I Can Get 134 Billion For $1!!!" Would you go out into the street handing out flyers to a thousand random people when there are a hundred outside your shop wanting to buy...or at least get product related info?
Yes, good point. I think a lot of these things exist and sell because the idea sounds good - and there are a lot of newbies who will give it a go, get burnt, and then only learn from the experience.
