Hi calvynlee

I was also looking to increase traffic on my website and I choose email advertising.

I googled 'opt-in email advertising' and tested each week the companies I found there (used the first ones listed on that page) and got a lot of traffic, but the sales did not increase too much.

Acceptable results I got for taketheinternetback.com where I paid 1000 emails for $15 and got not only traffic, but also some sales.

I searched alexa.com for stats, and it seems that most of the traffic on this website is US based, so it would make sense to use it in my case.

So ... For the moment I stick with taketheinternetback.com.
