I run a weekly email list with 800+ responsive readers. I have an opening for an article and ad on the next 3 newsletters. The best response is from articles. The newsletter is aimed at opportunity seekers so ads from affiliates, business opportunities, and network marketing areas generally work well. Recently over a couple of weeks articles and ads placed over 50 people in an MLM. We normally charge $15 for a side ad and $35 for a pre-written article. But I will offer a special of $35. AND you may have this virtually free. PM me for details.
