Editors of newsletters always need good content, particularly if their newsletter is published often. So, a few of them will allow you to publish your article for nothing in return for offering them the work. Learn how many subscribers each newsletter has–in general, the most noteworthy and significant ones will publish this info. Send your article to the one with the highest number of customers first and continue down the list. BUT make sure that you wait a couple of days in between each submission so you avoid having the same article published by different newsletters on the same day, causing embarrassment to them and possible denial of any future articles from you.
When you have finished sending the manuscript to all the newsletters on your list, then send it to lists (like IdeaMarketers.com, for example) that hold articles that other newsletters can send to their customers. Remember that the key to getting the most impressive results with this in terms of free internet site traffic is to scribble quality content. You don’t have to be a pro writer but your article should be freed from grammatical and spelling mistakes, and maybe more importantly, offer valuable info that answers the questions or deciphers the issues of your target readers.
