One of the things that the introduction of blogs has done is to cause an exodus of sorts from email newsletters or ezines to online publishers simply publishing the information on their blogs.

It is not too difficult to realize why online publishers embraced blogs so quickly and enthusiastically. Actually the SPAM monster appeared to be slowly squeezing the life out of their online business. To meet the SPAM challenge most ISPs have set up SPAM filters that are so powerful that they quite often filter out mail that has been requested, especially mail of the massive opt-in kind. This has meant an increasing number of bounces and undeliverable mail.

With the arrival of blogs there was an easy way out of all this anxiety. Ezines could easily be posted on blogs and no ISP SPAM filter would touch it. And what is more the email aspect of feedback was not lost because readers could easily post a comment at the blog. The huge advantage over email here was that one could see another readers comment and quickly support or disagree with it. Blogs have actually revolutionized publishing the way no other tool has in the history of mankind.

So have blogs made email newsletters and opt-in email lists obsolete? The answer is a firm NO. Nothing would be further from the truth. Even when an online publisher delivers their weekly or daily content at a blog, what is the best way of sustaining and growing traffic to the blog?

Actually even with a website, there is no other more effective way of sustaining high traffic than by harvesting email addresses. This is done by offering and email newsletter or an email course of sorts. This builds up a valuable opt-in email list that you can use again and again to direct traffic to your site. You can even sell them something. As internet marketing experts often point out, the money is in the list.

This is the reason why experts advice affiliates to set up their own sites or blogs to play a key role in their efforts to market their affiliate site. This is simply because it is a huge waste to drive so much traffic to your affiliate site and end up having only a tiny fraction signing up for your affiliate program. By driving traffic through your own site, you have an opportunity to harvest emails and build up a huge, valuable targeted opt-in email list that you can still market the very same affiliate program to, later. In fact research has clearly shown that most people buy only after several repeated encounters of the same product or service.

Even with the introduction of the extremely useful blogging tool and the change of business models by many online publishers, opt-in email lists still remain the most valuable online marketing tool.
