One of biggest obstacles to building a good sized opt in list is drop out rate. Sometimes it seems subscribers are leaving as fast as they are joining. This slows down overall growth rate.

This can make whole process of list building frustrating. For this reason many list builders get into a pattern of starting and quitting which can further slow down overall list building process.

Unfortunately most of strategies for list building suffer from a negative quality. The conventional wisdom still has Internet marketers using ebooks, software, e-courses, auto responder series and such to build and keep their lists.

The problem is that at least as far as building and keeping mailing lists ebooks and software have become practically worthless. Even highest quality most information packed ebook has very little value.

Many marketers don't want to hear this but it is absolutely true. First, information that it gives you is almost always something that we've heard or read before.

How many different ways can an author repeat same things. How many times have you heard that it is important to build lists for instance? Or to collect email addresses before sending prospects to your affiliate page?

What about writing articles for free traffic or tracking your ads so you know what works and what doesn't? Most secrets are not really secret anymore so ebooks tend to be just reworded and recycled information.

Secondly, once ebook has been read or e-course is finished what's to keep your subscriber from un-subscribing? You have to constantly try to keep subscribers interest. This is very hard to do because we are constantly bombarded with more and more information from different sources.
