People often wonder why it is so important to their internet marketing business to have a successful and responsive mailing list. Those in the know, however, understand that such a mailing list is the biggest asset that any online business could ever have.A responsive mailing list equates to guaranteed long-term buyers and customers, which in itself is the equivalent of money in your bank account.It is no coincidence that the most successful internet marketers, the guys and girls who can genuinely make over $1 million in gross returns in a 24-hour period, have all built huge mailing lists. In fact, some of these super successful marketers have even gone so far as paying people on an individual basis to join their lists, and that fact alone must tell you just how valuable such a mailing list can be.Of course, once you have added somebody’s name to your mailing list, then you must have something of value to send to them. For most online marketers, this will be a newsletter or e-zine that they will send out to their subscribers on a regular basis. It is an important skill to learn to create your own successful newsletter. This will give your subscribers a regular supply of information that you already know they will be interested in. By doing this, you will establish the fact that you are trustworthy and credible and thereby give your subscribers every reason to do business with you in the future.You should not underestimate, however, the number of marketers who are trying to do exactly the same as you are. There are literally thousands of newsletters and e-zines out there in the marketplace, and it is therefore an extremely competitive area of online business.You may read many guides and manuals to e-mail marketing and list building that indicate that you should in some way tried to ‘stand out from the crowd’. Unfortunately, such a thing is nearly impossible!What you can do, however, is make sure that everything you send to your mailing list members has true and genuine value. In this way, you gradually turn your subscribers into your own ‘fan club’ and ensure that they will stick with you even when offered newsletters and e-zines by other marketers.As you will discover, there are many ways that you can make money from your newsletter, but, in order to this, you have to go beyond the regular average product endorsement that most marketers use.Of course, such product endorsements can be excellent money spinners, but there are many other ways that revenues can be generated as long as you have a responsive mailing list.Even your newsletter offers other money making opportunities to you. For example, once you have reached a decent circulation level, with a few thousand ‘copies’ being sent out every time, then you can sell advertising space to other non-competing marketers in your market niche. This is something that we will look at in more detail later.However, the more people that you can send your newsletter to, the more money you will be able to charge for such advertising. It is therefore critical that you continually build your list using every tactic and technique available to you. There are many different list building tactics which you will read of in this manual, and quite a few of them are not going to cost you any money. This means that even as a relative newcomer to the world of online business and internet marketing, there is nothing that should be allowed to hold you back from building your list in the proper manner right from the outset.You may have noticed that I have already mentioned that your list has to be responsive. This means that it is absolutely necessary that you give your subscribers what they need and want, rather than what you want send them. By doing this, you will turn many of the individual subscribers on your list into repeat customers, and these are the best and most important asset that your business will ever have.
