Using emails is one the most powerful ways of marketing, especially if you have a targeted list of subscribers. It often takes marketers a long time to realise how important building your list is. You should be doing it right from the beginning of starting your business.

1 Your most valuable asset. Nothing beats a targeted list for producing on-going sales. With a good list you can almost guarantee sales and therefore a regular income with the right offers. This is why double opt-in is so important. Once someone has filled in a sign up form, they then have to confirm that they want to join that particular list. This ensures their interest and commitment to getting the information that was advertised. Such subscribers are more likely to remain on the list and to be responsive to offers because of their trust in the marketer.

2 Availability. Your list is always available. In fact, it grows in knowledge and understanding with the business. This means loyal customers who can be offered fresh deals on a regular basis. It's a win-win because they get the service and information they want and you get their loyalty and the profits.

3 Bigger the better. As a general rule the bigger the list the more sales you'll probably make. This is because they're double opt-in and are looking for products from you. The usual financial assessment is that each member of the list is worth $1 per month. Thus, one thousand members means about one thousand dollars a month.

4 Core of your business. Your business values should be conveyed to your list. Those who don't agree can obviously leave. But that will leave you more clearly with those who are committed to what you have to offer. Therefore, they should be supported in the best possible way.
