You will want to build a lasting relationship with the people on your list. In order to make huge profits with a small list, one with fewer than a thousand names, you must remember why they came to you in the first place. This may be the most important thing to keep in mind when you begin to connect with them and to promote your own and affiliate products to them. These prospects are much more than just numbers on your list; they are the people that will determine if you are successful or not in your quest to build an online empire.
Think about this as you write your emails, choose the products and courses you will promote, and respond to your prospects individually. Straying off the path and offering them off topic information will not serve you well over time.
Writing an email to your list should be a personal communication between you and each of them. What I mean by this is that you need to write as though you were writing to just one person. The highest compliment you will ever receive is when someone thinks you have written only to them when you send out an email to your entire list. This is an art, so do not be surprised if it takes months, or even years, before this happens to you. Once you get into the rhythm of emailing your list, this will become a regular occurence.
