When you get to a point in your business that you start collecting email address making different lists might be a smart idea from the beginning instead of down the road when your list is so large you have a hard time even looking at it. Dividing up your email marketing list in different characteristics will allow you to really target your email marketing campaigns down the road.
There are many ways you can divide up the list.
Inquiries: Anyone that has ever inquired about your services and products in one list can allow you to send special first sign up or product purchase offers to get that person to make a purchase or start up another purchasing conversation.
Products: You could separate your list into purchasing habits and which products people buy. This will allow you to market specific products depending on purchasing habits of your current customers.
Geographically: Depending on what type of products you sell and where if you notice that a certain number of people are buying a specific product in a geographical area you can then market products related to that area that might likely use or enjoy.
These are just a few examples of what you can do with your list in order to maximize your email marketing efforts. If you are a business that collects emails frequently this will be very important to do early in the game.
