I have two young daughters at home who love to play with blocks. My four-year-old knows that if she builds a strong foundation, she can add blocks to her tower and make it taller and taller. My one-year-old has not yet learned this lesson, and her towers continually fall down. The same is true for email marketing. Without a good foundation and a strong plan, your program will fall apart no matter how hard you try. One of the key components to a strong foundation is building a sound contact plan.
