I never quite understood why I should be building my email marketing list until the last few weeks. I started to understand why people do it after I went to a blogging conference. There was a class about email marketing lists and I decided it would be a good one for me to go to. I learned a lot about email lists, how they are good because you are able to own them and growing them should be a priority.
