If you are new to Internet Marketing you probably heard people suggest you build a list or capture leads. If you aren't quite sure what this means this you came to the right place. I'll detail exactly what this means and what it'll mean to you for your bottom line. An internet marketing list is a list of people who opted in to be added to their email list. This email list normally consists of your email address and your full name or just your first name. This list is again normally of the same niche, so people may build a list for the internet marketing niche or a dog training niche.
