If you have been an internet marketer, or had any type of online home based business, for more than a few days, then you will no doubt have heard someone say, "if you want to make money online, you have to build an opt-in list."Take that advice very seriously, because it’s true! It took me a long time to finally let the list building advice sink in, so I didn’t start doing it until I had my home business for quite a while. However, once I started building my list, I realized just how important .
