There is an interesting thing about marketing, it is always changing. We recently received an inquiry from someone who wanted me to do email marketing to a list they were going to purchase on behalf of a client they had. Our heart sank. Let me start by saying, if you are buying lists to market to your audience, stop. Stop right now. Today, there is no faster way to get blacklisted on Google than the market to an email list you do not have permission to contact.
