[brian]

Social Media Marketing against the Email Marketing which is one is more effective and can get good convsersion?? Express your opinions regarding this.

According to me the social media is quite effective. Because its fast, free and also takes much more less effort. In the case of email marketing its slow as it takes a much effort and time to make a email list. I know that mail lists are much more less reliable but to me its social media.
