I never used or heard anything about Yipit and have no idea who these guys are. I also would like to know where did they get my email address. About two weeks ago I received a message from them and thought it was just a spam. Next day I received another messages and they continue to spam my mail! I went to their website and tried to contact customer service. I wanted to ask them to stop annoying me, but they did not reply! I want them to stop sending me messages!!
