Hi. I doubt the e-mail you received was anything more than a marketing ploy. Especially if you are not a member of their service. However, the numbers following you around are probably significant. 27 appearing in the e-mail is probably just another instance of the universe (or however you want to put it) trying to tell you something. I suppose, they could be trying to tell you that "something will happen that will change your life forever" whether on the 27th or not, but I really can't say one way or the other.
There are numbers that follow me sometimes, too, though. And, like you I posted a question about it in the forums and someone gave me this great answer. She wrote all this stuff about numerology and I refer to the post every once in a while when I need to know what a number means. I'll see if I can point you to the post in my next post.
