The words unsolicited e-mail should be more than enough to make you worry about being scammed.

Why don't you name the recruiter? Are you scared he/she might suddenly become aware that we all know that he/she is sending out "unsolicited email" and then he/she takes his/her revenge by sending you to a crappy training school?

Best advice is to delete it and then take the time read the post in the "resources" above this forum before you go and make a mistake.

But then again as you don't name the "spammer" (call me cynical) but this thread looks like becoming one big advertising stunt with a few people recommending using an unknown recruiter who send out unsolicited emails.
