I agree. I don't care that it's one email: I didn't ask to be mailed their info, they clearly got my name from someone's list, and I have added them to my "junk email" list. That is spam in my book.

I had heard about this conference through word of mouth and was considering it. Now I am not sure (yes, I feel THAT strongly about getting unsolicited email).
