Can someone please tell me if spamming EVERYONE about Cialis, Viagra, Rolex watches, anything to do with Nigeria, lotto winnings, etc. is effective marketing? I get these all the time and regularly erase them. Does anyone respond to them? Please let me know. I would think the amount of time and energy expended to send these things out could be put to better use. I guess it is cheaper than direct mail. Let me know your thoughts.
