Hooper, if you had to haul 1000 envelopes a day out of your mailbox, and dispose of them each day, you would get tired of it. What would happen if half of them were of a sexual nature? Now you can't let your kids or anyone else empty your mailbox for you. What happens if you lose important mails because you don't have time to look through the 1000 pieces to find the one good one?
Your arguement isn't very strong - it is only strong when you are talking 10 pieces of spam email or 10 pieces of spam snail mail. Up that to 1000 pieces a day, and suddenly IT SUCKS!
Your two categories are funny. You forgot that the type B mailer reuses his list over and over again, without concern for bounces or cancels. He might mail that same list 20 times a day. You get a few hundred of those people going, and suddenly IT SUCKS!
Then again, hard to argue with you, you were the one with 30 emails to every person that signed up to your sites, right?
