> how customers can't turn off everything but confirmations
I'm a customer, I consider that opt out. You don't? I signed up for amazon, not their bullshit emails. That you consider the situation opt in shows they have you trained well.
Nice, ad hom, and I can't downvote your insulting comment! How about this: are you too lazy to uncheck a few check boxes? Because that's all it takes, and then you'll only get order and shipping confirmations.
