Quite right on the unsolicited email contract. It'll never hold up. Most people assume Apple emails are spam anyway. Who would open them? I haven't read any of the Apple emails that come in for about 10 years. I get 10 or 20 a day from Apple, all disregarded by me (because their opt-out never works). You can't just email someone and say here's my terms and you are stuck with them. Doesn't work, won't hold up in court.
By the way, you owe me 2 million dollars unless you opt out by 6 am (West Coast Time) tomorrow in writing with a notarized signature... unfortunately, the notary's office doesn't open until 10 am... oh well, waiting for my check in the mail
This is one tactic Apple will be retracting before too long... It'll never stand.
