I don't see why the value of the Reply-To address would affect that.

  Because you can also unsubscribe by replying "unsubscribe if there is no link. Part of CAN-SPAM.

    CAN-SPAM likely doesn't apply to the message in the first place, but even if it did it does not specifically require that you can unsubscribe by replying. That's just an example of one method they can provide.
    • somid3 10y ago
      True. I was testing. They provide no method to unsubscribe.

  Transaction would seem to imply a two way communication. trans·ac·tion an exchange or interaction between people.

  I think you're correct--someone else in the comments pasted the FTC's definition of "transactional," and the transaction in question may be an already initiated commercial transaction, not an interactive transaction between two parties on email like I had thought.
