How often have you seen those words in an e-mail? I just saw them again in the subscription confirmation for a business blog. Over the last few years, I have subscribed and unsubscribed to literally hundreds of things like this, and so have you. If there is some control freak out there who actually keeps and files all this stuff, they should get some kind of award.
We could give another award to the folks who have time to read all the legalese they have agreed to. As one executive I met put it recently, "I don't have time to be a responsible citizen [and read all these agreements]".
We need to ruthlessly examine customer communications for this kind of nonsense and surgically remove it whenever we find it. And forget that "everyone does it" -- you know that never washed with your mother, and it won't wash with your customers either.
We all have limited band-width: save your customer's attention for meaningful messages.
