Hmmmm... I've not found that email, and I'm a (for Windows) RSD licensee.
BTW, my view of the .../myproducts page shows "Responsive Email Designer for Business 1.2" in the both the "Software you do not own" and the "Software you own" categories. Could CC's product licensee database be out of sync? Could that explain my not receiving (and so not seeing) the RCS pre-release offer message? Or did it die in the Spam filter? (I will be looking at that possibility, too.)

Yes, I looked just like that in 1962.
