This sitting by the computer and refreshing the Dashboard every few minutes ... is crazy.
8 AM, no email and no change on my dashboard, so, is that just Not-Yet, or a Bug-on-the-Windshield?
So easy for them to put up an order-date (if they are organized enough to know it), or an "order-tomorrow" (assuming they know what emails they will be sending out the very next morning).
I suggest continuing to call CS to ask if you will be in the "tomorrow" group, explaining that if you know the (upcoming-soon) date, you could quit accessing their Dashboard server hundreds of times a day. That would lighten their server load by a factor of 50 or 100, so it could do its job better.
Explain that you cannot depend upon getting one email ... it could get "lost" by your provider.
Ask if your Account has an "order-activation date" field in their Dashboard database.
Ask when the decision is made that determines what emails will be sent out the very next day.
Hopefully, after a while, they will get tired of handling the same questions and "update" the Dashboard to be more useful to us.
