Email? Is there a text message option? The last thing I want is my workaholic DH to open his email while we are at the parks

Did you get a message when Star Tours came back up?
I don't think there is an option for text messaging rather than emails. And no, we did not get a message telling us when Star Tours was again operational.
These email notifications work fine for guests that have a wi-fi enabled device with them in the Parks. I consider this feature gives a slight advantage to guests that have smartphones, iPads, iTouches, etc., compared to those that don't use such devices in the Parks. In our particular situation, we don't have a smartphone so we weren't even aware that we had received an email about Star Tours temporarily being down. It wasn't until later that evening when we got back to our villa that we read the email. I kept a copy of the email -- that is the reason I can remember all the specifics about the notification.
Although we couldn't take advantage of the "instant" notification while at the Park, we quickly learned about our options by taking to the CMs. A Star Tours CM directed us to another "FastPass+" CM who was right there at the Star Tours attraction. The FastPass+ CM had an iPad and he quickly explained our options to us, basically telling us everything that was contained in the email.
In November, these FastPass+ CMs were scattered throughout the Parks. Some were manning the FastPass+ kiosks, but there were many others who were near major attractions. The FastPass+ CMs carried iPads, which they could use to access your FastPass+ selections. They could make changes, or book selections if you hadn't made them yet.
The FastPass+ CMs were easy to spot. They wore a teal shirt or a dark blue shirt with a green Mickey Head on the chest, and they all had iPads. The teal shirted CMs could help guests with FastPass+. The blue shirted CMs had the capacity to help manage anything to do with MagicBands and
MDE, as well as FastPass+. Here is a photo of one of the teal shirted FastPass+ CMs:
