In Ultra Course View, users without a configured email address are able to attempt sending emails to instructors when messaging is disabled. However, no validation or warning is presented, and the email is not delivered.

In contrast, Original Course View correctly prevents this action and displays a warning message:

"The sender's email address wasn't specified or is invalid. Edit Personal Information and set email address."

This results in inconsistent behaviour between course experiences and leads to silent email failure in Ultra.

Observed Behavior:

No warning is displayed and the email is not sent to the instructor.

Expected Behavior:

Message should be sent using the designated admin address.
