Hi Can-I-Ask-You-a-Question,
Here's some information we think might be helpful for this issue:
"To stop receiving newsletters, choose File > Manage Notifications & Email, then turn off Apple News Newsletter. In the U.S., click Manage Newsletters, then unsubscribe from each newsletter you no longer want to receive.
You can also opt in or out of the newsletters using Apple ID settings or on the Apple ID website (see the Apple Support article Manage emails that you receive from Apple)."
You can read the full resource here: Receive or stop receiving Apple News newsletters - Apple Support
We hope this resolves things for you.
Take care.
