The parent customer and its sub-customers are treated as different profiles. So, you'll need to update their email addresses individually.
Also, I encourage sending feedback to our engineers. This way, they can consider your idea about automatically updating the sub-customers' email addresses based on the parent customer's email address.

This is one of the things that I 100% hate about QB. It is 2020 and you cannot change the contact info for more than one entry at a time. Seriously, why is this even on a computer.
Over 5 years later and this still has not been fixed! The project email is tied to the first invoice that was sent on that project. If we update the customer email it won't update the project... I can't believe this is still a problem.
I recommend contacting our Customer Support Team to get added to a list of affected users. I've discovered an investigation (INV-103601) that we have open that's associated with your problem.
