First off, shoving AI in everything continues to be wildly stupid and against the wishes of users. Not to mention an ecological nightmare.
Secondly, if someone changes the NAME on their account, it should default to changing the name in their sent email headers. It's insane that you have to dig into the settings for this, and you have no reason to believe that it WOULDNT do this. I used this mail to try and be anonymous, and you made me send an "anonymous" email with my full first and last name in the header. Terrible design.
