Tell that to apple mail. Makes no sense how an app seemingly unchanged since the tiger days when I started using it could still be as performant as it always was on far better hardware. In fact I frequently find it to be the culprit when I wonder what the hell could be spinning my fans on this m3 pro just churning over the database.

Iphone version is arguably worse because it also has performance issues but doesn’t support inbox rules. Then again those inbox rules often fail to filter emails anyhow.
