Same way legal departments dress up what are more or less informal requests in high language and good production values.

Old manager coined it "the power is in the template", big difference in response rate between an informal handwritten request & a proper looking 'official' request to comply.

My go to as a freelancer was to buy a nice template (spend $50, it's worth it..) and customize it appropriately. You want something approaching "savvy yet professional" most of the time.
