I suggest a study program in social signaling, but I'll summarize the relevant part:
People of unknown status must provide a signal that their status is appropriate enough to warrant respect and attention: if you're taking your Valentine's date to a Michelin 3-star restaurant, you wear your best clothes.
People of known high status have the capability of signaling their status in a seemingly perverse way: by countersignaling. When a movie star shows up to a Michelin 3-star restaurant, he wears jeans and a faded t-shirt to show that he's high-status enough to break convention there.
tl;dr: C-level execs backed by the strongest VCs have earned the right to write informally and still be taken seriously. Most of us have not.
