Way before bots/LLM, I disciplined myself (most of the time) to write email with "in brief" at the top, followed by "Details".

"In brief: Can you bring a dozen brownies to the noon lunch tomorrow?

Details: Dessert plans fell through. Your brownies are the best, and you owe me..."

This structure is liberating for me. I can distill what I want/need into something brief and even brusque, knowing that people will read on if the need justification. It also makes me clarify what I want. Probably not appropriate if I'm too far down the totem pole from the addressee.
