Well CEO can do it because she is a CEO. If any employee would use this method it'd be considered poor communication and the person considered as lazy and incompetent.
Put the most important bits first. Be as brief as possible while still being courteous. Recap at the end, including specifically calling out necessary next steps.
My experience is that people often tend to include detail that is only of interest to them, often because they're not certain their request will stand on its own.
Only spend time to add information you're certain is necessary (and I know I often err on this); if your manager needs more info to make a decision, they'll ask.
People will often be grateful if you spare them the details of things they don't need the details of, as long as you can show you've done your work if/when they do ask. The more they can trust you to have data to back up what you ask for, the less they'll actually ask.
