Shorter emails are better 99% of the time. No one's going to read a long email, so you should keep your email to just the most important points. Expanding out these points to a longer email is just a waste of time for everyone involved.

My email inbox is already filled with a bunch of automated emails that provide me no info and waste my time. The last thing I want is an AI tool that makes it easier to generate even more crap.

Definitely. Also, another thing that wastes time is when requests don't provide the necessary context for people to understand what's being asked for and why, causing them to spend hours on the wrong thing. Or when the nuance is left out of a nuanced good idea causing it to get misinterpreted and pattern-matched to a similar-sounding-but-different bad idea, causes endless back-and-forth misunderstandings and escalation.

Emails sent company-wide need to be especially short, because so many person-hours are spent reading them. Also, they need to provide the most background context to be understood, because most of those readers won't already share the common ground to understand a compressed message, increasing the risk of miscommunication.

This is why messages need to be extremely brief, but also not.
