I was never that good at writing but just putting some effort and caring about what you write down makes a huge difference. After you write an email or a document, read through the whole thing and edit. Is it obvious what I want to happen? Do I sound like a dick? The biggest improvement for me was to give more concrete answers. Like when someone asks you for a meeting, don't just say "yeah any time's fine", actually give a few dates and times that work for you. It also cuts down on the annoying back and forth of scheduling via email.
