Adopted from the following insight shared by David Rock from his book Your Brain at Work is a masterclass on email writing skills.
1. Emails should contain as few words as possible.
2. Make it easy to see your central point at a glance, in one screen.
3. Never send an email that could emotionally affect another person unless it’s pure positive feedback.
4. Emotional issues must be discussed by phone; email should be used only to book a time for a call.
5. If you accidentally break rule number four, phone the person immediately, apologize, and discuss the issue by phone.
