Get to the point (Tip 26)

[pioneer]

Be brief with your e-mail correspondence.

E-mail doesn’t always have to be long. If you need to communicate a lot of information, send it as an attachment or a formal letter, not as a text e-mail. Stick to the subject. If you have three topics or questions, consider sending three separate e-mails so you can sort and file the replies under the appropriate project file.
