If you find that you can't write an email that's less than half a page long, then email isn't the best way to communicate this information. Instead, call the person and talk to them directly.

In writing, your goal is to be clear and direct. If your reader has to use Google to decipher what you're trying to say, they're going to feel alienated and annoyed.

Mark Twain once said, "Don't use a five-dollar word when a fifty-cent word will do." Avoid the temptation to use flowery, pretentious words to sound smarter. Stick with the fifty-cent words.
