Here are some guidelines to enable you to write e-mail like the Fortune 500 pros. Before writing, jot down your main points or purpose. Decide what's most important and lead with that, in the first paragraph if possible. Don't leave important information for the second screen. Readers hate to scroll and may not get past the first screen.
Readers use the subject line to perform e-mail triage.
A good subject line announces that it's relevant or urgent. A vague subject line invites the reader to ignore or delete the message. Don't leave the reader wondering why you sent the e-mail and what you want. Convey the desired action clearly, boldly and early in the message. Make your paragraphs short, use vertical bulleted lists to condense information, and add white space for visual relief.
