Use e-mail to transmit factual information, not to criticize a colleague or communicate a
sensitive message. In writing e-mails, make sure the subject line is simple, descriptive and
attracts the reader’s attention. When making a request, use an action verb in the subject
line, such as “Provide input on slides”.
E-mail is a “lean” channel that does not allow for quick feedback, or the ability
to read non-verbal cues. Therefore, it is best for non-emotional, objective messages. The
subject line is the gateway to further communication. In the case of making a request, users
are more likely to open e-mail requesting specific action.
