Electronic communication is constantly changing. Email is great for fast and effective communication, but basic rules for clarity, courtesy, and respect should still be kept in mind. While email is certainly a more informal form of communication, here are some tips for effective and civil email communication.
Don't send an email in haste when you are upset. If you are thinking of addressing a workplace problem via email, give it a few days. Allow yourself some time to calm down and think things over. You can't take back that angry email.
Be sure to include an informative and poignant subject line. Never send an email with "no subject" in the subject line.
While spellcheck is a great tool, always read your emails over once or twice for grammar, spelling and word choice. Email is not an excuse for misspellings, grammatical errors, or punctual mistakes.
Be aware of usage of all caps, emoticons, and text message abbreviation. Using all capital letters tends to convey to the reader that you are shouting at them and tends to be harder to read. Also be aware that in the absence of facial expressions or tone of voice, interpretation defaults to the negative.
While there is no doubt that email is more informal than a typed letter, salutations and closings are still important. When composing email to senior management always use a more formal greeting. When in doubt, defer to the formal. For example, use Mr. or Ms., hello versus hi, or Elizabeth versus Liz. When communicating with senior management you should also end the email with a formal sign-off as well.
