Cheat Sheet

  1. Clear and Specific Subject Lines -

    Professional email etiquette starts with a concise subject line of 5 - 7 words that reflects the email's purpose. According to Purdue OWL, clear subjects improve open rates and prevent misunderstanding - e.g., "Q3 Budget Review: Feedback Needed by 5/15." When tackling an email etiquette quiz question on subject lines, use the "5W" rule (Who, What, When, Where, Why) as a quick mnemonic for clarity.

  2. Appropriate Greetings and Closings -

    Business email etiquette best practices recommend using formal salutations like "Hello Dr. Smith" and closings such as "Best regards." Harvard Business Review notes that matching tone to your audience builds rapport and respect, while overly casual openings ("Hey team!") risk seeming unprofessional. Remember the G-R mnemonic: Greet, Relate, and Respect.

  3. Structured, Concise Content -

    Professional emails should follow the "KISS" principle (Keep It Short & Simple) and a clear structure: a brief opening, key points in bullets, and a closing call to action. Yale University's communications office shows that structuring emails in 3 parts (Situation, Action, Outcome) streamlines comprehension. Use numbers or bullet lists to highlight critical information.

  4. Respectful Tone and Formality -

    Professional email etiquette emphasizes respectful language, avoiding ALL CAPS (perceived as shouting) and slang. According to a study by the University of Chicago, a moderate level of formality and positive tone reduces misinterpretation. If you encounter "which of the following is not considered appropriate email etiquette" on your quiz, selecting ALL CAPS or slang will be the correct choice.

  5. Proofreading, Attachments, and Reply-All Etiquette -

    Email etiquette best practices dictate always proofreading for typos and grammar errors (Grammarly or university writing centers can help) and confirming attachments before hitting send. Industry data shows mis-sent "Reply All" messages disrupt workflows and breach confidentiality. Use the simple trick "Attach Before Text" to avoid missing files.
