Email Etiquette

Email Etiquette ✉️

Professional communication is a key skill in this course — and beyond. These guidelines apply when emailing instructors, TAs, project partners, or external stakeholders.

Do's ✅

  • Use a clear, specific subject line — include the course number (CSE120) and topic.
    Good: CSE120 – Question about Lab 4.3 test expectations
    Bad: Question or Help
  • Address the recipient properly — "Dear Prof. Chandrasekhar," or "Hi Michael," depending on context.
  • State your purpose upfront — first sentence explains why you're writing.
  • Be concise — respect the reader's time.
  • Include relevant details — your lab section, team number, links to relevant materials.
  • Proofread — read before sending.
  • Allow 48 hours for a response (excluding weekends/holidays).

Don'ts ❌

  • Don't use text-speak or emojis in formal emails.
  • Don't demand an immediate response.
  • Don't ask questions already answered in the syllabus or assignment description.
  • Don't submit assignments via email — they won't be accepted.
