Email Etiquette 101: To, From, CC, Bcc, RR, Subject

Editor’s Note: This blog is part of our Email Etiquette 101 series.

When addressing others in email correspondence, it’s essential to learn the differences between the To, From, CC, RR and Bcc fields. Adding a brief subject line is also helps when crafting an email. Learn a few tips in today’s Thursday Customer Service.

  • Only use CC when it’s essential for those being copied to know about the contents of an email. Do not overuse.
  • Don’t use Return Receipt (RR) in every single email. Overusing RR may come as intrusive, annoying, and can be declined by the recipient.
  • Include addresses in the To field for the intended recipients.
  • Include addresses in the CC field for those you are copying.
  • Make sure your name is displayed correctly in the From field.
  • Remove addresses from the To, CC, and Bcc field that doesn’t need to see your reply.
  • Always include a brief subject for your email. Not including one may flag your email as spam.
  • Think about your motives when adding addresses to the To, CC and Bcc fields. Use your discretion.
  • Never expose your friend’s or contact’s email addresses to strangers by listing them in the To field; use Bcc.
  • When using Bcc, make sure that you’re intentions are correct. Sending Bcc copies to others as a way of talking behind someone else’s back is inconsiderate.


Properly using email fields is crucial for effective communication. Whether you’re sending a message to a colleague or a long-lost friend, being mindful of your email’s structure ensures clarity, respect, and professionalism. As we journey through the Email Etiquette 101 series, it’s evident that the little details matter. Stay informed and make every email count!
