  • Email messaging abbreviations

These abbreviations are used by email clients or can help you automate inbound correspondence.

CC/BCC - Carbon Copy/Blind Carbon Copy. These two are the ways of sending copies of an email to additional people. With  CC, it is possible to see who else has received the message. And BCC does not allow to do that.

EOM - End of Message. This is one of the email subject abbreviations. Senders often use it to save recipients the trouble of opening an email unnecessarily. For example, if you want to leave the body of the email blank, you can use the EOM acronym in your subject line in the following way:  “Budget meeting 02/02/2020 at 10 am (EOM).”

FWD - Forward. Most email programs use this abbreviation to indicate forwarded messages.

NRN - No Reply Necessary. If you don’t need a response, you can end your email or subject line with the NRN acronym. For instance, “Meeting changed 9 am to 11 am, NRN.”

P.S. - Postscript. Us it when you need to add extra information at the end of an email.

PRB - Please Reply By. People use it if they need the recipient to reply by a specific date and time.

SFW - Safe For Work. Used when sending something that looks or sounds bad, but it really isn’t. SFW means that the piece of information would be acceptable to view in public.

RR - Reply Requested. This one is the opposite of NRN.

  • Status acronyms

IAM - In a Meeting.
