End of message

End of message or EOM signifies the end of a message, often an e-mail. The subject of an e-mail may contain such an abbreviation to signify that all content is in the subject line so that the message itself does not need to be opened (e.g., "No classes Monday (EOM)"). This practice can save the time of the receiver and has been recommended to increase productivity.

EOM can also be used in conjunction with no reply necessary or NRN to signify that the sender doesn't require (or would prefer not to receive) a response (e.g., "Campaign has launched (EOM/NRN)") or reply requested or RR to signify that the sender wishes a response (e.g., "Got a minute? (EOM/RR)"). These are examples of Internet slang. EOM is often used this way, as a synonym to NRN, in blogs and forums online. It is often a snide way for commenters to imply that their message is so perfect that there can be no logical response to it. Or it can be used as a way of telling another specific poster to stop writing back.

In earlier communications methods, an end of message sequence of characters indicated to a receiving device or operator that the current message has ended. In teleprinter systems the sequence, NNNN, on a line by itself, is an end of message indicator. In several Morse Code conventions including Amateur Radio, the prosign AR (dit dah dit dah dit) means End of Message.

EOM is similar in concept to the EOF, or end of file. The EOF is placed at the end of a file to signify to the user where the end of file is.

Other Abbreviations

No internal message (NIM) can be used at the end of a subject line of an e-mail or online forum posting to indicate that the entirety of the message is contained in the subject line. For example, an email subject line might read, "Will be home by 6 pm; NIM".

Also commonly used is n/t, which stands for no text.
