EOM Meaning in Email
In email and messaging, EOM means “end of message.” Institutional email guidance documents its use at the end of a subject line when the subject itself contains the complete message. This is a convention, not a requirement.
In an email context, EOM means “end of message”; when placed in the subject line, it can signal that the subject contains the whole message.

Email Usage
MIT’s Communication Lab shows [EOM] at the end of a subject line when there is no additional message body.
Meaning
Oxford documents EOM as “end of message.”
Practical Application
Use EOM in a subject line only when the subject truly contains the entire message and the recipients are likely to recognize the abbreviation. Avoid it when details, tone, or context need a body.
Reader Check
Can the complete action/context fit safely in the subject, and will the audience understand EOM?
Worked Example
Subject: “Office closed Monday for holiday — EOM” can work for a familiar internal convention; a policy change with conditions should use a normal message body.
