You can only use this AMPscript function in MobileConnect. You can’t use this function in email messages, landing pages, or other content types.

The Msg() function accepts one parameter. The only accepted value for the parameter is 0.

This function returns the complete content of a message that was sent to you by a subscriber (an MO message).

If an MO message contains the text “OFFER John Smith”, the example code returns the entire body of the message.
