Error: The XML content could not be parsed. There is a problem at line 1, column 383. Parser message

[Deepak Nagaraj]

the below error message is triggered in the email notification when someone tags me in the Confluence page.. Any workaround to be done to the page to avoid this?

Error: The XML content could not be parsed. There is a problem at line 1, column 383. Parser message: Unexpected character '<' (code 60) excepted space, or '>' or "/>" at [row,col {unknown-source}]: [1,383]
