So apparently EssentialsX chat doesn't support placeholders from PAPI, is there anything i can do so that the MM placeholders show up correctly in chat?

Essentials chat should be compatible with the Prefix/Suffix config options, they will not give you as much freedom as PAPI, but still be better than nothing.

Thank you for the help, is it possible for the {StatusHeart} to be put on the suffix aswell because it only works on prefix. Also having the IsMarried as an option would be amazing.

This build should make the {StatusHeart} and the {MagicHeart} placeholders also work as a suffix.
How would you use the IsMarried placeholder in your chat message?

That is great news thank you so much! I made a mistake, i meant to ask about the Heart placeholder. I would really like for the heart to appear only when someone is married. That is the best placeholder :)

Everything in the prefix/suffix will only get added to the chat if the player is married. If the prefix/suffix contains a {StatusHeart} a gray ❤️ will be added for not married players.
If there should only be an heart if they are married you can set the prefix/suffix String option to only an <heart> which will be replaced with an ❤️ .
