Show sender name in message email

[lehner_andreas]

Hi there,
How can I show the sender name in the subject line of a message sent on the platform?
In the template version it works, but none of the tokens seems to show the sender name.

%user_name% , %message_url% , %message_text% , %message% , %sender% , %recipient% .

Hi! You can use %sender.display_name% token.

Thanks @Fabricator .
Just out of curiousity, is there a central place where to find all the tokens?
