That is not what I mean, I have deleted the tags [#first_name#] [#last_name#], because they didn’t work.

This example shows an email sent to me (Jenny Lenting) and sent by the admin.
Underneath ‘Dit bericht is van’ (This message is sent by) I added the tags [#first_name#] [#last_name#], because this would show the name of the sender. But as you can see the first and last name of the recipient is shown.
