**Your software**  
My Mautic version is: v4.4.1  
My PHP version is: 8.0.25  
My Database type and version is: 10.6.11-MariaDB-0ubuntu0.22.04.1

**Your problem**  
My problem is:  
is it possible to set variable custom email headers for the email templates ?  
I would like to set the ID as a custom header for the email for bounce handling for each created email template

While I have no answer, I would like to see if there is one, as this could solve a problem I encountered.

Thanks for asking the question.

Kudos and best regards,

when creating a new e-mail, you can add custom headers in the advanced tab.

but I don’t think you can create custom headers in the theme.
