WP Better Emails Plugin - own tag

Question

I try to create my own tag in the plugin WP Better Email. I would like to have a dynamic title (%title%)

https://wordpress.org/plugins/wp-better-emails

I use the wp_mail function.

$header = "test";

wp_mail( $mail, $subject, $message, $header, $attachments );

Now, the %title% should take the value of $header. In this case "test".

How can I realize that? I tried something with filters, but It did not work. :-(
