Thanks, that's awesome! Will it make its way into the plugin itself in one of the new updates?

Im confused. In the plugin FAQ it says

You can add your own CSS code for desktop and mobile. Just add this example to your (child-)themes functions.php and customize it:

add_filter( 'haet_mail_css_desktop', function( $css ){ $css .= ' h1{ border-bottom: 2px solid green; } '; return $css; });

However, this does not work and there is no haet_mail_css_desktop defined in the plugin.
