I just fixed it myself, here is the trick.

Open custom-field-template.php and update line 3285 for:

$replace_val .= $before_value . $value . $after_value . "\n";

Here is the complete (and fixed) code:

if ( $val['singleList'] == true ) :
	if ( $before_list ) : $replace_val = $before_list . "\n"; endif;
	$replace_val .= $before_value . $value . $after_value . "\n";
	if ( $after_list ) : $replace_val .= $after_list . "\n"; endif;
endif;

I will try to contact the author of the actual plugin.

husar: You actually have to use the add_filter() function, not the add_action(). As ‘publish_post’ is a hook and not an action ??

This code should work perfectly (using the function above).

add_filter ( 'publish_post', 'email_me' );

Happy hooking!
