post type question

Hi, I add the code below to add post type ‘job’. If I add the below code, does email send out posts from both post types ‘job’ and ‘post’, or only ‘job’?

It seems if I add code below, it will send ‘job’ only, and ‘post’ will not got sent. But if I don’t add code below, then posts will got sent from default ‘post’ post type.

// add job post type to subscribe2
function jobs($types) {
$types[] = ‘job’;
return $types;
}

add_filter(‘s2_post_types’, ‘jobs’);
