I have this little bit of code that sends me an email whenever a new posts is published by an author, but I want to be alerted to posts in 'pending' status by contributors too.

add_action('publish_post', 'send_admin_email');
function send_admin_email($post_id){
    $to = '[email protected]';
    $subject = 'New Post on The Articist';
    $message = "new post published at: ".get_permalink($post_id);
    wp_mail($to, $subject, $message );
}   

Can I have emails sent to me so I'm informed when posts are pending?

Code from userabuser's first solution, this doesn't seem to actually send emails(yes, I have changed it to my actual email address in the functions.php).

add_action( 'transition_post_status', 'pending_post_status', 10, 3 );

function pending_post_status( $new_status, $old_status, $post ) {

    if ( $new_status === "pending" ) {
        function send_pending_email($post_id){
            $to = '[email protected]';
            $subject = 'New Pending Post';
            $message = "new post Pending";

            wp_mail($to, $subject, $message );
           }
        
    }

}
