    The hook also fires when clicking on the “Add New” option for the custom post type, as it creates the draft in the DB, and when calling the wp_update_post function as well.

    It’s kind of sad that this more explicit action fires before the less explicit ‘save_post’ action.

    This means if a 3rd party plugin does something using ‘save_post’ you need to use ‘save_post’ to override it too.

    // someone else's code...
add_action( 'save_post', 'wpdocs_do_something_custom', 15 );

// try to override with CPT action - DOES NOT WORK
add_action( 'save_post_third_party_cpt', 'wpdocs_override_something_custom', 20, 2 );

// you must do this to override
add_action( 'save_post', 'wpdocs_override_something_custom', 20, 2 );
function override_something_custom( $post_id, $post ) {
	// bail out if this is an autosave
	if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE ) {
		return;
	}

	// bail out if this is not an event item
	if ( 'third_party_cpt' !== $post->post_type ) {
		return;
	}

	// ... do override stuff
}

    Notify your newsletter subscribers when a new book (custom post) is added-

    add_action( 'save_post_book', 'wpdocs_notify_subscribers', 10, 3 );

function wpdocs_notify_subscribers( $post_id, $post, $update ) {

	// If an old book is being updated, exit
	if ( $update ) {
		return;
	}

	$subscribers = array( 'john@doe.com', 'jane@doe.com', 'someone@else.com' ); // list of your subscribers
	$subject     = 'A new book has beed added!';
	$message     = sprintf( 'We\'ve added a new book, %s. Click <a href="%s">here</a> to see the book', get_the_title( $post ), get_permalink( $post ) );

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