well I did it, probably not clean, but it’s working ??

$parents = get_post_meta( $app->ID, 'job', false );
	if( ! empty( $parents ) ) {
		$msg .= PHP_EOL;
		foreach( $parents as $parent ) {
			$data = get_post( $parent );
			$appmeta2 = get_post_custom( $data->ID );

			$appdata2 = array();
			foreach( $appmeta2 as $key => $value ) {
				if( is_array( $value ) )
					$appdata2[$key] = $value[0];
				else
					$appdata2[$key] = $value;
			}
			$msg .= '<tr><td style="background-color:#E8E8E8;">' . __( 'Job', 'jobman' ) . ':</td><td>' . $data->ID . ' - ' . $data->post_title . '</td></tr>' . PHP_EOL;
			$msg .= '<tr><td style="background-color:#E8E8E8;">Department:</td><td>' . $appdata2[data4] . '</td></tr>' . PHP_EOL;
			$msg .= '<tr><td style="background-color:#E8E8E8;">Job Page Link</td><td>' . get_page_link( $data->ID ) .  '</td></tr>' . PHP_EOL;
		}
		$msg .= PHP_EOL;
	}

Goal is to get values of Custom Job Field Information;
shortcode:
[job_field4_label], [job_field4]

which looks to be the value in the wp_postmeta table metakey ‘data4’

I’ve been able to get this in frontend-application.php (custom email msg)

$msg .= '<tr><td style="background-color:#E8E8E8;">Department:</td><td>' . $appdata[data4] . '</td></tr>' . PHP_EOL;

however, this is displaying the custom data field 4 in wp_postmeta for the application rather than the post for the job description

line 831

$appmeta = get_post_custom( $appid );

	$appdata = array();
	foreach( $appmeta as $key => $value ) {
		if( is_array( $value ) )
			$appdata[$key] = $value[0];
		else
			$appdata[$key] = $value;
	}

Andy, very helpful, thank you
