The newline characters started showing up in the emails when I added this line of code:

// Add in the URL information
$current_title = t('New headlines in @title', array('@title' => $feed_info->title));
$node_body .= "\n". $mini_separator . "\n" . $labour_title ."\n". url('aggregator/sources/'.$item->fid, NULL, NULL, TRUE)."\n";
