我给你一个想法，我已经用过这样的东西了。我想知道我的插件使用的站点，我创建了一个cron作业，允许我每周向我发送一封电子邮件：

add_action(\'init\', function() {
 $time = wp_next_scheduled(\'dro_cron_hook\');
 wp_unschedule_event($time, \'dro_cron_hook\');

 if (!wp_next_scheduled(\'dro_cron_hook\')) {
    wp_schedule_event(time(), \'everyweek\', \'dro_cron_hook\');
 }
});

add_filter(\'cron_schedules\', function($schedules) {
$schedules[\'everyweek\'] = array(
    \'interval\' => 604800
 );
 return $schedules;
});

add_action(\'dro_cron_hook\', function() {

 // Here you can send the email using wp_mail() and some additional data
});
