大家都知道很多网站带有「邮件订阅网站」的功能，不过大部分访客即使想订阅也会因繁琐的步骤望而却步，不过今天畅想资源就来教大家如何于WordPress内向部分（随机抽取）留言者发送新文章邮件通知，让网站的精品文章能够被访客及时获取！

注意：使用该功能有可能（未经证实！）会由于类似群发而被服务商标识为垃圾邮件，一切后果自负！

提示：如果你需要添加嵌套评论回复邮件通知提示功能，请见「【纯代码】为WordPress添加评论回复邮件提醒通知功能」！

1、首先将下方代码添加到「布景函式库(functions.php)」的最底部 ?> 之前，然后点击更新档案

提示：你可以将下方代码各高亮部分修改为你想要的配置！

注意：如果您的伺服器并不支持 mail 函数，请参考「这篇文章」并使用外部SMTP发送邮件即可！
