# Send Email When New Mailgun Messages Fail Delivery

Source: https://blog.ferstar.org/posts/notify-email-on-mailgun-delivery-failure/





SaaS 服务用着就是舒服，更换 Mailgun 后邮件投送率大大提高，不过还是有漏网之鱼，比如网易企业邮箱，会标记垃圾邮件拒收，没办法必须给上个发送失败的通知了 。

通过几个 SaaS 服务组合来完成这个需求：

1. Mailgun webhook
2. Zapier Zaps
3. IFTTT webhook
4. Telegram Group Message

最终效果是如果信件被拒收会受到一封电报消息，如图：

美中不足的是 Zapier 免费版每月仅能触发100次，不过暂时也够了，被拒收的情况很少。
