问题原因是谷歌gmail的机器人在客户打开之前就对邮件进行了打开，邮件详细信息里查看到的ip地址都是谷歌的，所以在后台进行排除。
backend>settings>campaigns>exclude-ips-from-tracking
排除的ip地址参考印度小哥给总结的ip地址：https://github.com/pksh71/gmail-bot-email-open-click-ip-ranges
另外，还有一些IP地址是谷歌的图像代理，是正常的邮件加载优化行为，可以不算做影响打开率，这些ip的agent特点：
Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko Firefox/11.0 (via ggpht.com GoogleImageProxy)
关于谷歌图像代理，可以参考文章：

Recently Gmail announced its latest feature, called Image Proxy. Before diving into details on this feature and its effect on email open detections, let me mention that it’s the only feature released by email services in the last few years that’s beneficial to email marketers.
