推荐答案

你不能这样做。



有一些机制可以对电子邮件进行读回复，但是并非所有系统都实现它，并且大多数会在发送回复之前提示你已经请求使用它。



虽然它会很方便，但也没办法检测无法投递的邮件 - 如果域名中不存在电子邮件地址，某些系统会拒绝它们，但是很多人不会。



有可能通过为邮件中的图像设置ASPX处理程序并计算访问图像的时间来粗略计算已打开的电子邮件，但这也不一定非常准确，因为许多系统默认情况下不会在电子邮件中显示图像。 />


说实话，虽然它对于合法用途是有用的，但我很高兴这在现实世界中不起作用 - 我们会有很多，更多的垃圾邮件和垃圾邮件，如果它会立即知道哪个是活的，哪个是死的地址。

You can''t do it.

There are mechanisms which ass a read-reply to an email, but not all systems implement it, and most will prompt the use that you have requested one before sending the reply anyway.

While it would be handy, there is also no way to detect an undeliverable mail - some systems will reject them if the email address does not exist on the domain, but again many won''t.

It may be possible to get a rough count of opened emails by setting an ASPX handler for an image within the mail, and counting when the image is accessed, but that is also not necessarily very accurate as many systems do not show images in emails by default.

To be honest, while it would be useful for legitimate purposes, I''m quite glad this doesn''t work in the real world - we would have a lot, lot more spam and such junk emails if it did as they would immediately know which is a live and which a dead address.
