追踪大众电子邮件活动 [英] Track mass email campaigns
问题描述
Litmus上个月发布了一个电子邮件分析服务（可能2010年）。
请参阅这里： http ：//litmusapp.com/email-analytics
Litmus released an email analytics service last month (may 2010).
See here: http://litmusapp.com/email-analytics
他们拥有非常酷的阅读率跟踪：他们可以跟踪正常阅读，Skims和Glanced /已删除。
They boast a very cool "read rate" tracking: they can track normal reads, Skims, and Glanced/Deleted.
他们如何跟踪浏览和扫视/删除？这对我来说似乎不可能：）
How can they track skims and glanced/deleted? This to me seems impossible :)
他们还跟踪前进和打印。
打印很简单（它们包括带有bg图像的css @media打印查询）。
They also track forwards and prints. Prints are easy (they include a css @media print query with a bg image).
但转发？我认为这可能是后续打开和不同IP /重址URL之间的组合。但是，这意味着如果我打开我的邮件并从另一台电脑重新读取它，它将被视为一个前进。任何想法在这一个？
But forwards? I think this might be a combo between subsequent opens and different IPs/reffering URLs. However, this means that if I open my mail and re-read it from another computer, it counts as a forward. Any ideas on this one?
总结：
Litmus电子邮件分析表示，他们可以跟踪电子邮件阅读，浏览，扫视/删除，打印和
转发。他们如何做（撇去，浏览/删除和转发）？
To summarize: Litmus Email Analytics says they can track email reads, skims, glanced/deleted, prints and forwards. How do they do it (skims, glanced/deleted and forwards)?
跟踪代码：
这是代码。您可以为每个列表/广告系列组合创建一个唯一的代码（以便您可以跟踪广告系列..），然后在电子邮件的标签之前放置以下html / css代码。
Tracking code: This is the code. You create a unique code for each list/campaign combination (so that you can track campaigns..) then you put the following html/css code before the tag of your email message.
<style>@media print{
#_t {
background-image: url('https://a6.emltrk.com/XX0000XX?p');}
}
div.OutlookMessageHeader, table.moz-email-headers-table, blockquote #_t {
background-image:url('https://a6.emltrk.com/XX0000XX?f')
}
</style>
<div id="_t"></div>
<img src="https://a6.emltrk.com/XX0000XX" style="display:none" width="1" height="1" border="0" />
测试结果：
Test results:
使用Gmail，打印跟踪工作。雅虎以某种方式失败。
Glances / Deleted实际工作，我已经测试了。
With Gmail, print tracking works. Yahoo! somehow fails. Glances/Deleted actually works, I've tested.
推荐答案
代码的工作原理如下： p>
The code works in the following way:
<style>
/* Print stylesheet */
@media print{
#_t {
background-image: url('https://a6.emltrk.com/XX0000XX?p');
}
}
/* Forward stylesheet */
div.OutlookMessageHeader, table.moz-email-headers-table, blockquote #_t {
background-image:url('https://a6.emltrk.com/XX0000XX?f')
}
</style>
<!-- Extra DIV -->
<div id="_t"></div>
<!-- Main Image -->
<img src="https://a6.emltrk.com/XX0000XX" style="display:none" width="1" height="1" border="0" />
当查看电子邮件时，有一个图像被加载。这将计算打开统计信息。
There is an image that gets loaded when the email is viewed. This counts the "opens" statistic.
还有一个额外的div（带有_t），从样式表引用。电子邮件正在打印时， @media print 部分应用背景图片。图像的网址有额外的 p 属性，这可能告诉Litmus电子邮件正在打印。
There is also an extra div (with the id _t) which is referenced from a stylesheet. The @media print section applies a background image when the email is being printed. The url of the image has the additional p attribute, which probably tells Litmus that the email is being printed.
前向统计量以类似的方式计算：当某些元素存在时加载背景图像。 Outlook匹配 div.OutlookMessageHeader ，其他（看起来像Thunderbird或许，给定 moz ）匹配 table.moz-email-headers-table ，其他所有内容都匹配 blockquote #_t （再次使用附加的DIV）。当转发的电子邮件正在组成时，这些元素由电子邮件客户端创建。这个时候，这张照片载入了 f 标志，告诉Litmus计算前进统计。
The forward statistic is calculated in a similar manner: a background image is loaded when certain elements are present. Outlook matches the div.OutlookMessageHeader, something else (looks like Thunderbird perhaps, given the moz) matches table.moz-email-headers-table, and everything else matches blockquote #_t (using the additional DIV again). These elements are created by the email client when the forwarded email is being composed. The image is this time loaded with the f flag, which tells Litmus to calculate the forward statistic.
这些统计信息然而，绝大多数电子邮件客户端将会阻止任何形式的图像，直到用户决定显示为止。大多数网络邮件客户端将完全删除任何样式表，这使得打印和转发统计信息与Gmail，Hotmail和Yahoo!等客户端无关。邮件。
These statistics must be taken with a grain of salt, however: most email clients will block images of any kind until the user decides to show them. Most webmail clients will completely strip out any stylesheets, which makes the print and forward statistics irrelevant for clients like Gmail, Hotmail, and Yahoo! Mail.
我希望这是有道理的！我还没有弄清楚扫视/删除的统计数据。当我做，我一定会让你知道。
I hope this makes sense! I haven't quite figured out the glanced/deleted statistic yet. When I do, I'll be sure to let you know.
