Email Analytics - how it works
We know our Email Analytics data sounds too good to be true. No one has collected this kind of data before so it's understandable that you'd be intrigued about how we're doing it.
How it works
Naturally we can't explain in complete detail exactly how it works. That's our secret sauce. However, we can tell you that Email Analytics is building on the principle of image pixel tracking. That's the same technique that your email service provider uses to report your open rate. When a customer opens your email, the image pixel is loaded. This counts as an open. What we've done is take that concept five steps further.
Using a variety of image pixels along with our deep knowledge of how email clients work (and some very clever server-side manipulation of data), we're able to track a much wider range of actions that just the open. We can tell if someone read the message, what email client they used, whether they were on a mobile device, and so on.
Could the Litmus tracking code negatively impact a campaign?
We've tested our Email Analytics tracking across tens of thousands of recipients, and across every major email client. There is no way it will negatively affect your campaign.
Limitations to this form of tracking
Since we rely upon an image loading, recipients who do not enable images for your email can't be tracked. Email Analytics is a way to break down your open rate to give you further insight into the recipients who did open your message.
Engagement tracking, or how long your email was open, is limited when recipients are behind a proxy server. We are able to collect recipients' opens, but their engagement and behavior data will be limited by settings on the proxy server. This affects Gmail subscribers in particular.
Furthermore, there are a very small selection of email clients for which we can't collect this advanced engagement and behavior data. However, since we can detect which email client a recipient is using, we're able to accurately exclude these people from our reports. This way the data remains perfectly accurate, too.
