Web version and Other analytics results

Your Email Analytics reports provide data on the email clients your subscribers are using. Some ISPs use technologies that can mask a subscriber's exact device depending on how they open your email. Litmus provides Web version and Other designations to capture these opens.

Web version 

These opens are most frequently made within an email client with a small market share like a regional ISP such as Comcast or Verizon. An email that is viewed within a web browser from users clicking on the hosted version or "Having trouble? View this in your browser" link, or if you include a link to your email in Facebook or Twitter updates also are included. Web version opens can also occur when you are previewing your email's template in your ESP or HTML editor prior to sending if you have included your Email Analytics code within the preview. You can check the URL of these opens within the Individual-level Data report within the referrer data field.


This category of opens includes desktop or mobile clients that we don't recognize, or other email clients that may break or distort their referrer or user agent. If you see Other opens listed for webmail clients like Outlook.com > Using Other, this means the webmail client had been viewed in a browser with a smaller market share (Flock, SeaMonkey, etc.).

As of August 2023, Yahoo and AOL opens will be classified as Other due to changes in their processes.

You can also check the user_agent and referrer data fields for these opens in your Individual-level Data Report CSV.
