What does "web version" and "other" mean within my results?
You may notice that sometimes there are Web version and Other results tracked within your Email Analytics reports.
Web version opens are most frequently opens made within an email client with a small market share (for example, a regional ISP such as Comcast or Verizon), an email that is viewed within a web browser (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/Twitter updates. Web version opens can also occur when you are previewing your email's template in your ESP or HTML editor prior to sending, and you have included your Email Analytics code within this preview. You can check the URL of these opens within the individual level CSV report within the referrer data field.
Other category opens are 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 (for example, Outlook.com > Using Other) this means that the webmail client had been viewed in a browser with a smaller market share (Flock, SeaMonkey, etc. for example). You can also check the user_agent and referrer data fields for these opens in your individual level report CSV.
Note: Gmail now caches images for emails (as of November 2013) which affects how Email Analytics records Gmail opens. There is now a “Using a Browser” metric in Email Clients reports, showing initial opens from Google’s caching service (these will appear as Gmail - Using a Browser in your reports). Because of Gmail's image caching, we can no longer detect the browser associated with a Gmail open. For more information on this, check out our recent blog post.
