The Custom Report Builder and Mailing Overview report offers open environment tracking. This mean you can see tracking by email clients, reading environments, and client platforms based on where the open occurred.
Below are some of those terms and their definitions:
Email Client: represents the Email Clients or Browsers where an email is opened. "Other" means a Browser is populated, but not one we can identify. Some examples are: Windows Live Mail and Thunderbird.
Reading Environment: represents whether the email is opened on a mobile device, using a desktop application (i.e. Outlook), or using a web Browser.
- "Desktop" is an application, like Outlook or Thunderbird.
- "Web" is Browser based email clients like Yahoo.
- "Mobile" is an application on a mobile device like Apple Mail.
- "Unknown" represents no value returned from the browser or email client because it's an environment that doesn't conform to standards.
Client Platforms: represents what type of device is used to open an email.
