Handy to know

• The pie chart includes the top seven email clients, along with an eighth segment called "All others combined".
• If a subscriber opens an email in multiple email clients, all client opens are recorded.
• Due to the way Gmail works, it's not possible to detect which device it's running on. Android, iOS and browser Gmail results are displayed under the one "Gmail" heading.
• Not every subscriber's email client can be detected, and some email programs don't identify themselves. These clients are classified as "Undetectable".
• In some circumstances, we can detect if an email was opened on a particular device. In this case, we classify this open as the device type (e.g. iPhone). However, the majority of opens (desktop or mobile) are classified by the email client (e.g. Apple Mail or Gmail),
• If a subscriber does not download images, they won't download our tracking image and no request will be made to our servers. We won't be able to determine which email client they are using.

Apple Mail (Privacy Protected)

In 2021, Apple introduced Mail Privacy Protection which gives users more control over their data. The majority of subscribers that use Apple Mail 15 have Mail Privacy Protection enabled.

This means that it's not possible to detect which device it's running on (macOS, iPhone or iPad). Therefore, all opens for this client are categorized as —Apple Mail (Privacy Protected)?. This new category is available for emails sent after February 2022.

When we detect an open from this client, we are not able to determine whether that open was generated by Apple Mail Privacy in an automated fashion or whether it was opened by the subscriber. Therefore the number of "subscribers" in this category may be inflated.
