Apple and Google privacy practices
Apple and Google together power over 80% of email platforms in North America and they have measures in place that makes it impossible to know what device was used to open emails or if the email was opened in the first place.
Apple's Mail Privacy Protection setting is aimed to prevent senders from knowing if and when an email was opened.
Google also has privacy measures in place to prevent email senders from knowing what device is used to read emails on Google powered platforms.
