Hello @HSACC ,
We're able to report if an email is opened on mobile versus desktop, shown on your email's Reporting subtab of its overall reporting page after sending. Beyond that we don't report on the exact email apps or operating systems / devices (e.g. Mac vs PC, Android vs iPhone) that a contact uses. Do you have any previous examples of us providing such reporting to you?
Some third party sources may have reporting on overall devices and apps used on a yearly basis, such as this one mentioned in our blog post on common display issues.
