I have a question about the email sends statistics report and more specifically the tab named emal clients. you can see the difference between the desktop and mobile.
The total opens of my email were 89 and the unique opens were 59, but it says that there were 70 unique opens on desktop and 8 on mobile. I don't really know how they calculated these numbers.
I know that it only counts the first open but where is the difference between the 78 unique opens in the email client tab and the 89 total opens or 59 unique opens in the overview tab?
