Please provide us with the Browser, Device and Operating System from the Receiver of the Marketing Email on the Marketing Email Insights tab.

The Insights tab on the Marketing Email do provide us with a large amount of data. However, with the Apple Mail Protection Policy in place since last September, all Marketing Emails send to Apple Mail are pushed back to Dynamics 365 Marketing as an Open. So the Open Rate does not give us full information anymore. To clear out those Opens from an Apple device, to get a more clear Open Rate, we would need to see this information.
