Report: "Opens by email client" for ALL emails in aggregate
Under a given sent email, on the Performance tab, is "Opens by email client". This shows the email clients your receipients used for that particular email send. I would like to see this same report for ALL emails sent during a given time frame. We're trying to assess the impact of iOS15 email privacy, and need to determine how prevelant Apple Mail is for our consumers. We'd also use this for optimization priotization. Ideally would be able to select date range and filter by email type.
