In the blog article iOS 15: How to Prepare for Apple’s Changes, it states users can send to their Apple Mail users separately to measure the impact of the updates.
We haven’t yet segmented our profiles by email client, and the only information I can find on email clients is in the Email Opens by Email Client. I’m trying to segment out Apple Mail profiles, like the article suggested.
Any clue on how I can segment out profiles by email client? Thanks.
