You might be wondering why your customers' emails on your orders page are not shown to you at first sight. This process of hiding the original details of a customer is called Data masking.
Data masking has one evident reason behind it: to protect your customers' data from being seen unintentionally by third-parties.
Of course, you can still view your customers' data as you are entitled to have it in order to deliver your services.
You can view every email by simply clicking on it.
Further, of course, you can also still search for particular emails if you want to view your customers' orders as the details will then be shown to you.
