The Mail App Is Getting Better
Apple is working on improving the Mail app, starting with iOS 18.2.
This new software update will add new categories to Apple Mail. With this feature, you’ll be able to choose to have your mail automatically organized into four categories: Primary, for the most important mail; Transactions, for all the messages related to purchases or subscription services; Updates, for subscription mail and newsletters; and Promotions, for everything related to deals or sales that you may receive.
This will work automatically. To access specific messages, tap one of the categories at the top of the Mail app. You can also turn it off and return to the standard inbox by tapping the three-dot menu and selecting List View.
