iPhone 7 blue envelope app

In the App Store, just type “mail” (or something else, depending on your phone’s default language). The official mail app should be there, ready to be downloaded.

You shouldn't be able to delete the Mail app.

See if you accidentally moved it to a folder.

Nearly all native apps are delete-able now, but can be recovered from the App Store.
