You can either enable or disable push notifications according to your preference. If you want to enable push settings only for certain applications, you can do it from the device settings. You don't have to be on a particular app to receive push notifications as they appear even if the app is not running on your device. On an iPhone, you have the Push and Fetch option for each configured email account.

Whereas in Fetch, the Mail client searches the mail server for new emails and fetches them. Proceed the steps that are given below to turn on the iPhone mail push settings.
