If you are using multiple Email Accounts, you can add them all to the Mail App on iPhone and access all your Email Accounts from within the Mail App.
Once Email Accounts are added to iPhone, you will be able to operate all your Email Accounts from within the Mail App, without the need to login to your individual email accounts.
The Mail App automatically separates Email Messages received from different Email providers and Groups them in-to separate Folders, named after the Service provider (Gmail, Outlook and others).
