When you add your Google account on your iPhone or iPad in the Settings app, you add your Gmail account to the Mail app. If you prefer to use third-party email clients, you can delete email accounts from the Mail app on your iPhone or iPad.
Using the Settings app, you can sign out of any email account (including Gmail, Outlook, and iCloud), while still using the account for note synchronization, contacts, etc.
To do this, open the “Settings” application on your iPhone or iPad and go to the “Passwords and accounts” section.
Here you will see all the accounts to which you are connected. Tap an account to see its fine details.
Then tap the toggle next to the “Mail” option to turn off email synchronization. You will notice that the particular mail inbox will disappear from the Mail application.
You can return to the “Passwords and Accounts” section and follow the same process to delete email accounts from other services.
The process of disconnecting email accounts from the Mail app works for all third-party accounts. If you want to delete the iCloud email account, the steps are slightly different.
Open the “Settings” application and tap on your Apple profile located at the top of the menu.
Here, tap on the “iCloud” option.
Now scroll down and hit the toggle next to the “Mail” option.
Your iCloud email is now disabled and will no longer appear in the Apple Mail app.
To confirm, you can open the Mail application again. Instead of seeing your regular inbox, you’ll see a welcome screen asking you to sign in to an account.
