iOS 11 has a new feature called “Delete Emails.” This feature allows you to delete emails from your account without having to go through the process of deleting them on your computer. To use this feature, you first need to create a new account on iOS 11. Once you have created an account, open the Settings app and select the Accounts tab. Then, click on the “Add Account” button and enter your email address into the text field. Once you have entered your email address, you will be able to see a list of all of your emails. You will also be able to see which emails are currently in use and which are not. The email that is in use will be highlighted in blue and the email that is not in use will be highlighted in green. To delete an email, just tap on it and then select “Delete.”
