If you have an iPad iOS 12, there are a few ways to delete an email account from your device. The first way is to open the Settings app and select the Accounts option. Then, select the email account you want to delete and click on the Delete button. The second way is to open the Mail app and tap on the three lines in the top left corner of the screen that say “Email Accounts.” Then, select the email account you want to delete and tap on Delete.
