If you’re like most people, you probably have a mailbox on your iPhone. But if you want to delete a mailbox, there are a few things you need to know. First, the iPhone doesn’t have a built-in feature to delete mailboxes. You’ll need to use an app like Mailbox Deletion or Mailbox Delete Pro. Second, the deletion process will vary depending on the app you use. With Mailbox Deletion, for example, you’ll need to enter the name of the mailbox and the date it was last used. With Mailbox Delete Pro, however, you just need to press “Delete” and your mailbox will be deleted automatically. Third, be sure that your email address is associated with your mailbox before deleting it. If not, your email will be inaccessible until it’s deleted and new emails will be sent to those addresses instead.
