Hey Sarah, 

How do I delete ALL 17,000 of my UNREAD emails at once?


Inbox 17,000

Dear Inbox,

Apple doesn't offer a Select All option for unread emails in the Mail app, although this option is available for all emails in a particular inbox. Mail users must individually select unread emails and then tap Trash in order to delete all their emails at once on their iPhone or iPad. Most iOS users find this to be a tedious waste of time. Fortunately, there is a hidden workaround to delete all emails, or just all unread emails quickly. Apple may eventually eliminate this workaround for mass deleting emails on the iPhone with the next iOS update; but for now, it works as a way to get rid of all your emails at once, whether they're in your Yahoo, Gmail, or other email account associated with your Mail app.

How to Delete All Unread Emails Quickly on Your iPhone & iPad

  1. In All Inboxes, if you only want to delete all unread emails on your iPhone or another subset of emails, such as flagged emails, tap the filter icon in the lower left of your screen. Unread is the default Mail filter, but it’s easy to change
  2. When you are sure only emails you want to delete are in the inbox, then tap Edit in the upper right corner.

  3. Select an email (doesn’t matter which) by tapping and holding the empty circle to the left of it, then begin swiping up the page with your thumb.
  4. You'll see all the circles become highlighted in blue as your finger passes over them, and the number of emails you've selected at the top of the page.

  5. Once you've selected all the emails you'd like to delete, tap Trash.
  6. As you can see, before I started this process, I had over four thousand unread emails in my Inbox.

If you realize at this point that you’ve messed up and don’t want to delete everything, after all, don’t panic. Undo the mass deletion by using Shake to Undo. Just give your iPhone a shake and then tap Undo. It may take a while to restore the emails.
