Why Can’t I Delete All Unread Emails on iPhone?

Some of the reasons why you might be unable to delete all unread emails on iPhone include:

1. Inability to select multiple emails

If you’re unable to select multiple emails, it could be because the ‘Edit’ button is not active.


Tap on the email you want to delete, hold it until you see a checkmark in a circle around the email. Now you can select multiple emails.

2. Mailbox size limitations

Mail services usually have mailbox size limitations. If your mailbox has exceeded its limit, you may not be able to delete emails.


Free up storage space by deleting unwanted emails, moving important emails to different folders, and ensuring that you empty your trash and spam folders regularly.

3. Mail syncing error

A syncing error could cause problems when performing an action, such as deleting emails.


Close the Mail app, restart your iPhone, and try again. If the problem persists, check your internet connection and re-authenticate your email account.

Additional Tips

  • Regularly delete unwanted emails to keep your mailbox tidy.
  • Unsubscribe from email chains and newsletters that you’re no longer interested in receiving.
  • Use filters to help organize your mailbox and delete emails based on specific criteria.
