How to Mark an Email as Unread on iPhone

Before diving into the step-by-step process, it’s important to note that marking an email as unread will change its status so it appears as if it hasn’t been opened yet. This is a useful feature when you want to remind yourself to revisit an email later.

Step 1: Open the Mail App

Open the Mail app on your iPhone where you receive and manage your emails.

When you open the Mail app, you’ll see your inbox with a list of emails. You might have different mailboxes if you have multiple email accounts set up on your phone.

Step 2: Find the Email

Find the email you want to mark as unread. You can scroll through your inbox or use the search function to locate it.

If you have lots of emails, it might take a moment to find the exact one you’re looking for. Don’t rush – it’s there!

Step 3: Swipe Left on the Email

Swipe left on the email to reveal options such as More, Flag, and Trash.

Swiping left is a common gesture in iOS for additional options. Just make sure you don’t swipe too far or you might accidentally delete the email!

Step 4: Tap on ‘More’

Tap on the ‘More’ option that appears after you swipe left on the email.

‘More’ usually gives you additional actions you can take concerning the email that aren’t immediately visible.

Step 5: Choose ‘Mark as Unread’

After tapping on ‘More,’ a menu will appear. From this menu, choose the ‘Mark as Unread’ option.

Once you’ve selected this, the email will instantly appear as if it hasn’t been opened, and the unread counter on your Mail app’s icon may increase by one.

After completing these steps, the email will now be marked as unread. It will appear bold in your inbox, just like any other unread message. This can help you remember to come back to it later when you have more time to give it the attention it deserves.

Tips for Marking an Email as Unread on iPhone

  • Tip 1: You can also mark an email as unread by opening the email and tapping on the flagged icon, then selecting ‘Mark as Unread.’
  • Tip 2: To mark multiple emails as unread at once, use the ‘Edit’ button in the top right corner, select the emails, then choose ‘Mark’ and ‘Mark as Unread.’
  • Tip 3: Remember that marking an email as unread won’t undo any actions you’ve taken in the email, such as clicking on links or replying.
  • Tip 4: Use this feature to set aside emails that require a detailed response or follow-up action.
  • Tip 5: If you’re worried about forgetting about the unread email, set a reminder or note to make sure you come back to it.
