iOS 17: How to Mark an Email as Unread on iPhone

Have you ever found yourself swiping through your email inbox on your iPhone, reading an important email, but then getting distracted and forgetting to respond? If you’re using iOS 17, marking that email as unread can serve as a handy reminder to circle back to it later. It’s a simple process, and I’m here to walk you through it.

Step by Step Tutorial: How to Mark an Email as Unread on iPhone

Before we jump into the steps, let’s talk about why you might want to mark an email as unread. Maybe you want to make sure it stands out in your inbox, or you need to come back to it later when you have more time. Whatever the reason, it’s a useful trick to keep up your sleeve.

Step 1: Open the Mail app

First thing’s first, open up the Mail app on your iPhone.

When you open the Mail app, you’ll see your inbox with a list of emails. At this point, you might see some emails that are already marked as unread with a blue dot next to them.

Step 2: Find the email you want to mark as unread

Next, scroll through your inbox and find the email you want to mark as unread.

Don’t worry if you have a lot of emails to sift through. You can always use the search function at the top of the Mail app to quickly find what you’re looking for.

Step 3: Swipe left on the email

Once you’ve located the email, just swipe left on it.

You’ll see some options pop up when you swipe left on an email, like “More,” “Flag,” and “Trash.” But we’re focusing on marking as unread here.

Step 4: Tap “More”

After swiping left, tap on the “More” option.

“More” will open up additional actions you can take with the email. We’re getting closer to marking that email as unread!

Step 5: Tap “Mark as Unread”

Finally, tap the “Mark as Unread” option.

And voila! The email will now appear as unread in your inbox, complete with the blue dot indicator.

After you complete the action of marking an email as unread, the email will reappear in your inbox with a blue dot next to it, signaling that it’s unread. This way, you won’t forget to come back to it later when you have the time to give it your full attention.
