Unread email messages in the Mail app on your iPhone are usually identified by a small blue dot to the left of the message.
If you open the message and read it, then return to the inbox, that blue dot should be gone. But not every email needs to be read, and if you are trying to clear all of the unread messages from your inbox, then the prospect of doing that for each individual email can be fairly daunting.
Fortunately, the Mail app in iOS 9 on your iPhone includes a quick way for you to mark every email as read on your device.
Our guide below will walk you through those steps so that you can remove that red circle with the number on it and start with an inbox of messages that are all marked as read.

How to Mark All of Your Emails as Read in iOS 9 (Guide with Pictures)
The steps in this article were performed on an iPhone 6 in iOS 9. However, these steps are still very similar in newer versions of iOS, such as iOS 15, and newer iPhone models like the iPhone 13.
Step 1: Tap the Mail icon.
Step 2: Tap the Edit button at the upper-right corner of the screen.
Note that you will need to be in your inbox already for this to work. If it says Mailboxes at the top-left of the screen, then you will need to select the All Inboxes option, or the specific inbox of the account containing the messages that you wish to mark as read.
Step 3: Tap the blue Mark All button at the bottom-left of the mailbox.
In newer versions of iOS you will need to choose the Select All option at the top-left of the screen instead.
Step 4: Tap the Mark as Read option to complete the process.
In newer versions of iOS you will need to tap Mark at the bottom-left first, then choose the Mark as Read option. Note that it may take a minute or two to mark all of the messages as read if you had a lot of them in your inbox.
Now that you know how to mark all emails as read on your iPhone, you can do this periodically if you don’t like seeing a large number of unread emails in your inbox.
Can I Mark All Unread Messages as Read in the iPhone Mail App?
Yes, it is possible to perform this action using the steps outlined above. Essentially what you are doing is opening the mail folder containing the emails that you want to mark as read or unread, selecting all of them, then using the Mark tool at the bottom left of the screen. The steps look like this:
Mail > Edit > Select All > Mark > Mark as Read
If all of the emails in the current folder are already read then you will see a Mark as Unread option instead.
