You can flag an email if it’s important, which makes it easier to return to later. While reading an email, tap the flag icon on the toolbar and then choose the Flag option.
In the Inbox list, that message will now have an orange dot next to it, signifying that it has been flagged. From here you can also flag multiple messages by tapping Edit followed by the clear dots next to each one. Now select Mark and choose Flag.
From the main Mailbox view you’ll see a Flagged folder. Use this to quickly access only emails that have previously been flagged.
