You can flag important email messages, create flagged mailboxes, and flag messages from VIPs. You can also block messages from specified senders.
A message you flag stays in your Inbox and is easier to find later. You can flag a Primary message, flag all Transactions, Updates, or Promotions messages from a single sender, or flag just one of them, and change or remove a flag later.
Here’s how to flag or block emails in Mail on iPad.
Flag an email
Flag an important email message so it’s easier to find later. It stays in your Inbox. It also appears in the Flagged mailbox.

Do any of the following:
- Flag a Primary message: Swipe left on the Primary message, then choose Flag.
- Flag all Transactions, Updates, or Promotions messages from a single sender: Swipe left on a message in the Transactions, Updates, or Promotions message list. Choose Flag.
- Flag a single Transactions, Updates, or Promotions message: Tap a message to open the sender’s digest view and swipe left on the message. Tap the Flag Message button.
To change or remove a flag, open the message, tap the More Actions button in the bottom-right corner of the message, tap Flag, then select another color, or tap Unflag.
A flag you add to a message shows up on it in Mail on all your Apple devices signed in to the same Apple Account.
Quick tip: Add the Flag button to the Mail toolbar, and it’s easier to access. See our article, Customize the Mail toolbar.
