How to flag or block emails in Mail on iPhone

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 iPhone.

Flag an email

Flagging an important email message makes it easier to find later.

Messages you flag stay in your Inbox and also appear 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, then choose Flag.

   Flag a single Transactions, Updates, or Promotions message: Tap a message to open the sender’s digest view, swipe left on the message, then tap the Flag Message button.

2. To change or remove a flag, open the message, tap the Reply Actions button, tap Flag, and then select another color, or tap Unflag.

   Note: Flags you add to a message appear on that message in Mail on all your Apple devices where you’re signed in to the same Apple Account.
