Show emails from VIP senders in Mail on Mac
You can easily keep track of email messages from people important to you by making them VIPs. Any messages in the Inbox from a VIP (even sent as part of a conversation) are displayed in a VIP mailbox (a type of Smart Mailbox). You can have up to 100 VIPs.
Make someone a VIP
In the Mail app on your Mac, select a message from someone you want to make a VIP.
Move the pointer next to their name in the message header, then click the star that appears.
You can also click the arrow in a Smart Address, then choose Add to VIPs.
If a VIP has more than one email address in the Contacts app, messages from all of their addresses are included in the VIP’s mailbox.
Show a VIP’s emails
Choose a VIP.
Only messages from the VIP are shown. If you don’t see expected messages, click Sort by at the top of the message list, then choose All Mailboxes (a checkmark shows it’s on).
To see messages from everyone again, click Inbox in the Favorites bar or the sidebar.
Remove someone’s VIP status
If you use iCloud Contacts, your VIPs are available on your other Mac computers (with OS X 10.8 or later) and iOS devices (with iOS 6 or later) that have iCloud Contacts turned on.
