Automatically categorize incoming email in Mail on Mac
The Mail app automatically sorts your email messages into categories to help you find and manage messages more quickly (not available in all countries or regions).
Primary: Find personal messages and time-sensitive information.
Transactions: Keep track of your confirmations, receipts, and shipping notices.
Updates: Catch up on news, newsletters, and social updates.
Promotions: Browse your coupon and sales emails.
Note: When a Transactions, Updates, or Promotions message includes time-sensitive information, it is also included in the Primary message list.
