Apple’s Mail app in iOS 18 introduced automatic inbox categories, but the feature becomes far more useful once you realize you can manually control where specific senders appear.
The new system sorts incoming email into four sections: Primary, Transactions, Updates, and Promotions.
The idea is similar to Gmail’s tabbed inbox, where important conversations stay in Primary, while receipts, newsletters, and marketing emails are filtered elsewhere.
In practice, the sorting isn’t always accurate, especially for emails you actually want to see right away. That’s where manual categorization comes in.
If Mail keeps placing important messages in the wrong category, you can override Apple’s sorting and assign a sender to a specific category permanently. Once set, future emails from that sender will automatically go to the category you chose.
How to manually categorize a sender in Apple Mail
- Open the Mail app on iPhone or iPad
- Find an email from the sender you want to change
- Swipe left on the message
- Tap More
- Scroll down, and tap Categorize Sender
- Choose Primary, Transactions, Updates, or Promotions
After doing this once, Mail will remember your choice and route future emails accordingly.
This small setting fixes one of the biggest frustrations with the new inbox system. Instead of constantly checking multiple categories, you can ensure important people and services always land in Primary, while newsletters and marketing emails stay out of the way.
The feature doesn’t completely replace traditional inbox management, but it gives users more control over Apple’s automatic sorting.
For anyone using the Mail categories in iOS 18, manually assigning a few key senders can make the system significantly more reliable.
