How to Customize Email Settings on iPhone: Mastering Apple Mail with Smart Categories

Apple’s built-in Mail app has steadily evolved over the years, and with iOS 18.2, it introduces one of the most significant upgrades yet—automatic email categorization powered by Apple Intelligence. Whether you're aiming for inbox zero or just looking to bring a little more sanity to your daily email scroll, learning how to customize Mail on your iPhone is essential.

This article will guide you through everything you need to know—from enabling and customizing smart categories to fine-tuning swipe gestures, signatures, and more.

What Are Mail Categories on iPhone?

Starting with iOS 18.2, Apple Mail can now automatically sort your incoming emails into four smart categories:

• Primary – Personal emails and priority messages.
• Transactions – Order confirmations, receipts, billing statements.
• Updates – Newsletters, service changes, social media updates.
• Promotions – Marketing campaigns, coupons, and advertisements.

This feature helps streamline your inbox so you can focus on what's most important without being buried by promotions or non-urgent messages.

How to View and Navigate Email Categories

Once your iPhone is updated to iOS 18.2:

1. Open the Mail app.
2. You'll see category tabs at the top of your inbox: Primary, Transactions, Updates, and Promotions.
3. Tap on any category to view only those types of emails.

Apple automatically decides how emails are grouped using on-device intelligence, but you're not stuck with its choices.

How to Change a Sender’s Email Category

If you find that a specific sender is being miscategorized (for example, a personal contact showing up in Promotions), you can manually change their classification:

1. Open an email from the sender.
2. Tap the Reply icon.
3. Select Categorize Sender.
4. Choose the correct category—Primary, Transactions, Updates, or Promotions.

Future emails from this sender will now land in the category you selected. This not only improves organization but also helps the Mail app better learn your preferences over time.

How to Turn Off Mail Categories (Use List View Instead)

Prefer the classic chronological inbox without segmented tabs? You can switch back to the traditional layout with a few taps:

1. Open the Mail app.
2. Tap the “...” (three dots) in the upper-right corner.
3. Select List View.

Now all your emails will appear in a single, unified inbox, just like in previous iOS versions. Perfect for users who want a minimalist view or just don’t like the automatic sorting.

Customizing Additional Mail Settings on iPhone

Beyond smart categories, iPhone Mail offers a suite of options that can help you fine-tune your email experience.

Add or Manage Email Accounts

To manage multiple accounts from different providers (like Gmail, Outlook, or Yahoo):

1. Go to Settings > Mail > Accounts.
2. Tap Add Account.
3. Choose your email provider and follow the steps to log in.

Customize Swipe Actions

Swipe gestures can be a huge time-saver. To configure them:

1. Go to Settings > Mail > Swipe Options.
2. Choose actions for Swipe Left and Swipe Right (e.g., Trash, Flag, Mark as Read).

Adjust Email Preview Lines

Want to see more (or less) of each email in your inbox? You can change the number of preview lines:

1. Head to Settings > Mail > Preview.
2. Choose between None to 5 Lines to control how much of the message body appears beneath the subject.

Set a Default Email Account

If you use multiple email accounts, set a primary one for sending messages:

1. Navigate to Settings > Mail > Default Account.
2. Select the account you use most often.

Customize Notifications Per Account

Manage alerts and notifications to avoid overload:

1. Go to Settings > Notifications > Mail.
2. Tap on each email account to customize alert styles, sounds, and badge settings.

Create a Custom Email Signature

Give your emails a polished, professional finish:

1. Go to Settings > Mail > Signature.
2. Choose to create a universal signature or separate ones for each account.

Final Thoughts

Apple’s smart categories are a welcome addition for anyone overwhelmed by an unmanageable inbox. Whether you embrace the automated organization or prefer to customize every aspect of your Mail app manually, iPhone gives you the tools to personalize your email experience like never before.

And remember—if categories aren’t your style, switching back to List View is just a tap away.
