Tired of Spam Texts? How to Use iPhone Messages Filters on iOS 26

We all know how messy the iPhone’s Messages app can get. Spam texts, promotions, bank OTPs, and random messages from unknown numbers often flood your inbox, making it easy to miss what’s important.

With iOS 26, Apple has added smarter Messages Filters that automatically organize your texts into categories, screen unknown senders, block spam, and even help you find messages and attachments faster with improved search.

In this guide, I’ll explain what Messages Filters are and how you can use them to clean up your iPhone inbox.

What are Messages Filters on iPhone?

Messages Filters are Apple’s built-in smart filters that automatically sort your texts (iMessage, SMS, MMS, and even RCS) instead of dumping everything into one big list.

Powered by on-device machine learning, they categorize your texts by sender, date, attachments, and keywords. That means:

• Your main inbox only shows messages from people you know.
• Spam and promotional texts are separated.
• You won’t get notifications for unknown senders or junk.
• Searching becomes faster and more accurate.
• Important conversations don’t get buried.

How to Filter Unknown Senders and Spam on iPhone

In iOS 26, Apple has upgraded Filter Unknown Senders into Screen Unknown Senders. Messages from numbers not in your contacts (or people you’ve never messaged before) are automatically moved out of your main inbox.

How to turn it on:

1. Open Messages. 
2. Tap the Filters button at the top right of the conversation list. 
3. Choose Manage Filtering. 
4. Toggle on Screen Unknown Senders and Filter Spam.
   

What happens next:

1. Messages from unknown senders, including texts from businesses, go to a different list. Tap the Filter icon at the top and select Unknown Senders. Now, you will see all conversations you’ve never interacted with before. 
2. To view the suspicious texts, select Spam from the filters list. 
3. The filter button in Messages will show a badge number signaling how many messages got diverted.  
4. By default, some time-sensitive messages (e.g., verification codes) may still appear in your main inbox for a short time before being moved.  
   

New in iOS 26: On-device spam protection. Your iPhone now detects spam without relying on your carrier or third-party apps, and it improves over time with your feedback.

How to Allow Notifications for Certain Messages

By default, iOS 26 blocks notifications from unknown senders to reduce distractions. But you can choose which categories still send alerts.

How to whitelist categories (US, Brazil, and India only):

1. Open the Settings app, scroll down, and tap Apps.
2. Select Messages and go to the Unknown Senders section.
3. Here, tap Allow Notifications and toggle on which types of filtered messages still trigger notifications:
   • Time Sensitive: Includes OTPs and urgent alerts.
   • Personal: Contacts identified not as businesses or organizations.
   • Transactions: Order updates, receipts, and payment confirmations.
   • Promotions: General offers and bulk messages from companies.

After you allow a category, those messages will send notifications and stay in your conversation list for about 8 hours, then move back to Unknown Senders.

Tip

If you only want to keep selected chat threads from a category, you can manually move them to your main inbox. In Messages, go to the Unknown Senders list, open the conversation, and tap Mark as Known. Then future messages from that sender will show normally.

How to Enable SMS and RCS Message Filters

Apple also lets you filter SMS/MMS/RCS texts into categories like Transactions and Promotions.

To enable:

1. Go to Settings > Apps > Messages. 
2. Scroll down to Unknown Senders section, tap Text Message Filter. 
3. Select Text Message Filter. 
4. If you have third-party message filter extensions, you can enable them here, too.
   

Once enabled: 

1. Messages like bank alerts, receipts, tickets, go into a Transactions tab. In Messages, tap filter icon > Transactions and select between Finance, Orders, and Reminders to view the filtered messages.
2. You will find the messages with offers and marketing content on the Promotions tab.
3. The system gradually learns as you interact with messages, and it improves categorization.
   

Note

This filter doesn’t apply to senders you’ve replied to three or more times. Therefore, if you frequently chat with someone, their texts will always show in your main inbox, regardless of what type they are.

How to Use Improved Search in Messages

One of the coolest upgrades in iOS 26 is smarter search filters within Messages, powered by Apple Intelligence.  

Here’s how it works: 

• Even if you don’t remember the exact message wording, you can search using more natural language like “family pictures from our beach vacation in June.” And you will get the photo attachments. 
• Search now understand context. So, it can provide results based on phrases that are relevant to what you typed. For example, if you search for sand, it may show texts related to the ocean or beach. 
• You can also search by message attachment categories like Photos, Wallet, or Documents.  
• Use multiple criteria, e.g., search “Links [word] from Mom” or “Photos in Promotions.”  
• Because of on-device intelligence, search results are faster, with fewer irrelevant hits. 

How to use search filters:

1. Open Messages and tap the Search bar at the bottom. 
2. Type a word to see contacts, text messages, links, and attachments that have that word. 
3. Select See All to get more search results. 
4. Tap a search result to jump to the chat. 
5. Type a contact name and select Messages with: [contact name]. 
   • Enter a word to see text messages from that contact containing those words. 
   • Type Documents to get document files shared with the contact. 
   • Select Photos to see images sent to or received from the contact. 
   • Tap Link to go through all the links in the chat. 
   • Select Location to see the map links. Further, you may type a word related to the location you are searching. So, you can get the exact map links with that word. 

If you have a newer iPhone that supports Apple Intelligence, the suggestions might auto-refine as you type.  

Troubleshooting Common Issues 

Even great features sometimes act up. Here are a few common hiccups and fixes: 

Problem	Possible Cause	Fix / Tip
An Important message from an unknown sender is hidden	You forgot to check “Unknown Senders” tab	Build a habit to check there. Mark that sender as Known to avoid future misses.
SMS filter not showing categories	Filter not enabled, or device not supported	Re-enable it from Settings > Apps > Messages > Text Message Filtering; verify region/carrier support.
Search filters not narrowing properly	Maybe the filter keywords are too broad	Use more specific terms, combine filters (sender + type).
Notifications turned off for filtered messages	You disabled them under Unknown Senders settings	Go to Settings > Apps > Messages > Allow Notifications and toggle the types you want alerts for
A sender you replied to, but is still filtered	The “replied 3× rule” might not always be recognized immediately	Mark them as Known manually, or add to Contacts

Final Thoughts

With Messages Filters in iOS 26, Apple makes it much easier to keep your inbox clutter-free. Between Screen Unknown Senders, SMS categorization, and smarter search filters, you’ll spend less time digging through junk and more time focusing on the conversations that matter.
