When Apple released iOS 26 on Sept. 15, the update included a call screening feature to help block spam calls, and it can also screen text messages on your iPhone. With iOS 26, Messages can hide notifications and filter out messages from unknown senders and spam texts so they don't clog your inbox.
When these features are enabled, those messages will be filtered to their own folder in Messages without altering you. Once these messages are in their respective folders, you can look through them at your own pace to make sure you haven't missed anything important, or you can delete them without a second thought.
Here's how to enable the new text screening features on your iPhone in a few easy steps.

How to block spam and messages from unknown senders
This feature was automatically enabled for me when I updated to iOS 26, but here's how to make sure spam texts and messages from unknown senders are being filtered on your device.
1. Open Settings.
2. Tap Apps.
3. Tap Messages.
Under Unknown Senders, you'll see toggles to enable Screen Unknown Senders and Filter Spam.

Enabling Screen Unknown Senders can filter out any messages from unknown numbers. So, it could filter out a message from a family member who just got a new phone number, or a message asking for feedback on services. For example, my wife and I requested a city service, and after the service was complete, the city sent me a message asking for feedback. But since the message was from an unknown sender, it was filtered out of my inbox.
According to Apple, if you enable Filter Spam, your device's on-device detection filters will also hide spam from your inbox. My iPhone marked a few scammy-looking messages as spam sent them to their own folder. Messages in the spam folder automatically delete after 90 days.

My device also said that messages from unknown senders may also be marked as spam and sent to your spam folder. It's a good idea to check the folders from time to time just in case a non-spam message slipped through, but I never had that issue.
Where to find the spam and unknown sender folders
Once your iPhone filters out messages from unknown senders and spam, you can find them in Messages. To see these messages, go into Messages and tap the inverted pyramid icon in the top right corner of the screen. This will open a new menu that shows you different folders for each filter, including Unknown Senders, Transactions and Spam. Tap into any of these to see the filtered messages.

If a message gets filtered into Spam but it's not, you can long-press on the message and see an option to Remove from Spam. And if you want to move a message from Unknown Senders to your main mailbox, tap into the message and then tap Mark as Known near the bottom of the chat. Then your iPhone will ask you to add the sender to your Contacts.
These filters are pretty good, though. I haven't needed to move messages from Spam or Unknown Senders once, so you might not need to either.
