A surprise text from an unknown number can look like a delivery notice, bank alert or job offer. Apple’s Messages app lets you screen senders who are not in your contacts, so those messages stop landing in your main conversation list. Turn that setting on, then review filtered messages only when you choose.
The risk is real. An FTC Consumer Sentinel bulletin said consumers reported losing $470 million in 2024 to scams that started with text messages, with fake package-delivery problems and phony job opportunities prominent. Filtering will not stop every scam, but it adds a pause before you engage.
Can iMessage filter messages from unknown senders?
Yes. Apple’s current iPhone guidance says Screen Unknown Senders sends messages from people you have not interacted with or saved in Contacts into a separate Unknown Senders filter. Settings names vary by software version; older versions call this Filter Unknown Senders.
Filtering reduces clutter and unwanted alerts. It does not verify that a message is safe, and it does not make links or attachments trustworthy.
Does screening unknown senders block a message?
No. Screening moves the message into a separate area instead of deleting the sender or blocking future contact. You can review it later, mark a legitimate sender as known or delete and report spam. Treat everything in that folder as unverified until you confirm it independently.
How do you turn on Screen Unknown Senders on iPhone?
- Open Messages. Tap the Filters button.
- Tap Manage Filtering. Scroll to Unknown Senders.
- Turn on Screen Unknown Senders. You can also use Settings, Apps, Messages and scroll to the same setting.
- Review notification choices. Under Allow Notifications, choose which categories, such as time-sensitive codes, may still alert you. Options vary by country and region.
- Check the Unknown Senders filter. Open it periodically for messages you expected.
How do you filter unknown senders in Messages on Mac?
Open Messages on your Mac, click the filtering control at the top of the sidebar and choose Manage Filtering. Then select Screen unknown senders. Apple’s Mac Messages guide explains that filtered messages go to another folder, and notifications are optional. If you want exceptions, open Notifications and choose only the categories you need.
To review messages, open the sidebar’s Unknown Senders area. Select Mark as Known only after you recognize the sender, or create a contact.
What should you do with a suspicious text?
- Do not click or reply. Replying can confirm that your number is active.
- Do not call numbers in the message. Look up the organization’s official number yourself.
- Verify through the official app or website. Type the address or use a saved bookmark instead of tapping the link.
- Report and delete. Use Messages’ report-spam option or block the sender when appropriate.
- Protect your accounts. If you shared passwords or card details, change passwords through the real service and contact your bank immediately.
How does limiting unknown senders help you stay safer online?
Scammers rely on urgency and surprise. Screening unknown senders removes many unexpected messages from your main inbox, giving you a moment to evaluate instead of reacting to an alert. Fewer interruptions also reduce the chance of tapping a fraudulent link while distracted.
Combine the setting with strong passwords, multifactor authentication and software updates. Keep important contacts saved so legitimate messages stay visible. Turn the setting on today, then check Unknown Senders once or twice a week.
