How to Block Notifications from Unknown Senders on iPhone

By enabling this feature, you’re telling your iPhone to separate messages from unknown senders, which includes any notifications associated with them.

After you’ve completed the steps above, your iPhone will automatically filter out notifications from unknown senders. This means that you won’t receive any alerts, banners, or notifications from anyone who isn’t in your contacts.
