In this post, I will show you how to mute unknown senders in Messages.
This tip is useful if you don't want to receive a notification when someone not in your contacts list (most probably a spammer) sends you an iMessage.
It's important to understand that only iMessages are concerned; SMS messages cannot be muted, unless the sender has been explicitly blocked (as explained in my previous post).
Please note that to take advantage of this feature, your iPhone needs to run at least iOS 8.
To activate this option:
Scroll down and tap on "Messages"
Scroll down and activate the option "Filter Unknown Senders"
Once activated, when you open the Messages app, you'll see two sections at the top of the screen.
iMessages from unknown senders will automatically be put in the section with the same name.
Provided that you have activated badges for the Messages app, you may see a small (1) next to the Messages app icon and not see anything in "Contacts & SMS".
It's normal, just tap on "Unknown Senders" to reveal the message that you've received.
Are you also filtering unknown iMessage senders on your iPhone?
