What does Filter Unknown Senders mean on an iPhone? This feature lets the Messages app automatically stop texts from numbers not in your contacts from cluttering up your inbox. This is an easy way to stop spam texts from bothering you without having to block texts on iPhone (which has to be done number by number).
Let's go over how to Filter Unknown Senders, and also where Filter Unknown Senders sends potential spam texts, so you can look over these messages. Keep in mind this will not block spam texts on iPhone; it will simply allow you to ignore them more easily and get to them when you have time.
- Open the Settings app.
- Tap Apps.
- Scroll down and tap Messages.
- Toggle on Filter Unknown Senders.
- Now open the Messages app.
- You'll see that it looks a little different; you should see Filters in the upper-left corner if you're not already on the filters screen. Tap Filters.
- From this screen, you can choose All Messages to see messages from all senders, or you can choose either Known Senders, Unknown Senders, or Unread Messages to see messages in those categories.
Now you can choose to open up your Messages app to the Known Senders messages, and only review Unknown Senders when you feel like it. Be sure to check out our free Tip of the Day for more great iPhone Messages tutorials.
