Managing Message Settings

Customizing Notifications

  1. Open Settings: Go to “Settings” and select “Notifications.”
  2. Messages Notifications: Scroll down and tap on “Messages.”
  3. Customize Alerts: Here, you can customize how you receive notifications for messages, including sounds, banners, and app icon badges.

Filtering Unknown Senders

As mentioned earlier, you can filter unknown senders by going to “Settings” > “Messages” and toggling on “Filter Unknown Senders.” This keeps messages from unknown contacts in a separate list.

Archiving Messages

At this time, iOS doesn’t offer a built-in archiving feature for messages, unlike some email platforms. However, you can create a “Saved” folder or label in your messages to manually organize important conversations. Simply create a new conversation and label it as “Saved” or something similar.

Privacy Considerations

While blocking and deleting messages can help you manage your digital interactions, it’s important to remember that the messages you send and receive can still be accessible to others in certain circumstances. For instance, messages can be saved in iCloud backups unless you choose to exclude them. Moreover, if your iPhone is part of a family sharing group, the organizer can enable a feature that allows them to see your messages.

Additionally, blocked contacts may still be able to leave voicemails, and notifications from blocked numbers might still appear in your voicemail tab. It’s a good practice to regularly review your blocked contacts and adjust your settings as needed.


Effectively managing your messages on your iPhone is essential for maintaining digital hygiene, privacy, and organization. Whether you’re blocking unwanted contacts, deleting clutter, or customizing your message settings, these actions empower you to curate your digital communication experience. By following the step-by-step instructions provided in this guide, you can take full control of your iPhone’s Messages app, ensuring that it remains a tool for efficient and positive interactions.
