How to Show “To” & “CC” Label in the iPhone Mail App is most reliable when you identify the exact feature involved and use the current supported workflow.
Steps
- Open Settings on the iPhone.
- Go to Apps > Mail or Mail settings, depending on the iOS version.
- Look for the option labeled Show To/Cc Labels and turn it on.
- Open Mail and check messages in the inbox/list view.
- Turn the option off later if the extra recipient labels make the list too busy.
How it works
Show To/Cc Labels helps indicate whether a message was addressed directly to you or copied to you. Apple’s Settings organization has changed across iOS releases.
Important considerations
This display option does not reveal hidden Bcc recipients and does not change how messages are sent.
Additional guidance
When enabled, the label can help you quickly see whether a mailing-list message or group email was sent to you directly or as a copy. It is only a list-view cue; open the message header/details when you need the complete visible recipient information.
Practical notes
This setting is especially useful when you receive many group or distribution-list messages. A To label can help distinguish direct mail at a glance, but the absence/presence of a label is not a spam or importance indicator. Use Mail’s sender and filtering controls for those decisions.
