How Do You Send A CC?

Quick Fix:

Open any email client (Gmail, Outlook, Apple Mail, etc.), start a new message, click the "CC" button next to the "To" field, and type your recipients. If you don’t see it, check your client’s settings or hit Ctrl+Shift+C (Windows) or Cmd+Shift+C (Mac).

What's Happening

CC (Carbon Copy) lets you send an email to extra people while showing everyone’s addresses to the group.

Think of it like mailing a letter to your boss and also handing a copy to your coworker—everyone knows who else got it. Unlike the "To" field (for the main recipients) or "BCC" (which hides addresses), CC keeps things transparent. It’s great for keeping people in the loop without expecting a reply, but use it wrong and you’ll flood inboxes or accidentally share private emails.

Step-by-Step Solution

Follow these exact steps for the four most common email clients.

All clients work similarly, but the menus hide in slightly different spots.

Gmail (Web/Desktop App)

Hit Compose (or press C if you love shortcuts).
In the new window, click CC—it only appears after you click the "To" field or start typing.
Type the email(s), separating addresses with commas.
Write your message and click Send.

Microsoft Outlook (Windows/Mac)

Open Outlook and click New Email (or press Ctrl+N/Cmd+N).
Look below the "To" field for the CC line. If it’s missing, click CC on the ribbon.
Type or paste the address. Outlook will suggest contacts as you go.
Hit Send when you’re done.

Apple Mail (macOS/iOS/iPadOS)

Open Apple Mail and click New Message (or press Cmd+N).
Next to the "To" field, click CC—it might look like a dropdown.
Enter the address(es). On iOS/iPadOS, tap Cc/Bcc and add them there.
Send it off.

Thunderbird (Desktop)

Click Write to start a fresh message.
If CC is hidden, go to View > Headers > All.
Add recipients in the CC field. Thunderbird keeps "To" and "CC" neatly separated.
Send the email.

If This Didn’t Work

Try these three quick fixes if the CC field vanishes.

Don’t worry—it happens to everyone.

Check the email format: Gmail, for example, hides CC until you start typing. If it’s still missing, click the label next to "To" and pick CC.
Use keyboard shortcuts: If menus act up, try Ctrl+Shift+C (Windows) or Cmd+Shift+C (Mac) to force CC to appear.
Switch to "All" view: In Outlook or Thunderbird, set headers to "All" to reveal hidden fields like CC or BCC.

Prevention Tips

Follow these best practices to CC like a pro and avoid headaches.

Done right, CCing keeps everyone on the same page. Done wrong, it creates chaos.

Use CC only when necessary: Google Support says CC should be for stakeholders who need visibility, not for quick "thanks!" replies. Microsoft Support warns that overusing CC clogs inboxes.
Double-check recipients: Always review "To" and "CC" before sending. One wrong click can expose private addresses. Gmail’s recipient suggestions catch typos automatically.
Set defaults in clients: In Outlook, create a rule under Rules > Manage Rules > New Rule > Apply rule on messages I send to auto-CC yourself. In Gmail, use Canned Responses to standardize CC lists in templates.
Avoid replying-all CCs: When you reply to a group email, don’t accidentally CC the whole list. Use Reply or Reply All carefully—match the original sender’s intent.
