How to Add CC and BCC Recipients in Email
You can add CC and BCC recipients to your email in two ways:
Add CC and BCC recipients using the API
Add the CC and BCC details under channel.email.append in the Notification Event API, as shown below. You can add any number of emails to CC and BCC.
Add CC and BCC recipients in the email editor
Expand ‘From’ and ‘Cc/Bcc’ details entered here will override integration configuration above the Subject field.
Enter the CC recipients in Cc and the BCC recipients in Bcc. You can also use placeholders to add CC and BCC details dynamically.

The same section also has the From Name, From Email, Reply To and Feedback ID fields. See How to override email sender details.
CC and BCC details provided in the email template override the CC and BCC details provided in the Notification Event API.
CC and BCC details in logs
In the Sent Logs, you find the recipient details (destination, CC and BCC) in the Summary tab. For the above example, the Sent Logs show the following information.
