What is the purpose of using the 'Cc' field in an email?

The purpose of using the 'Cc' field in an email is to send a copy to multiple recipients visibly. When an email is sent using the 'Cc' field, all recipients listed in this field can see the email addresses of each other. This is useful for keeping everyone in the loop with the same information, ensuring transparency among recipients. It allows everyone to understand who has received the email and may encourage dialogue or collaboration among those included.

In contrast, other functions, such as including someone discreetly, sending reminders, or defining subject lines, do not align with the primary role of the 'Cc' field. The 'Bcc' field, for example, serves the function of discreetly including someone without revealing their email address to other recipients.
