CC Email is not receiving c#

string Body = "Test Body";
string Subject = "Subject";
string FromAddress = "Name@Domain.com"
string ToAddress = "To@Domain.com"
string CcAddress = "Cc@Domain.com"

 System.Net.Mail.SmtpClient client = new System.Net.Mail.SmtpClient();

  MailMessage msg = new MailMessage();
  msg.Subject = Subject;
  msg.Body = Body;
  msg.From = new MailAddress(FromAddress);
  msg.To.Add(ToAddress);
  msg.CC.Add(CcAddress);

 client.Send(msg);

To Email is receiving but cc Email is not receiving. Is there any missing line or code?
