did not receive email delivery webhook of cc and bcc recipients

sending email via SES v2 SendBulkEmail

{ Destination=new Amazon.SimpleEmailV2.Model.Destination { ToAddresses=new List<string> { "to1@amazon.com", "to2@amazon.com" }, CcAddresses=new List<string> { "cc1@amazon.com", "cc2@amazon.com" }, BccAddresses=new List<string> { "bcc1@amazon.com", "bcc2@amazon.com" } } }

I am getting delivery of ToAddresses "to1@amazon.com", "to2@amazon.com" but not getting of CcAddresses and BccAddresses.

Is there any reason or configuration to get delivery of CcAddresses and BccAddresses?
