The activities section in our UI at www.constantcontact.com will display certain activities that are not truly 'bulk activities' in the sense that bulk activities through our API are. For this reason you will see certain activity types that will display in the product, but are not returned through the API. I apologize for any inconvenience that this causes. If you have any other questions or concerns regarding this, please let us know and we will be happy to help. Thanks.
