Sending a triggered send to multiple To/CC/BCC recipients via the API

The BCC functionality needs to be enabled on your account first. Talk to your account rep for details. You can see the note about it on the bottom of this page: http://help.exacttarget.com/en-US/technical_library/web_service_guide/objects/triggeredsenddefinition/

The CC/BCC functionality is an additional feature that is typically not enabled by default.

You can check to see if it is enabled by going into the TriggeredSend section under the Interactions Tab, go into the TriggeredSend Definition that is defined and if the feature is enabled then you will see fields for CC and BCC there. If not, then you will need to contact your ExactTarget relationship manager in order to get that enabled.

By default the CC/BCC fields on the TriggeredSend Definition are designed to be populated with a static value when the definition is created so that every email sent through that definition will be copied to that address.

It is possible to setup a definition in order to send to dynamic CC/BCC email addresses which are defined in the API.

In order to make the CC/BCC fields dynamic:

1. Create a profile attribute to hold the dynamic value, for example call it "BCCAddress"
2. Update the TriggeredSendDefinition so that the BCC field contains a reference to that profile attribute using the substitution string format: %%BCCAddress%%
3. Make sure to publish the TriggeredSendDefinition after making changes if it was already published
4. Update the API request so that it passed a value for BCCAddress as an Attribute on the Subscriber object similar to how you are likely passing other profile attributes. If you need to have multiple addresses receive the CC/BCC then a semi-colon just needs to separate them.
