Using the RaiseError AMPscript function allows a developer to handle errors when necessary data for building an email is missing. The possible outcomes of using this function include:
* The send fails (A)- The entire email send can be stopped if a critical error is encountered.
* The email is not sent to the particular subscriber (B)- The send can be aborted for specific subscribers who do not have the necessary data.
