Sender Profile and AMPscript Lookup are the functionalities that accomplish the requested configuration. A Sender Profile allows you to define the From Name, From Email, and Reply Email for an email send. You can use AMPscript Lookup function within a Sender Profile to dynamically populate these fields based on data from a data extension. For example, you can use Lookup function to retrieve the sales representative's name from a data extension based on the subscriber's ID and use it as the From Name. A Delivery Profile and a Send Classification are not related to personalizing the From Name. Subscriber Attributes are not stored in a data extension.
