# FastStats email response gatherer

PeopleStage uses the FastStats Email Response Gatherer (FERG) to gather ESP responses, via an API call, into a staging table which it can use in "real time".

## How FERG works

PeopleStage will allow you to define and implement marketing process flow diagrams that will react to the responses you receive from the ESP.

> A FastStats build does not need to take place for you to use Broadcast Interactions in PeopleStage.
