Implementing Listener for DataHub Events in Hybris

Hi Experts,

Requirement: Trigger a notification once all the products are loaded in hybris through datahub i.e all publications are completed. I am trying to use PublicationCompletedEvent and write a listener for it to achieve the task. Can someone please provide me better clarity as how we can achieve this functionality and trigger a mail from hybris itself?

Thanks in advance!

Regards Rahul
