Add Cron job and Extended Email Notification in Jenkins

Hello,
I want to add Email Extender and Cron Job to my Jenkins during the built.
So every time i run the DC, the pod which is creating Jenkins also Create Extended Email Notification setup and Cron job inside it. Now its more time consuming to manually setup the Plugin and Cron job in Jenkins.
If someone can share a sample of code to perform a certain job.

Regards
