Hi Sneha,

You could configure the application to send an email alert when a customer submits a ticket by adding the agents list under 

 Admin -> Email notifications -> Agent notifications -> 'New ticket created' notification. In this page, scroll down to find the Notify agents field. Please add all the agent names you want and save the changes. 

Kindly check this and let me know if this is clear.

You could also create a dispatch'r rule to do this and other tasks on a ticket once created.
