Hello Divya, 

You need to have Project Admin or jira Admin permission, go to project setting, Notification and from here you can control the events and to whom you want to send notification to.

Thanks

Hi @divya reddy 

Please provide a bit more information...  Is this for a company managed project or a team managed project?

Each type of project has different notification options.
