To stop email notification for a user regarding PR release in workflow

Hi All,

I am new to workflow.

I need to stop an email notification for a user who receives it for PR release.

I checked earlier posts which stated some send email steps in workflow and extended notifications.

But I am not aware of any of this things.

Can you all please help me in resolving this? As i hardly know anything about workflow.

How can i check where this email notification gets triggered or from where it picks the user id?

Your help would be appreciated.

Thanks.
