If you are flagged as the recruiter owner for a job, you will automatically receive an email whenever you have a prospect. To change this setting across all your jobs, go to the Settings tab, and then select Prospect notifications. From here you can change your notification schedule, or opt to turn notifications off altogether.

To stop getting notifications for a single job, you should remove yourself as the owner and reassign the job to another recruiter.

If you aren't the owner but you're receiving prospect notifications, then you have flagged this job as one you'd like to watch. To stop watching the job, click on the title to open the job listing. Then from the More drop-down menu, select Stop watching.
