Online Documentation for SQL Manager for SQL server
Managing notifications
The Notifications tab allows you to specify actions that the SQL Server Agent service will take after the alert fires. Alert notifications ensure that database administrators know when events/errors occur and which measures are taken in response.
The main area lists all currently available operators. Specify the method by which an operator is to be notified: E-mail, Pager, Net Send. Set the corresponding flag next to the operator name.
