Not a best practice by any means.

Run a sql agent, set the task to powershell. I believe you need to be admin on box, etc... So not meant for large organizations.

try {

Get-Service MSSQLServer -ComputerName (insert your servername here) -EA stop

}

catch {

Send-MailMessage -To "stadman@test.org" -Subject "(insert your servername here) sql service is not running." -Body "Please consult the system event logs." -SmtpServer mail.test.org -From sqlchecker@test.org

}
