mantis emailing issues?

[incrediblehelp]

OK people can someone tell me how I can make sure "management" gets emailed every time us little workers update and create tickets? The management users probably never interact with tickets directly, but they want to get notified though email when tickets are updated are closed. Any ideas? Right now only the people that create the ticket, are assigned to the ticket and make updates to the ticket are getting emailed when updates and closures take place.
