send email on certain status/action like promote

[henke.mike@…]

Is there a way to create a joinable_group like OnPromote then email the group when any ticket is advanced to a status/action. This example would email anyone that joins the group when a ticket is moved to close or promote:

[announcer] joinable_groups = onpromote onpromote.status = closed, promote

Another other useful email triggers might be Type, Priority critical_tickets.type = defect critical_tickets.priority = critical critical_tickets.statu s= new

This would email the critical_tickets group when a new ticket is added as critical and defect.

Thanks,
