Email notifications available to all users, here are some of the rules.New Users Always On
Every time you create a new admin/client/employee their "Notify By" options are all set to On. To turn them off either an Admin or the User has to un-click his or her profile settings and save them to stop receiving them.
Admin Receive Notifications
For an admin to receive notifications, they must be in the "Project Users" list. And of course their notification settings must be on. The reason for this is to prevent unnecessary notification emails to the Admins who may not be overseeing or involved in a project.
Changing Outgoing Messages
You can change the text of your outgoing messages in the settings panel, as the Master Admin.
