User Status Alias is located on Settings > Users > Status Aliases
The User Status Alias is just a way to have a different name for the existing statuses:
You can, for example, create some User Status Aliases been alias of the Active status.
Changing the status of an existing Client to one of the newly created User Status Aliases will not notify your client at all yet. However, you can then use our Notifications system, to automatically send emails or create support tickets to the respective users when they are on a certain status.
You can find them under: Accounts > Contact Users > Notifications
There, you will see 2 links:
After configuring the service and the templates, now you can create the respective Notification rules under: Accounts > Contact Users > Notifications
Once done, when Auto Mailer runs, it will evaluate the Notification rules and do the respective Action you configured for them. Clients will not be notified twice while they continue matching the Notification rule, so if they continue in the same status, they are notified only one time. Once you change them to a new status, if the new status is matching a Notification rule, that rule will notify him/her, and will now be able to be notified with the previous Notification rule when he/she goes back to that previous status.
