We plan to let technician to using the email create the incident request assign to them self, close ticket and update ticket via E-Mail Command, but there are no notification email to technician(i have tick the  Alert technician by e-mail when a request is assigned.).

It will send notice email to technician if we manually assign it to technician from the web portal. Is there any possible solution that allow it will send notice email to the technician even using the email create request assign to them self?

And how to set the "Service Categories" can parse by the email command when the email received?
