Please do feel free to contact our support team for assistance with this as Eric noted, but I just wanted to reply to let you know that the routing notification is suppressed when a technician routes a ticket to them self. If you are routing tickets to yourself to test whether or not the routing notifications you've configured via the SLA feature are going out it will seem that they are not, but if you have someone else route a ticket to you, you may find that they are being sent.
