System not email requester when a ticket is udpated

System not email requester when a ticket is udpated

I have gone into Setup > Automation > Notifications and checked the "Acknowledge Requester by Email when the request is updated" but the requester does not receive an email?

I sent an email to the system and it automatically created an incident, and emailed me back stating that a ticket was created. I then assigned the ticket to myself, and received an email that the ticket was assigned to a technician, then I added a note to which the requester can see, I have changed the Priority, changed the level, changed the status but still no email.

Thoughts?

Thanks
