When you unsubscribe (click the ''Turn off this request's notifications" link at the bottom of the email), you will no longer receive any notification emails regarding a given ticket.
However, if you create a new ticket, we will send you notifications about this new ticket unless you decide to unsubscribe from such a thread as well.
When you are logged in to our portal, you can choose whether to subscribe or unsubscribe by clicking "Get notifications" or "Don't notify me" on a given thread page.
Also, at your request, our support can remove your email address from the 'Unsubscribed' list to make sure the system continues to send you all the notifications required.
