I've disabled notification to the requester when creating a ticket, but sometimes I really do want to notify the client, so what I do is just reply to the ticket, so that the requester gets the ticket in his mailbox.
I've just migrated from Jitbit, where there was a check box next to the requester field in the ticket view. When checking this box, the requester would get notified. Is there a similar option in Freshdesk?
