The email you have received from Humanitix is your ticket (keep it safe).
You will have not received a QR code or tickets. This is to minimise scamming and copies of QR codes circulating.
Fear not, Strawberry/Humanitix will be in touch closer to the event with your digital tickets and QR code.
Note: If you're looking to resell or action a name change, you do not need access to your ticket. You can do this at any time via the manage order button on your confirmation email and using the resale tab.
