Registering Device without associated email

I’m in a program utilizing the PurpleAir sensors. The people in the program last year bought the sensor, but never registered them. Now, my group is trying to register them, but do not have the associated email. Is there anyway to register the PurpleAir without needing the associated email? Any information is appreciated, thank you!
