Redeeming Marketmuse codes without website domain

I purchased a couple of codes for Marketmuse from Appsump back in Feb but appartently I can't redeem them without a website domain. I figured i'd have one set up before they expired but they expire next week and i dont think i'll have one before then.

Does anyone know if there is a way around this to redeem the codes without a website domain?

Can I just set up any domain for now and cancel it after ive redeemed them or is that site forever linked on marketmuse? Thanks
