Deploy Adobe CC to team members without email address

I have purchased seven Adobe CC seats and have a question about deploying those seats to seven workstations. Each user does have their own workstation, however, most of them do not have their own email address. Our art department has one email address (i.e.- art@example.com). How would I deploy those seven seats to the seven workstations? Off the top of my head, I am thinking that I will just have to open a dummy email account for each workstation, but I would love a better solution, if there is one.
