Can't you just create additional, unassociated Google Accounts? It's probably good practice for any registrar anyhow. I ended-up doing this for GANDI after receiving this out of the blue: It is very important that you confirm that your email address works and that we can reach you at this address. If we do not get your confirmation, the domain names that are associated with this email address will be deactivated on 2016-08-12 Consider that if the e-mail address hadn't worked then I wouldn't have had any domains after a week and wouldn't have known why. Not a risk that I can accept. So I split each domain onto a new 'handle' so that there's less risk of total loss, and now I am planning to spread across other registrars.
