I think you are misunderstanding OP. At least I assume that Zoho will not be able to change Google's policies, otherwise that would truly be outstanding customer service.

For me you're not the problem, you just have no power here. Google services are more convenient to use with Google email accounts, they are more prevalent and there is no point in burdening an organization with another email provider if there is a choice.
