How to manage multiple domains with one Zoho account?

Hello! I have a Zoho account that I've had for years with an @zoho.com email address. I wanted to move one of my business emails to Zoho so I upgraded to the Standard account and added my domain. Everything worked fine up to this point.

My problem now is that, as far as I can tell, I only have one Inbox for both my @zoho.com address and my @mydomain address. Is this correct?

My assumption was that this would be like the Google Suite in that each domain would have it's own inbox and essentially act as it's own account. Is this incorrect?

Finally, I have three different businesses, each of which currently has it's own Google Suite account. Is the only way to achieve the same thing with Zoho to have three separate Zoho accounts, each with their own subscription fee? If that's the case, that's fine. I just wanted to make sure I wasn't paying for multiple accounts if I didn't have to. :)

Thanks for helping me understand!
