use same primary email address for multiple zoho accounts

use same primary email address for multiple zoho accounts

Hi,

I have children I want to sign up for email addresses.  The idea of using Zoho is that I don't want to open gmail,yahoo, etc. accounts for them to be tracked and recorded.  So I had planned to open their accounts using my work email as the primary address.  But it seems that there can be only one Zoho email account for any given primary address.  So that would mean setting up a gmail account for them to open a Zoho account, which defeats the purpose of the Zoho accounts.  Is there any work-around or way to open multiple accounts with my work email as primary?

Thanks,
Brian
