is zoho mail without hosting free ?

Hi,

I would like to know if my current zoho mail account is free or do i need to setup a domain hosting or get a paid subscription.

Reason why i ask is that i couldn't

1) see from the singup it was free
2) get current mail box size limit
3) see that the current account is trail or i need to subscribe / get hosting

Thanks,
Ryu.
