Number of free users for Zoho Mail Lite

Number of free users for Zoho Mail Lite

Hello,

I registered for zoho lite with my personal address in order to create email accounts for my domain using the lite version at first to try it. On my control panel, in the user list, I see the 3 domain based accounts I created plus my personal account which is also the admin account.

Since there is a 3 user limit for the free edition, does my personal account count in this number? If so, how can I remove it? 

Thanks
