About alias emails

Hi there,

I'm really interested in Zoho mail and have an intention of using it in my business. However, I've found myself with a couples of questions relating to alias emails:

1. About the "Free plan: 10 free users", I wonder if my alias emails are considered as my new users, which means that my 1 user and its 9 alias emails will be full for the free plan? Or no matter how many alias emails I have, Zoho will count them all as my only one user?
2. In case that one of my user email is deleted and another one is created, Zoho will see this situation as I have 1 user of 2 users in total?

I'm looking forward to hearing from you as soon as possible. Thank you in advance.
