how many emails can be sent per day using the workflow alerts?

Hello everyone,
We have created workflow rules into automation space inside the CRM, and we have a question: how many emails can be sent per day using the workflow alerts? we read your docs at this link https://help.zoho.com/portal/kb/articles/how-many-emails-can-be-sent-per-day-using-workflow-alerts.

This is the case: 

the company has three accounts:

1) A (the owner)
2) B (2nd account)
3) C (3th account)

B writes the rule that if B add new leads, these one recive an emails with informations. How many emails can be sent from the CRM? only 100 that is the number of email per user, or 300 that is the sum of 3usersx100?

Thanks in advance.
