Send email to a contact via workflow rules

Send email to a contact via workflow rules

Here https://www.zoho.com/crm/blog/zoho-crm-the-new-improved-workflow-rules.html 
is mentioned that in workflow rules emails can be sent to leads and contacts as well.

However, when I go to Automation - Workflow - Alerts - Configure Alert
there is a feature to send email alerts only to company staff.

Can you advise me how to send emails to contacts on a picklist field change trigger?
