Export-Option Email-adresses of Customers

There is no way of exporting email-adresses of all (active, inactive, or both) customers in the Enterprise Users dashboard.
Customer Emails are not available in reports either.
I think it is rather common to need to communicate with all customers, and to be able to contact directly those who are active/inactive.
I would appreciate not to have to type about 400 emailadresses on my own. :-)
