Modify Mailchimp Multisite for ADMINs/Editors of sub blogs only?

Is there a way to make the Mail chimp plugin only add people in the network who are Editors or Admins?

Or some other plugin you have or could suggest?

The intent is to only email the multiste admins and editors with news and feature releases, and not bother the general public (or fill my mailchimp list up with garbage)
