Entityform: email submitted form to someone who is not admin?
go to admin/config/workflow/entity_rules/entityform_submission and clone "Entityform Notification Email Submitter" or "Entityform Notification Email Admin", edit accordingly. If that does not works, please add a custom rule (admin/config/workflow/rules): 

event: After saving a new entityform submission
Condition: Entity has field: [entityform], Field: token of your field
Action: send email, use the token for your email field or any email you want.
