+Feature: Emailing petitioner supporters
+  In order to keep petition supporters up-to-date on their petition
+  As an admin user
+  I want to send an email to all petition supporters
+
+  Scenario: Sending an email to all petitioners
+    Given an open petition "Ban Badger Baiting" with some signatures
+    And I am logged in as a sysadmin with the email "[email protected]", first_name "Admin", last_name "User"
+    When I am on the admin all petitions page
+    And I follow "Ban Badger Baiting"
+    And I follow "Email petitioners"
+    Then I should be on the admin email petitioners form page for "Ban Badger Baiting"
+    And the markup should be valid
+    When I press "Email 6 signatures"
+    Then the petition should not have any emails
+    And I should see an error
+    When I fill in the email details
+    And press "Email 6 signatures"
+    Then the petition should have the email details I provided
+    And the petition creator should have been emailed with the update
+    And all the signatories of the petition should have been emailed with the update
+    And the feedback email address should have been emailed a copy
