The same problem happens in the Submission admin:

django.urls.exceptions.NoReverseMatch: Reverse for 'newsletter_submission_submit' with arguments '('',)' not found. 1 pattern(s) tried: ['admin\\/newsletter\\/submission\\/(.+)/submit/$']

This problem is triggered when there is no new object (e.g. because of a validation error). The template then tries to lookup a link (either preview for Message or submit for Subscription and fails.
