Menu item admin/content/newsletters for editor

Hello,

I have a problem on the permissions with the simplenews module. When I use the administration interface with the admin account I see a menu link Newsletters (admin / content / newsletter). If I login with a editor account this link is not present. Editor can't manage newsletters.
In the permissions page I have checked "administer newsletters" for the role editor.

How can I get the menu link for the editor role?

Thank you.
