I am using rails_admin and recently integrated devise_invitable to it . The app is using rails 4 and i followed the guides to integrate it . All went well , even the admin side of rails admin shows that uninvited users are signing up , but the users don't receive mail .

How users are invited? create_creative_user is not a devise invitable action
