Is anyone else comforted when they see an email signup is through list-manage.com? I trust that at absolute worst I can email MailChimp and they will actually act on my desire to unsubscribe, and I know that almost certainly that won't be needed because of their enforcement of reasonable unsubscribe. I find it ironic because it seems they wanted as anodyne a domain as possible so they wouldn't clash with their customers' brands.
