The Unsubscribe and Modify Preferences forms are hosted on Pinpointe's site. The layout is fixed at present; This feature would allow you to upload your logo and select colors so that the page will better fit with your branding.
This would be a nice enhancement. Right now the one-click unsubscribe page doesn't have any ability to customize the landing page or survey form. We market internationally and having the ability to customize and add localization would be beneficial. See example attached.
