Campaign Monitor, the email marketing web service announced an iPhone version of its client site. A simple elegant user interface that hardly feels like something on the web (built using the jQTouch plugin by David Kaneda).
Sure not everyone needs an email marketing service, so it’s a good thing there’s a free sign up for you to tinker around with the web app as well as the desktop experience of the service (which is pretty good on its own). If that’s what you feel like doing today, that is.
