Serving up dynamic content based on a person's previously viewed content
Is it possible to use dynamic content to serve up a different image/blog based on whether or not a contact has already viewed and/or been served that blog elsewhere? So if the user has viewed Blog A but not Blog B, display Blog B. If user had viewed Blog B but not Blog C, serve Blog C etc. And then I'd probably need an option for it they've viewed all of the possible blogs already, like driving them to the website or something.
