What is the most effective and efficient way to track content downloaded on a contact-by-contact basis?
I want to ensure that our email marketing efforts are not pointing prospects to content that they have already downloaded. One obvious way to avoid this would be to create a check box field for each piece of content and have it checked off as soon as the content as read. However, this would obviously require that a ton of new fields be created. Does anyone have a more efficient way to manage this?
