Anthropologists, sociologists and historians have used mailing lists as fieldwork.[6] Topics include TV series fandom,[7] online culture,[8] or scientific practices[9] among many other academic studies. From the historian's point of view, the issue of the preservation of mailing lists heritage (and Internet fora heritage in general) is essential. Not only the text of the corpus of messages has yet to be perennially archived, but also their related metadata, timestamps, headers that define topics, etc. Mailing lists archives are a unique opportunity for historians to explore interactions, debates, even tensions that reveal a lot about communities.[10]

I think this email also makes quite a brilliant use of responsive design. The colors are bright, and it's not too hard to scroll and click -- notice the CTAs are large enough for me to hit with my thumbs. Also, the mobile email actually has features that make sense for recipients who are on their mobile device. Check out the CTA at the bottom of the email, for example: The "Open Stitcher Radio" button prompts the app to open on your phone.
Dynamic segmentation – As alluded to earlier, you can’t just send out a generic message to everyone on your list. While basic demographic data can be used to segment your list, that’s far from taking the dynamic approach. Automation tools can help you segment your list as they go through the funnel, allowing you to send personalized messaging depending on their actions and behaviors.
