Non-promotional emails, on the other hand, will be less sales-driven and timely, and more focused on building relationships and providing value to your customers. While promotional email campaigns generally tend to yield a higher click-through rate, non-promotional messages allow you to see what interests your email subscribers so you can segment accordingly. You can follow up later with more targeted messages that help to nurture your relationship with these audiences.
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.
