This email from Amazon Local is short and sweet, with just one CTA: click through this email to tell Amazon what you like and dislike. That way, the deals they send you going forward can be more in line with what you're likely to actually want. What's wonderful about this experience is not just that they asked, but also how consistent the experience is from email to landing page. Take a look at the email below, and the landing page that follows.

Please forgive me if I missed this in some of the comments and replies, but I saw nothing on Infusionsoft or Marketo. I was expecting to see both in your analysis, but nothing was mentioned, save for the remark early on that Active Campaign has rocketed past Infusionsoft in the marketplace. Is it because you consider them outside the “Email Marketing” space which was the subject of your analysis?
Don’t talk down to people. I think this should be obvious. But looking at the email offers I get, clearly it isn’t. Don’t tell people, “Not buying this product would be idiotic!” or “Only a fool doesn’t understand the value in this service.” This whole email marketing strategy relies on you making people understand the value they can get from you. And sometimes that means making people see the downsides of not buying. But you can do that in a friendly, respectful way.
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.
