I like "A/B test your emails" better. I understand the problem of having to rewrite emails over and over again that are delivering the same message for the same goal, but need to be tailored to some specific-case scenarios. You might be entering into the email newsletter space with the more functionality you roll out so I would think it best to concentrate on those instances where you are doing customer development type stuff. The need to reach out to people in a very personal way entails that I DON'T spam them from an email newsletter, but yes I would want to approach it in a systemized fashion. Have a way to iterate on emails and refine your pitch - I like that.
