Email A/B testing is always about marketing and trying to manipulate users, in my experience. If the content is the same, but a different button gets more clicks, it's hard for me to believe users are finding a benefit in that. I think it's far more likely that the content isn't all that compelling, but the UI tweaks managed to tickle some part of the reader's subconscious in the right way for them to click. In other words, emails with quality content don't have marketing teams running them. This is pretty much like all targeted advertising. The benefit to the company is very clear, but I don't think I'd be missing much if email analytics went away. Just as a personal opinion that I'm sure plenty of people disagree with, I dislike it when products are hyper-customized based on a lot of analytics. For instance, Netflix has a ton of data on me, but all of their tests and micro optimizations make me use the app less. I would much prefer their product if they threw all of that info in the trash, rolled the UI back 5 years, and showed me more generalized start ratings again.
