Anyone have any tips with AMP for Email?

Been looking at AMP for Email recently and thinking about building out my own emails using AMP. With Ai making everything easy now, it seems pointless to pay hundreds/thousands in monthly software costs, when you can just make your own (if you can be bothered).

Obviously for ecom, first thing would be to generate reviews from within the email itself rather than a click through.

Anyone have any experience? Whether their own build or even just using a service that already exists. Any tips or advice?
