When I saw the AMP for email announcement I was not excited, but I did not get the online dread until I read this post. The immutability of my email has saved me so many times. I also have this feeling (which may be unfounded) that emails are "proof" of something when I get into a dispute. If my email can change or rot underneath me, I will have to change the entire way I operate online. I like AMP websites (at a basic level they're fast and that's all I care about) but I have no interest in AMP email. I hope I can opt-out of it.
