The internet has changed a lot since its inception, moving from static websites to the dynamic place we've come to take for granted today. While emails may look fancier today than they did 30 years ago, they've still been very limited so far as user interaction goes — you can click a link to visit a site, but that's about it. Enter: "dynamic emails." Google first introduced them to developers as AMP for email, with plans to roll out broadly last year. While the company missed that target, we saw evidence in a recent APK teardown showing work was still pending. Today Google finally announces availability of dynamic emails.
