AMP AND WHY EMAILS ARE NOT (AND SHOULD NEVER BE) INTERACTIVE

Summary from the TLDR Web Dev newsletter

Google's AMP for email tried to modernize email by adding interactive features, similar to its earlier AMP project for mobile web pages. AMP for email required significant effort to implement and support, only worked in a limited number of email clients, and eventually failed to gain widespread adoption. While Google still uses AMP internally as "Dynamic Email," the project has been largely abandoned.
