"AMP for email allows senders to include AMP components inside rich engaging emails, making modern app functionality available within email. The AMP email format provides a subset of AMPHTML components for use in email messages, that allows recipients of AMP emails to interact dynamically with content directly in the message." About AMP Email
^^ Agree with Justa that emails have been traditionally quite rubbish, heh - like 99% of the emails I receive aren't even responsive - it's 2019! I am optimistic with AMP's emails, hopefully they will better them.
