Can anyone explain what this would look like? Just an HTML email but with parts of it hosted on AMP’s CDN? Or the whole email is hosted on AMP, and non-AMP email clients just have a link (and cannot view their email without clicking on a link, and leaking the fact they viewed the email?) Would it be possible to make a filter in FastMail that automatically deletes these emails? I can imagine spammers would love to send “You need an AMP client to view this email, click here”. Plus the point about privacy above. Edit: I’d want it to send a reply, as I can imagine anyone with a Gmail account might be blocked from sending me an email. Possibly any companies on the AMP bandwagon. This might be the push I need to get round to writing an IMAP gateway that strips HTML and only serves text/plain to my email client. I don’t need more HTML and tracking bullshit in my emails.
