My point is that they are not breaking the embargo by publishing the contents of your initial email.

Whatever you send in the initial email is decidedly not embargoed. Totally get that the risk can be worth it, but you're implying in this post that the information is actually under embargo when sent before explicit agreement.

Journalists take you more seriously when they see you know how works: https://twitter.com/ceodonovan/status/773966062974926848
