Cortana has a huge amount of schema.org integration. Yahoo is onboard but I have no idea what they do, whether email factors in to what they do atm.
I'm insulted Google is whitelisting schema.org markup. Their guidelines also mandate that you already send hundreds of messages a day, which is hostile as fuck and disgusting. That's incredibly poor plutocratic bullshit handling, and flies hard in the face of what the web is. What a pity.
