I believe that she knew this message will be "leaked". It would be close to stupid to think otherwise. Hell, this message was written with leaking taken in account.

It's a journalist's job to get the internal story, even if that requires exploiting various forms of petite disloyalty. Also, a rah-rah message this generic was written with the expectation it would be leaked.

And, Swisher as a journalist would likely expect (and perhaps even respect) if her own correspondents leaked her own emails, if and when it could advance a story of industrywide interest. Journalists aren't especially thin-skinned, naive, or hypocritical about such things.

Interestingly, Swisher's spouse is a VP at Google.
