Apparently, CNN has shut down Ms. Roesgen's email. They are now advising people to email CNN Executive Vice President Ken Jautz instead, at: email@example.com
And don't forget her boss, Philip Kent, the Chairman & CEO of CNN, at: firstname.lastname@example.org
But it's likely that CNN will turn on Ms. Roesgen's email again some time soon. We'll just keep checking over the next week or so, and if it looks like it's operational again, we can email her then.
