From SendGrid's Facebook https://www.facebook.com/SendGrid/posts/10151502570463967

Effective immediately, SendGrid has terminated the employment of Adria Richards. While we generally are sensitive and confidential with respect to employee matters, the situation has taken on a public nature. We have taken action that we believe is in the overall best interests of SendGrid, its employees, and our customers. As we continue to process the vast amount of information, we will post something more comprehensive.

By verbal I meant spoken, in person or over the telephone. there was some confusion earlier about the authenticity of the FB posting.
