Contact
A small operation, so there is one address and a form. Both are read by a person.
The private beta
The application form is the right channel. It asks the questions we need answered, which an email usually does not.
Everything else
Press, partnerships, questions the FAQ does not answer, or a correction to something on this site.
Security
For a vulnerability or a security concern, use the security address and read the disclosure policy first.
Please do not send confidential documents to any of these addresses. Nothing on this site is a secure channel, and there is no reason for us to hold your material.
