+##### Mailing List Permissions
+
+Permissions to send mail to the [kubernetes-announce](https://groups.google.com/g/kubernetes-announce) are managed in Google Groups. To request access please reach out to the [list owners](https://groups.google.com/g/kubernetes-announce/members?q=role%3Aowner) in slack.
+This is only needed if you plan on sending mails manually (not through sendgrid).

 #### Skopeo
 
 [Skopeo][skopeo] is a command line utility that performs various operations on container images and image repositories. Skopeo is not required for performing branch management tasks (if needed, Docker and other relevant tools can be used instead), however, it might be referred to by other guides. If you want to install Skopeo, you can follow the [official installation guide][skopeo-install].
