Mailing Lists

The IVS mailing lists are part of the NASA-wide Agency Mailing List Service (AMLS). In May 2021, AMLS was migrated to a new host organization as well as upgraded to the newest list manager. For the migration all membership information and list options were rolled over from the old to the new lists. The mailing list names did not change.

At its new home, the general public (i.e., non-NASA users) is no longer able to access the web interface, including the list archives. All subscription requests are handled via email either directly to the list or to the list manager. In order to subscribe and unsubscribe send a message to and, respectively. The subscription request has to be approved by the list manager. The list manager(s) can be reached directly via For instance, to subscribe to IVSmail, send a message to (no subject or text in the body is required).
