Email List Manager

Changes to Email List Manager

Starting Thursday, September 29, requests for new email lists will be fulfilled by Google Workspace Groups and Sympa lists will no longer be used to fulfill new list requests. This change will not affect the immediate use and management of Sympa lists, however, this is the first step in eventually retiring the Sympa Email List Manager service and fully migrate lists to Google Groups. Learn more about the change from our news story. 


Email List Manager is a list software powered by Sympa that allows users to subscribe and share messages with other subscribers. The list is managed by specific list owners and can be managed via email commands sent to or through the Email List Manager web interface .
