I've gotten 7 emails in the past hour of the same message
Dear FireCloud user,
Heads up! New data has been added to Cellopedia_CIRM_Eggan_iPSC_WGS.
Thanks for using FireCloud!
You can turn off notifications for a workspace by going into that workspace in FireCloud and clicking the little bell icon in the upper left corner. There should be a blue slide bar that you can click on to turn off notifications when data is added or changed.
You receive notifications by default for workspaces that are shared directly with you. A new notification is sent out every time data is added or changed, which leads me to believe that the workspace you mention is being actively updated. If you are still receiving emails after turning off notifications, let me know.
