The label level mailing list is not a rollup of all your individual artists’ mailing lists. Fans joined a mailing list for a specific artist, so we do not combine all of those into a single label mailing list. However, there is a) a checkbox in the checkout dialog that invites the buyer to join your label mailing list, and b) a Follow button on your label site, which adds the fan to your mailing list, and means we notify them of all your releases via email as well as a story in their music feed.
