Share suppression lists from parent business units to child business units in Email Studio.
Suppression lists compare subscriber lists against the master publication list, which controls opted-out subscribers. This comparison ensures that only the subscribers who opted in for the publication receive the publication.
Note Subscribers see a list of publications when they visit the subscription center through an
email sent from a business unit. The publication list includes both the suppression lists created
by the business unit and the suppression lists shared with the business unit.
