This is the name for a person or group of people who have voluntarily decided to become notified of updates from a specific source of content. Amongst other things, users can subscribe to YouTube channels to become notified of new content there, or to a mailing list in order to receive emails from a particular source.
Subscribers are the life-blood of many forms of marketing as they constitute an actively interested list of possible consumers. Proper management of a subscriber list can sometimes, therefore, make or break the success of a campaign.
