Explanation:

Publication Lists let you define distinct categories of communications—such as newsletters, promotions, or alerts—and tie your Data Extension sends to those lists. When subscribers visit the Subscription Center, they see each Publication List and can opt out of specific categories they no longer wish to receive. Marketing Cloud then manages their unsubscribe status on those lists without affecting other sends. Suppression and Exclusion Lists are for send-time filtering, not subscriber-controlled preferences. By using Publication Lists with your Data Extensions, you enable self-service unsubscribe management for each email type while keeping your broader mailing capabilities intact.
