Topics

Topics represent distinct subscription categories (e.g., Product Updates, Newsletter, Security Alerts).

Managing Contact Preferences

Instead of an all-or-nothing unsubscribe, topics allow contacts to opt out of marketing communications while remaining subscribed to critical product notifications.
