Preference Orchestration
Maps each subscription topic configured in Ketch to a specific subscription group in Braze. Opting in or out of a topic in Ketch updates that exact subscription group in Braze, on the channel it governs. A global unsubscribe goes further: alongside opting the person out of every configured topic, Ketch also directly changes their account-level email subscription status in Braze from subscribed to unsubscribed. Re-subscribing from a global opt-out reverses the account-level email status, but doesn't automatically re-opt someone into individual topics; those need to be chosen again, which keeps re-subscription from becoming a backdoor into channels the person deliberately opted out of.
