One platform does not mean one channel set for every market. In Vietnam, marketing teams run Meta and Zalo. The English door is Meta and Google. Zalo is not a default channel on the English product.
Leads from any connected channel land on the same record. The closed-loop does not change. Connectors and site copy do.
Why a pack
ASEAN or English buyers do not need Zalo on the hero. Vietnam buyers need Zalo on the Ads page. A pack keeps the position: specialized by market, not “every channel everywhere.”
