Zalo Notification Service (ZNS) is the official transactional channel inside Zalo, and in Vietnam it dramatically out-performs SMS and email. Real-world open rates for F&B brands sit at 78–92% within four hours of delivery, with most opens happening in the first 30 minutes.
The metrics worth tracking beyond opens are CTR (healthy 14–24% on a clear single-CTA promo), 7-day redemption rate (healthy 6–11%), and unsubscribe rate (healthy under 0.8% per send). Send-cadence above 2 ZNS per week per member starts compressing all of these.
One CTA per ZNS
Two-CTA messages cut CTR by roughly 40% in F&B. Pick one action and route everything to it.
Send at intent windows
11:00–11:30 for lunch promos, 16:30–17:30 for dinner promos, and 09:30 for brunch on weekends. Off-window sends lose 30–50% of their potential redemption.
Personalise the offer, not the salutation
Members ignore 'Chào anh Nam' but respond to 'Bánh mì gà yêu thích của bạn − giảm 20% hôm nay'. Use POS history, not just first name.
FAQ
How does ZNS compare to Zalo OA broadcast?
OA broadcast has roughly 12–18% reach due to Zalo throttling. ZNS is delivered to every approved recipient with very high open rates, but content must match a Zalo-approved template.
Does PEKO send ZNS natively?
Yes. PEKO's ZNS engine ships with pre-approved F&B templates for tier upgrade, reward expiry, almost-there, and birthday, and reports the full open / CTR / redemption funnel per send.
The PEKO ecosystem
PEKO and LOOP are two products from the same company. PEKO is the AI retention layer and runs alongside the POS you already use. LOOP is the AI-native POS that covers operations: recipe-level inventory, staff shifts, table plans and the kitchen display. Each works on its own, and run together they share one dataset, so nothing has to be entered twice. See PEKO + LOOP in one ecosystem

Answer
Broadcast or transactional messaging — which should an F&B venue use?
Both, for different jobs. Broadcast to followers is free or near-free and good for news; transactional templates cost per message, reach anyone who gave you a number, and are what you use for anything time-critical.
Answer
How do I calculate point liability for my loyalty program?
Point liability = outstanding points × redemption rate × cost per point. For most F&B programs that's 0.3–0.8% of trailing-12-month revenue. Tracking it monthly prevents the year-end surprise that has killed several Vietnamese programs.
Answer
How do you capture customer contact details at a cafe without slowing the queue?
Take the cashier out of it. A self-scan QR where customers already wait, with a reward claimable on the next visit, converts 40–60% of transactions without adding a second to service time.
