Zalo OA marketing
Written by PEKO Team.Last updated: 2026/05/21.
Zalo OA (Official Account) marketing is the use of Vietnam's dominant messaging app to reach customers with loyalty, broadcast, and 1:1 conversational messages.
Published: 2026/05/01
Zalo is installed on 75M+ Vietnamese phones — making OA the highest-reach owned channel for any F&B operator in Vietnam. Read rates routinely hit 70–90%, vs 15–25% for email.
Effective Zalo OA strategy in F&B combines (a) a loyalty mini-app for stamp/points, (b) automated win-back triggered by churn signals, and (c) targeted broadcasts for new-menu launches — all governed by Zalo's anti-spam quotas.
PEKO integrates natively with Zalo OA: customers join your loyalty by scanning a QR at the table; from then on, every win-back, birthday, and new-menu message ships through Zalo with full delivery tracking.
FAQ
How much does Zalo OA messaging cost?
Free for replies inside the 24-hour window after a customer message. Outbound broadcasts are quota-based and priced per impression — typically far cheaper than SMS in Vietnam.
Can I use Zalo OA without a developer?
Yes — PEKO and similar platforms ship pre-built Zalo OA flows for loyalty, win-back, and broadcast that you configure from a dashboard.
