Zalo for Customer Support

Zalo is Vietnam's dominant messaging platform with 79.6 million monthly active users and over 2.1 billion messages sent every day (VNG Corporation, Q4 2025). For any business serving Vietnamese customers, Zalo is where consumers expect to find support, make purchases through ZaloPay, and interact with brands via Official Accounts (OAs) and Mini Apps.

Converge offers native Zalo OA integration at $49/month flat rate for up to 15 agents — one of the few customer support platforms with direct Zalo support, giving businesses a unified inbox for Zalo alongside WhatsApp, Telegram, and eight other channels.

Zalo goes beyond basic messaging. Businesses operate through two complementary channels: Zalo Official Account (OA) Followers enables two-way conversations with customers who have subscribed to the brand, while Zalo Notification Service (ZNS) handles one-way transactional notifications, OTPs, order confirmations, and customer service alerts. Both run on top of a Zalo Cloud Account (ZCA), which requires a Vietnamese legal entity. Layer in ZaloPay for in-conversation payments and Zalo Mini Apps for embedded storefronts, and the platform replaces what Western teams typically split across SMS, email, and a separate help desk.

Vietnamese users treat Zalo the way Western markets treat SMS and email combined: it is the default channel for bank alerts, delivery updates, and government services. While Zendesk and Freshdesk offer third-party Zalo marketplace integrations, these require separate setup and lack the unified-inbox experience of a native connection. Converge connects directly to the Zalo OA API, so messages from Zalo appear alongside WhatsApp, Telegram, Messenger, and other channels in a single queue — no middleware or additional subscriptions required.

Vietnamese customers on Zalo expect prompt, respectful communication with proper Vietnamese etiquette. Use formal address (anh/chị) initially and adjust based on customer preference. Zalo's rich media features — images, documents, stickers, and location sharing — let you create support experiences that feel native rather than corporate.

• Respond in Vietnamese during Vietnamese business hours (GMT+7, typically 8:00–17:30)
• Use Zalo stickers and emoji to create friendly, culturally appropriate interactions
• Share location pins for delivery tracking and service-related support
• Set up your Zalo Official Account with automated greetings, quick replies, and ZNS templates for order confirmations and shipping updates
• Monitor your OA quality grade — Zalo classifies Official Accounts as Good, Medium, or Low based on negative report rate, and re-grades daily; a Low grade caps how many messages you can send until the rolling weekly score recovers
• Plan promotional sends against the ZNS Promotion Quota policy (effective November 2024), which calculates monthly quota from your past ZNS usage rather than granting a fixed allowance
• Connect Zalo OA to your helpdesk so agents handle Zalo conversations alongside other channels without switching tabs
