WhatsApp automation use cases for businesses in Vietnam
A WhatsApp AI agent answers customers in 37 languages (Vietnamese and English among them), sends approved templates for reminders and confirmations, and hands over to your team in a shared inbox. In Vietnam it fits overseas guests, buyers and expatriates best. It does not work on Zalo, and we say so up front.

In practice
How whatsapp automation is used in Vietnam.
- WhatsApp replies run in 37 languages: Vietnamese and English are among them, Mandarin is not.
- Zalo is widely used in Vietnam, and we found no reliable independent figure for how business customers split between Zalo and WhatsApp. Vendor guides describe WhatsApp as used mostly for international contacts; check your own inbox.
- Templates are needed outside the 24-hour window, and Meta reviews them before you can use them.
- A shared inbox lets your team take over any conversation.
Plainly
What this will not do for you in Vietnam.
So you can rule it in or out before you start.
- No Zalo: we do not integrate with Zalo and cannot answer Zalo Official Account messages.
- No Mandarin replies on WhatsApp or chat.
- No catalogue, checkout or WhatsApp Pay messages, and no coexistence with the WhatsApp Business App.
- It does not store proof of consent or check the national do-not-advertise list.
The rules
The rules that apply in Vietnam.
The rules differ by country and change; you are responsible for following them where you operate.
Opt-in and messaging policy
Meta's WhatsApp Business Messaging Policy (last updated 23 September 2026) says you may message only people who gave you their number and opted in, and that you must respect opt-out and block requests. A customer who messages you first has started a conversation; a promotion to past customers needs opt-in. Read the official text; not legal advice.
Advertising messages and personal data
Vietnamese sources read on 25 October 2026 (not the official text) report that Decree 91/2020/ND-CP allows advertising messages only to people who agreed in advance and requires a do-not-advertise list check; a replacement decree is in draft. The Law on Personal Data Protection has applied since 1 January 2026, and summaries say silence is not consent. We support region deployments for enterprise customers. Ask a Vietnamese adviser. Read the official text; not legal advice.
