Zalo Official Account Marketing in Vietnam: Setup, Ads and ZNS

Why does this matter? In Vietnam, many customers would rather message a business on Zalo than fill in a form or send an email. If your brand is not on Zalo, leads go cold, follow-ups get missed, and competitors who reply in minutes win the sale. This guide explains how Zalo Official Account marketing works and how to set it up without wasting time or budget.

Key Takeaways

• Zalo is a daily habit in Vietnam, with VNG reporting tens of millions of monthly users, so an Official Account is often the main way customers contact a business.
• A Zalo Official Account must be verified, and as of 2026 Zalo offers a free Basic tier plus paid packages that unlock more messaging, team seats and automation.
• ZNS (now sold under Zalo's business message products) lets you send approved template messages, like order confirmations, to customers' phone numbers from about 200 VND per message.
• Zalo Ads can grow followers, collect leads and push people into chat with your OA.
• Vietnam's personal data rules tightened, with a dedicated Personal Data Protection Law in effect from January 1, 2026, so get clear consent for marketing.
• Native Vietnamese writing and fast replies matter more than fancy design.

What Is a Zalo Official Account?

A Zalo Official Account, or OA, is a business profile inside Zalo. Think of it as a mix of a Facebook Page, a WhatsApp Business account and a mini website. Customers can follow your OA, message you, read your articles, see your products and get notifications.

Unlike a personal Zalo account, an OA is built for business. You can add team members, use chat tools, connect a chatbot, link to your CRM through an API and track performance. Zalo also offers Mini Apps, which are small apps that run inside Zalo, for booking, loyalty programs or shopping.

Why Zalo matters more than you think

Many foreign brands focus only on Facebook and TikTok in Vietnam. Those platforms are important for reach, but Zalo is where conversations and repeat business often happen. Customers save your OA, ask questions before buying, get delivery updates and come back to reorder. For services like clinics, schools, real estate, travel, restaurants and retail, Zalo is often the main sales channel.

How to Set Up and Verify Your Zalo Official Account

Setup is not hard, but the details matter. Here is the process we follow.

1. Create the OA from a Zalo account. Use an account owned by the business, not a staff member's personal phone, so you do not lose access if someone leaves.
2. Choose your category and name. Pick a name that matches your brand and the category that fits your business.
3. Prepare verification documents. Zalo requires verification for business OAs. Expect to provide business registration documents and proof that you have the right to use the brand name.
4. Complete your profile. Add a logo, cover image, short description in Vietnamese, address, hotline and website.
5. Set up the welcome message and menu. The menu sits at the bottom of the chat and can link to products, booking, FAQs or a hotline.
6. Add team members and set who can reply to chats.
7. Link a Zalo Business Solutions account if you plan to buy a package, run ZNS or use ads. Zalo says paid packages require a verified OA linked to a prepaid business account.

A note for foreign brands

Verification usually works most smoothly with Vietnamese business documents. Brands without a Vietnamese company often run their OA through a local distributor, agency or partner company. Before you do that, make sure your trademark is protected in Vietnam, so the account and brand stay under your control. Our guide on registering a trademark in Vietnam explains how. Requirements can change, so check Zalo's current verification rules as of late 2026.

Zalo OA Packages and Costs in 2026

As of late 2026, Zalo's pricing page lists four service packages for verified Official Accounts. Prices below exclude VAT and may change, so confirm them on Zalo's official site before you budget.

• Basic (Cơ bản): Free. Basic chat tools and customer information management.
• Standard (Tiêu chuẩn): Listed at 1,000,000 VND per year. Adds better chat tools, up to 5 team members, and 500 consultation messages per month outside the 48-hour reply window.
• Growth (Tăng trưởng): Listed at 1,400,000 VND for 6 months or 2,500,000 VND per year. Adds chatbot and automation features, API access, up to 15 team members and 2,000 consultation messages per month.
• Comprehensive (Toàn diện): Listed at 3,400,000 VND for 6 months or 6,000,000 VND per year. Adds the highest limits, more team seats and priority support.

What the 48-hour window means

Zalo's packages refer to messages sent outside a 48-hour window. In plain terms, you can reply freely for a period after a customer messages you. After that window closes, follow-up messages count against your package limits. This is why fast replies matter. If you answer within the window, you avoid extra costs and close more sales.

For most small and mid-size brands, the Growth package is a good starting point because it includes automation and API access. That lets you connect a chatbot or your CRM so leads are answered around the clock.

ZNS: Zalo Notification Service Explained

ZNS lets a business send template messages to a customer's phone number on Zalo, even if they have not followed your OA. Zalo now markets this under its Business Message products. Common uses include order confirmations, delivery updates, appointment reminders, one-time passcodes, payment requests and vouchers.

How ZNS works

1. You need a verified OA.
2. You create message templates, such as "Your order has been confirmed."
3. Zalo reviews and approves each template before you can use it.
4. Your system sends messages through the API, or through a partner platform, using the customer's phone number.
5. If the customer replies, the conversation continues in your OA chat.

ZNS costs as of 2026

Zalo's business message pricing page lists most template types from 200 VND per successfully sent message, and authentication, payment request and voucher templates at 300 VND. The first action button is free and each extra button adds 100 VND. Prices exclude VAT, and Zalo notes some industries get special rates. Always check the latest price list before you plan a big campaign.

ZNS tips

• Use ZNS for useful messages, like confirmations and reminders, not spam. Templates that look like pure advertising may be rejected.
• Keep messages short, with one clear button.
• Make sure you have the customer's consent to contact them, and that you collected their phone number legally.

Zalo Ads: Growing Your Audience

An OA with no followers is an empty shop. Zalo Ads helps you get people in the door. Zalo's ad platform offers formats that can grow OA followers, collect leads with forms, promote articles and products, and start conversations with your OA.

How to use Zalo Ads well

1. Start with a clear offer. A discount, free consultation, sample or useful guide gives people a reason to follow or message you.
2. Target by location and interest. Zalo is strong for local targeting, which works well for stores, clinics and service businesses in cities like Ho Chi Minh City, Hanoi and Da Nang.
3. Send ads to chat. Ads that open a conversation with your OA often convert better than ads that send people to a slow website.
4. Write in natural Vietnamese. Machine-translated ads feel strange and hurt trust. We use native Vietnamese writers for every ad.
5. Test small first. Run a few versions with a small budget, then move money to the best performer.

You can also grow your OA for free. Add a Zalo button to your website, put a QR code on packaging, receipts and store counters, and mention your OA in Facebook and TikTok content.

Zalo Official Account Marketing Playbook: Content and Chat

Once people follow you, the real Zalo Official Account marketing work begins. Your goal is to be helpful, not noisy.

What to send

• Welcome message: Thank new followers and offer a small welcome gift.
• Useful articles: How-to tips, product guides and seasonal advice.
• Promotions: Limited offers around Tết, mid-year sales, 9.9, 11.11 and 12.12.
• Service updates: Opening hours, new branches, new products.
• Loyalty messages: Points, birthday offers and reorder reminders.

Do not blast promotions every day. Followers can block you, and too many messages hurt your reputation.

A simple chat script

Here is a basic flow you can adapt for a first-time inquiry, written in English for clarity. Your team or chatbot would use natural Vietnamese.

1. Greet: "Hello, thank you for contacting us. How can we help you today?"
2. Qualify: "Which product are you interested in? Is this for you or as a gift?"
3. Recommend: Share one or two options with prices and a photo.
4. Answer concerns: Delivery time, payment methods, warranty or returns.
5. Close: "Would you like us to reserve this for you? We can confirm your order now."
6. Follow up: Send a ZNS order confirmation and a delivery update.

Using AI to reply faster

Speed wins on Zalo. A chatbot connected to your OA can answer common questions instantly, collect contact details and pass hot leads to a human. Our AI implementation service sets up multilingual AI employees for Zalo, LINE, WhatsApp and WeChat, so your customers get answers in Vietnamese even when your team is asleep. If you also sell in Indonesia, our guide to WhatsApp marketing in Indonesia shows how the same approach works on WhatsApp.

Data Privacy and Advertising Rules

This is general information, not legal advice. Rules change, so confirm with a Vietnamese lawyer as of late 2026.

Vietnam has tightened its personal data rules. Decree 13 from 2023 set out early requirements, and a dedicated Personal Data Protection Law took effect on January 1, 2026. In practice, this means:

• Get clear consent before using personal data for marketing.
• Tell people what you collect and why.
• Let people opt out or ask you to delete their data.
• Do not buy phone number lists for ZNS or ads.
• Keep customer data secure and limit who can access it.

Vietnam also has advertising rules, including stricter controls on health products, cosmetics, food supplements and financial services. Some products need approval of ad content before you run ads. Check with a local adviser before promoting regulated products.

Common Mistakes to Avoid

• Setting up the OA under a staff member's personal account. You can lose access when they leave.
• Skipping verification. Unverified accounts look less trustworthy and cannot use key features.
• Slow replies. Missing the reply window costs you sales and message credits.
• Using machine translation. Vietnamese customers notice instantly.
• Spamming followers. Too many promos lead to blocks.
• Ignoring data consent. Privacy rules now carry real risk.
