Do Vietnamese customers use WhatsApp or Zalo more often?

When developing Vietnamese customers, the most confusing thing is often not that there is no contact information, but that after getting the mobile phone number, you don’t know where to go.WhatsApp or Zalo contact. Some people think that WhatsApp should be used for overseas markets, while others think that local people in Vietnam only use Zalo. Both statements are too simplistic.

Zalo is closer to local social networking, life services and communication with acquaintances in Vietnam, while WhatsApp is commonly used in cross-border trade, international cooperation and scenarios with overseas communication needs. The specific platform to choose depends on who the customer is, where the number was obtained, and the channel through which the two parties were originally contacted.

For local consumers in Vietnam,Zalo is usually closer to daily communication

If you are selling local life services, beauty, education, catering, retail or other consumer products,Zalo usually deserves priority.

Many Vietnamese users will passZalo connects with friends, businesses or local helpers. For such customers, Zalo is not a tool specifically used to receive cross-border promotions, but is part of daily communication. The number has been activated on Zalo, which at least indicates that there is a contact portal that is relatively consistent with local customs.

But account opening is still just the basics. Some people have been using it since registration, while others rarely log in; some accounts have complete information, while some accounts have almost no activity. Just confirm the activation status and start sending a large number of messages, but you will still encounter no response to the message.

Local consumer business is more suitable to continue to understand whether the account has been active recently, and then group it based on gender, age, region and product demand. For example, when promoting women's skin care products, gender information may have certain reference value, but you cannot assume that the person will buy it just because she is a woman. The user's city, consumption needs and source of contact information are equally important.

Do cross-border trade,WhatsApp still has practical use cases

If you are contacting exporters, buyers, international logistics practitioners, cross-border sellers or customers who have long-term cooperation with overseas,WhatsApp may make it easier to enter into normal business communication.

Such customers often need to contact partners in other countries and are accustomed to usingWhatsApp handles inquiries, orders, logistics and after-sales. Even if people are in Vietnam, they may not necessarily follow local social habits when choosing communication tools.

For example, a customer submits an inquiry through an independent English website and takes the initiative to leave aWhatsApp number, it will be more natural to continue contacting on WhatsApp later. If the customer comes from a local advertisement in Vietnam and only leaves the mobile phone number in the form and does not select WhatsApp, then sending a WhatsApp message directly may not meet the other party’s expectations.

Platform selection should follow the customer’s original contact path. From which channel do customers enter and which contact method do they actively choose?"What software do Vietnamese generally use?" is more valuable as a reference.

The same Vietnamese number may have been activated on both platforms

You don’t have to choose just one between Zalo and WhatsApp. A Vietnamese user may use Zalo on a daily basis and also use WhatsApp to contact overseas customers.

This type of number has two contact portals at the same time, but it does not mean that both platforms have to send the same content. Repeated contact can easily make users feel like they are being chased for promotion, and may also lead to scattered customer service records.

If the other party is already thereZalo replied that there is no need to send the same message from WhatsApp immediately; if the consultation was initially generated through WhatsApp, priority should be given to continuing the original conversation later. Only when the original channel has not responded for a long time and there is a reasonable basis for contact, should we consider whether to change the platform.

When changing channels, you must also explain your identity and previous contact information. You cannot re-disguise it as the first communication on another platform.

First look at where the customer is coming from, and then decide where to chat.

The suitable contact platforms for Vietnamese numbers from different sources are different.

Vietnam local advertising form

If the ad is in Vietnamese and promotes local goods or services,Zalo is generally more in line with user expectations. It is best to directly let users choose which platform they want to contact through in the form, rather than waiting for the data to enter the customer service list before guessing.

English independent station inquiry

If the user takes the initiative to fill inWhatsApp, indicating that he has accepted this method of communication. Follow-up calls should be prioritized through WhatsApp, and there is no need to force the transfer to Zalo just because the other party is from Vietnam.

Offline activities or store membership

This type of user has a stronger relationship with the local scene and can be arranged based on the contact information selected during registration. When there is no clear choice, it should not be assumed that all mobile phone numbers are suitable for receiving social platform promotions.

Historical order customers

Prioritize checking which platforms have had real conversations in the past. Channels that old customers are already accustomed to using are usually more natural than adding a new contact point.

External customer data

You need to confirm the number source, update time and usage permissions first. Just based on a string of Vietnamese mobile phone numbers, it is impossible to determine whether the owner of the number is willing to receive promotions, and it is also impossible to confirm which platform he often uses.

A group of numbers can be verified on both platforms first.

I already have a Vietnamese customer number, but I don’t know which one to chooseWhen using Zalo or WhatsApp, you can first check the activation status of the two platforms before deciding on subsequent arrangements.

Assume there is3,000 Vietnamese numbers are only used to illustrate the calculation method. After completing the format check and deduplication, the number will be tested for Zalo account opening and WhatsApp account opening respectively.

Four situations may occur after detection:

lOnly openZalo;

lOnly openWhatsApp;

lBoth platforms are open;

lNo account was found on either platform.

What is really useful is not which category has the largest number, but looking at the test results and the source of the numbers together.

If most of the numbers brought by local advertisements are activatedZalo, follow-up forms and customer service portals can pay more attention to Zalo; if English inquiry customers are more concentrated on WhatsApp, it means that this channel has formed clear usage habits; if many numbers are opened on both platforms, it is necessary to use a small-scale communication test to determine where customers are actually more willing to respond.

Digital Planet SupportZalo and WhatsApp account opening tests can be used to complete this basic verification step. When it is necessary to further narrow the scope, filter based on the activity, gender, age or other status actually supported by the platform. The test only answers the account status, and the final selection still depends on the source of the customer and the real reply.

When two platforms send data at the same time, it is easy to see the data clearly.

In order to increase the reply, someone willSend it once via WhatsApp and send it again via Zalo. The customer did not respond and asked separately the next day. What seems like increased reach may actually create new problems.

The same person may be double-counted as two customer leads, and different customer service personnel may take over at the same time.For customers who have been rejected in WhatsApp, if Zalo customer service does not see the record, they will continue to send them. In the end, it is not only impossible to accurately count the response rate, but it is also easy to increase complaints.

The dual-platform list should establish unified customer records based on mobile phone numbers. No matter which platform the user responds to, they will return to the same customer profile, retaining contact time, communication content and rejection status.

If a valid conversation has been formed on one platform, the other platform serves as a backup contact method instead of continuing to send simultaneously.

The judgment standards for local consumption and cross-border business are different

When promoting local beauty, education or store services in Vietnam, focus on the user’s city, age range, consumption needs and whether they are accustomed to passing throughZalo communication. At this time, how far the customer is from the store and whether normal delivery is possible may be more important than whether to use WhatsApp.

Doing foreign trade, international logistics orIn B2B procurement, industry, position, company size and cross-border communication habits are more critical. When customers use WhatsApp, it can only prove that there is an international contact channel, but it cannot directly prove that the other party has the right to make purchasing decisions.

If you are promoting crypto, financial or investment products, you must also consider local regulations, platform restrictions and user risks. You cannot be directly identified as an investment user just because the account is opened.

The same Vietnamese mobile phone number, placed in different businesses, has completely different value judgments. The platform is only the communication portal, and business conditions determine whether the contact is a target customer.

When in doubt, use a small range of response results to judge.

After the platform testing is completed, a small number of customers can be selected for testing without using up all the numbers at once.

When testing, try to keep the customer source and product the same, and only change the contact platform. For example, from the numbers obtained from the same Vietnamese advertisement, select the one with a relatively suitable status.Zalo users and WhatsApp users respectively use short messages in line with platform habits to record actual delivery, reply and clear rejection.

Can't speak Vietnamese at the same timeZalo message, while using completely different English WhatsApp copywriting, and then use the results to determine which platform is better. If the language, content and delivery time are too different, the comparison will be meaningless.

ifZalo has a better response, indicating that the current local business is more suitable to use it as the main entrance; if WhatsApp performs more naturally in foreign trade inquiries, keep WhatsApp; if the responses on both platforms are low, you should check the customer source, product matching and message content instead of continuing to increase the number of sending times.

There is no single answer for Vietnamese customers. Contact local consumers,Zalo tends to be closer to daily usage scenarios; handling cross-border inquiries and international business, WhatsApp still has its own place. First check where the customer comes from, then confirm which platforms the number is subscribed to, and finally choose the main channel with real replies, which is more effective than repeatedly sending messages on two platforms at the same time.
