In Southeast Asian markets,Zalo is a local instant messaging application that is highly used by Vietnamese users. Many brands and cross-border merchants have taken the potential of this platform and hope to achieve accurate access through the Zalo mass sending function. But do you know?If no empty number cleaning and account status recognition are performed before mass sending, most of the budget may be wasted, and may even trigger the platform's risk control.

So let’s talk about this article:existWhat preparations should be made before Zalo mass broadcasting to truly improve hit rate and conversion effect?

WhyDo Zalo must be screened before mass dispatch?

Don't underestimateThe two words "empty number". In Zalo mass, "empty numbers" don't just refer to thoseNot registeredZalo's number, also including:

lNumber is logged out but not updated

lZalo account has been blocked or has not been logged in for a long time

lRegistered but never active"Zombie"

These accounts will not only not respond to any response during your mass sending process, but may also frequently send invalid information, resulting in your account being recognized by the system as"Spam Source".

More importantly:The more empty numbers, the higher your sending cost, and the deliveryThe lower the ROI.

How to judgeIs the Zalo account empty?

If you are manually uploading a bunch of Vietnamese mobile phone numbers to do group sending, I'm sorry, you can't tell which ones are empty numbers just by your naked eyes.

At this time, you need to use a professional platform to help you complete the following tests:

lRegisteredZalo: Determine whether this mobile phone number is actually openedZalo account.

lIs it currently active: Check whether the account has active behaviors such as recent login, message interaction, avatar update, etc.

lAccount status: Some accounts may be registered, but they are in a state of ban, freeze, cancellation, etc.

lInteraction frequency tags: Some platforms can also tell you whether the account is"Habitually neglected" strange news.

In the Digital Planet Platform, we provideZalo detection tool supports batch import of tens of thousands of numbers at one time.Complete the removal of empty and invalid accounts within a few minutes, and can export result tables, which facilitates subsequent screening and mass sending.

What other account characteristics should be detected before mass sending?

In addition to whether it is an empty number and whether it is active, it is also recommended to filter the target account in the following dimensions before mass sending:

Age and Gender

Especially in e-commerce, life services and other industries, the response preferences of users of different ages vary greatly. For example:

lUsers aged 18-24 are more likely to accept promotional information

lUsers over 30 years old pay more attention to brand services and practical value

Through the tag detection function of Digital Planet, you can quickly identify the gender and age of each account.Make the crowd targeting more detailed.

Language and Regional Labels

If you are facing customers across Vietnam, please pay attention to:

lNorthern users mostly use standard Vietnamese language, prefer formal communication

lSouthern users have a more colloquial language and are more responsive to relaxed speech

Through regional tags, you can adjust your tone appropriately in group speech to improve your response rate.

How to group after the empty number detection is completed?

FinishAfter the Zalo empty number detection, the most critical step isReasonably group and place in segments, prevent excessive mass sending and causing account traffic restrictions.

It is recommended to do this:

lGroup1: Active users+ Age adaptation + Recent interactive behavior → Main products

lGroup2: Activated but low active users → Gentle guided speech

lGroup3:close30 days of unactive account → Delayed reach or cold start account maintenance strategy

After the detection results are exported, the Digital Planet Platform will automatically label and generate grouping according to the conditions.Significantly improve mass hit rate and user experience.

What are the consequences of not conducting short-shot detection?

Don't be lucky. If you skip the step of cleaning up the empty number, these problems may occur:

lMassive large number of unregistered users → No response to delivery

lThe failure rate of account sending in a short time is too high → The Zalo system judged as garbage marketing

lThe proportion of inactive users is too high → The data cannot be evaluated for delivery
