in executionDuring the process of sending WhatsApp group tasks, many corporate teams will find such a problem: the sending task is executed normally, but the customer response rate is low, and the system receipt indicates that a large number of messages have not been delivered. After careful analysis, I discovered that the cause was not a problem with the mass messaging system, butThere are a large number of empty numbers and shutdown numbers in the list.

If such numbers are not processed in advance, not only will the success rate of mass sending be low, butWS customer acquisition efficiency will also be seriously damaged.. This article will focus on"How to identify and deal with empty numbers and shutdown numbers", combined with the use of the mass messaging system, provides a set of practical and implementable methods.

What impact will empty accounts and switched-off accounts have on mass messaging?

existIn the WhatsApp system, although group messages support batch sending, its built-in mechanism also has a tolerance limit for the sending failure rate. Once there are a large number of undeliverable numbers in a sending task, the following chain reactions will occur:

lThe account is restricted or temporarily suspended.: The platform identifies it as abnormal transmission and triggers risk control.

lGroup sending task interrupted or failed: The system has a high rate of failed receipts and the task is terminated directly.

lContent distribution efficiency decreases: The probability of effective user reception within the same time period decreases.

lResources are wasted: Invalid numbers consume the limited sending quota and account frequency.

It can be said thatIf empty accounts and closed accounts are not cleared in advance, the consequences will be far more serious than imagined..

How to identify empty numbers and shutdown numbers?

It is obviously unrealistic to rely on manual calls for testing and wait for a failure response. The conventional approach is to use a professional testing platform, such as Digital Planet, to complete the following operations:

1. Batch upload number list

supportCSV/TXT format, you need to include the country code (such as starting with +60) when uploading

2. Check the detection dimensions

Select testKey fields such as "empty number identification", "stop/shutdown status", "registration status", etc.

3. System automatically handles

Detection is completed within minutes and each number returns a clear status label, e.g."Empty account", "Shut down", "Registered", etc.

4. Filter valid numbers

Filter logic to keep onlyUsers with "registered + online + non-empty account" are imported into the group sending system.

This process requires no technical background and can be completed by ordinary operators.

How to use the mass sending system with the cleaning results?

Most bulk messaging systems that support multiple accounts or intelligent scheduling have the function of importing a filtered target number list. Common application methods are as follows:

lAfter testing"Valid number" import sending list

Exclude unreachable users before mass sending to ensure the success rate of sending.

lConfigure the secondary sending mechanism

For the statusFor users who are "shut down", set a delayed task or send it twice in a specified time period to avoid interruption at the wrong time.

lStatistics of sending success rate after cleaning

The bulk sending platform usually reports that the sending was successful./Failure details, conduct retrospective analysis with the cleaning results, and continuously optimize the next batch of delivery strategies.

This kind ofThe closed-loop mechanism of "cleaning → mass sending → recycling → screening" can effectively improve the efficiency of WS customer acquisition.

How do different industries use empty number filtering strategies?

Cross-border e-commerce seller

After filtering out empty numbers, logistics reminders and discount promotions will be sent to reduce complaints and improve customer experience.

finance/education services

Avoid dialing empty numbers by mistake and ensure that service notifications and reminders can truly reach valid users.

Overseas agent operator

Use cleaning+The group sending combination provides customers with automated operation services, saving labor and significantly reducing the failure rate.

After-sales service team

After clearing the numbers of customers who have made transactions, we will uniformly send follow-up content in bulk and build a customer satisfaction management mechanism.

Practical advice: How to keep your number library available?

lA number check is performed before each group sending., maintain list quality.

lEmpty number detection andWhatsApp registration detection is performed simultaneously, to reduce repeated operations.

lRegularly retest old customer datato avoid sending to changed or deactivated numbers.

lUsing mass messaging tools"Send in batches" function, perform strategic processing on numbers with different detection statuses.

lMonitor delivery receipt data, once the failure rate is abnormal, immediately check whether any invalid numbers are missing.

Summarize

want toWhatsApp group messaging can be made more stable, more accurate, and more cost-effective. The first task is not to study the vocabulary, but toImprove number availability. The information is only meaningful if the number is available.

The identification of empty numbers and shutdown numbers through detection tools, combined with the implementation of group messaging system policies, not only improvesThe efficiency of WS customer acquisition also protects the security of account sending.
