In private domain marketing,WhatsApp group messaging is considered as one of the efficient ways to initiate customer communication. However, in actual operations, many teams often overlook a key step when performing mass distribution-directory search. In other words, batch sending is carried out directly without verifying number availability, registration status, activity level and other conditions. This approach not only affects the success rate of mass sending, but may also lead to problems such as account restriction, information delivery failure, and resource waste.

Through this article, we will analyze from multiple dimensions:Whether to check the number before mass sending, it will be correctHow much impact does WS have on acquiring customers? What are the specific numbers to be checked? How should this be done?

what is"Directory check"? Why is it a necessary step before mass sending?

"Directory check" is not a technical word, but refers to using professional tools or platforms to check the status of mobile phone numbers to determine whether they meet the conditions for mass messaging. For WhatsApp group messaging, directory tracking mainly involves the following three categories:

lIs itregisteredWhatsApp users

lIs itEmpty number, stop number or incorrectly formatted number

lIs itActive user or online status

Logically speaking, if the message you send does not even exist, or has been logged out or deactivated, of course it cannot be delivered. Once this type of failure rate is too high, it may lead toWhatsApp's risk control system intervenes, which can cause delays in sending, or even cause the account to be disabled.

What are the consequences of ignoring directory enquiry?

Here are common real-life situations for teams:

Abnormally high delivery failure rate

Mass messages were sent without checking the number, and empty numbers, unregistered numbers, and deactivated numbers were mixed in, resulting in a large number of delivery failures, and the system identified them as"Malicious mass posting".

Accounts are frequently restricted or blocked

Continuous operations on invalid numbers can easily trigger the risk control mechanism and affect the account life cycle.

Users are unresponsive and conversion rates are low

Even if the system displays"Sent successfully", but if the target user has been shut down for a long time or is an inactive user, there will be no interaction.

System resources are wasted and efficiency is low

useWhen API or multiple accounts are opened for polling and mass messaging, resources are invested in invalid numbers, resulting in the inability to reach truly high-quality users efficiently.

It can be seen that directory search is not"The icing on the cake" is the underlying guarantee for the success rate of mass distribution.

What specific content should I check before mass sending?

existBefore executing WS group sending, it is recommended to complete the following number detection tasks:

1. WhatsApp registration status

Check whether the target mobile phone number has been registeredA WhatsApp account is the basic condition for successful mass messaging.

2. Empty number identification

Use the access detection platform to determine whether the number actually exists and whether it has been recycled by the operator.

3. Judgment of shutdown/shutdown status

Identify users who are currently unable to receive information to avoid being recognized as abnormal by the system due to too many failed deliveries.

4. Risk number filtering

Eliminate suspected virtual cards and frequently complained numbers to reduce the risk of account triggering.

5. Activity tag identification

Some platforms support identifying whether the number has an avatar, nickname, recent online record, etc., which is helpful for subsequent layered access.

How to complete the directory search action efficiently?

Enterprises can use professional tools to complete batch directory checking tasks. Take the Digital Planet platform as an example:

lSupport uploading mobile phone number list (CSV, TXT format)

lOptional detection content includes: registration status, empty number identification, shutdown status, risk number identification, etc.

lThe system returns test results within a few minutes, with status labels for each number.

lExportable"Registered + normal status" numbers are used for mass sending

This method can save a lot of manual judgment costs and is suitable for routine preparation before daily batch distribution.

How obvious is the increase in mass hit rate?

Taking a certain Middle East market launch team as an example, the number was not checked for the first mass delivery, and the delivery failure rate was as high as42%, the platform account was restricted in the second mission.

After introducing Digital Planet for directory enquiry:

lExcluding empty accounts and unregistered accounts, the proportion32%

lThe delivery failure rate dropped to8.5%

lThe account has been used continuously for more thanNot restricted for 30 days

lThe response rate dropped from less than 10%1% increased to 4.3% and continues to grow

These changes intuitively show that directory search brings not onlyThe "hit rate" is improved, even moreOverall account stability and long-term operational capabilitiesimprovement.

Conclusion

WhatsApp group sending is not a simple message delivery action, but a key link in the systematic customer acquisition chain. Ignoring directory search may seem like a step-saving step, but in fact it will cause irreversible damage to accounts, resources, and user experience.
