In cross-border marketing, whether you are doing SMS,WhatsApp, outbound calls, e-commerce private domain or CRM reconnection, there is one action that is often overlooked, but directly determines the reach effect——Directory check.

Many teams have invested a lot of budget, but suffer from low delivery rates, poor response rates, and easy account throttling. The reasons are often not complicated:The list is full of empty numbers, out of service numbers, and unregistered numbers.

If you don’t do empty account cleaning, your marketing actions will be done from the first step."Half-waste". This article will explain from a practical perspective why directory verification is necessary before cross-border marketing, and how to use Digital Planet to automate and batch this step.

Why is cross-border marketing necessary to check the number?

Uncontrollable factors for cross-border numbers are far more complex than domestic ones. The most common ones include:

lLocal operators frequently recycle numbers

lThe proportion of virtual numbers is high (especially in Southeast Asia, the Middle East, and Latin America)

lTransnational users change their numbers much more frequently than in local markets

lPlatform registration failed, number format is not standard

These situations will render your send action invalid.

If you don’t check the number, you will encounter:

lSMS bounces soar

lWhatsApp group sending failure rate exceeds standard

lOutbound call completion rate is extremely low

lThe account was determined to be abnormally sent by the system.

lDelivery costs continue to be wasted

For cross-border marketing, directory inquiry is not optional;Just needed.

Why does an empty number affect the delivery rate?

Cross-border number distribution is complex, and each country’s operator logic is also different. The following three types of numbers have the greatest impact on reach:

Empty number: Logged out or never enabled

Outage number: Unable to receive text messages or access social applications

Unregistered number: Unable to receiveWhatsApp/Telegram messages

If the proportion of empty numbers in the sending list is too high, the result will be:

lThe platform is identified as"Frequently sending invalid numbers" triggers risk control

lThe mass sending system frequently fails and interrupts tasks.

lHigh-cost text messages are wasted

lThe outbound call agent's line is busy but I can't get through to anyone.

lThe life cycle of WA number is shortened, and it is easy to be disconnected and blocked.

Your delivery rate will be directly dragged down by empty numbers.

How to check the number? What is the most time-saving method for cross-border teams?

The most common and effective way is to use a global testing platformBatch directory inquiry.

by digital planet For example, cross-border teams can use it to:

lGlobal empty number detection

lIdentification of shutdown status

lIs WhatsApp registered?

lNumber availability judgment (reachable/unreachable)

lRisk number segment identification (virtual card, abnormal number segment)

The steps are very simple:

Step 1: Upload the number file (TXT/CSV)

Support global country codes, such as+60, +1, +44, +91, etc.

Step 2: Select detection dimensions

Empty account identification, outage detection, and social registration status detection can all be checked at once.

Step 3: Wait for system processing

Ten-thousand-level detection can be completed in a few minutes without manual verification.

Step 4: Export the filtered valid numbers

The file will beLabels such as "real number/empty number/downtime/unregistered" are displayed, and real numbers are used to send directly.

Digital Planet is specially designed for cross-border scenarios, covering global operators, and is suitable for high-frequency scenarios of cross-border teams.

How significantly does directory inquiry improve delivery rates?

The following are real common case types:

A Southeast Asian e-commerce team

SMS delivery rate before number check58% → increased to 91% after directory search

A cross-border service provider doesWhatsApp group messaging

Failure rate before cleaning40% → reduced to 7% after cleaning

An outbound agent team makes hundreds of invalid calls every day

Save by using Directory CheckMore than 30% of agent labor time

A certain traffic running team

Due to the high failure rate, the account is restricted and the account life cycle is extended after the number is checked.3–5 times

These data illustrate:

The delivery rate of cross-border marketing is almost entirely determined by number quality.

Best Practices for Directory Enquiry in Cross-Border Marketing

To avoid wasting budget, cross-border teams usually follow:

lCheck the number before each delivery

lSMS, outbound calls,WhatsApp will use the same cleaned data

lEstablish"Real number pool", regular review

lStatus label importCRM to avoid secondary confusion

lDirectory inquiry and mass messaging tools can be used simultaneously to form a complete link.

Digital Planet can stably support these processes and make directory search an executable and scalable fixed action.

Conclusion

The reach cost of cross-border marketing is getting higher and higher, and the reach logic is becoming more and more strict. There is actually only one link that you can really control:

Make sure the sending number itself is valid.

Directory checking may seem simple, but it can directly improve delivery rates, protect accounts, and save costs. It is an action that cross-border teams should not skip.
