2026-01-228 Minute

If you are doing overseas marketing, acquiring customers in private domains, or using WhatsApp, Telegram, or WS to attract customers in batches,

There is a high probability that we have already stepped into these pitfalls: the numbers were imported, but the result was that they could not be sent out;

A lot of money was spent, but few people really responded;

Accounts are also restricted from time to time, making even normal sending a problem.

Many people’s first reaction is:

Is your speaking skills bad?

Is the content not impressing users?

Is the account weight too low?

But after practicing for a long time, you will find that in most cases the problem does not lie in these places, but in the most basic step -Can the number itself be used?.

As long as a large number of empty numbers, unactivated numbers or abnormal numbers are mixed into the data, no matter how good the subsequent marketing actions are, the effect will be severely reduced.

This is why more and more teams going overseas will take a first step before officially launchingWS filter (number filter), clear the unqualified data in advance.

What is WS filtering? Why is it the basic action for overseas marketing?
