doingAnyone who works in Zalo marketing knows that mass messaging is one of the most commonly used and most effective methods of reaching people. However, there are not many companies that truly make mass distribution efficient and accurate. Why?Most people make a fatal mistake at the beginning: not cleaning up empty numbers.

Many merchants upload tens of thousands of Vietnamese mobile phone numbers and start mass sending. It seems that the volume is large and the coverage is wide, but in fact there is only a handful of responses. In the final analysis, the problem is not the copywriting or the timing, but that you simply did not communicate with"Real users" speak.

Today, we will sort out a clear and enforceableZalo empty account detection full process guide, tell you how to screen out real users, eliminate invalid numbers, and improve the hit rate before mass sending.

Why is it right to clean up empty numbers?Is Zalo mass sending so important?

Zalo is one of the mainstream communication tools in Vietnam, but this does not mean that the Vietnamese mobile phone number you have must be activated by Zalo.

Moreover, even if you registerZalo, may also be:

lNot logged in for a long time"Zombie Number"

lThe account is frozen, banned, or canceled

lDead account that has never been interacted with

If you send a mass message without checking in advance, these numbers will not only not respond to you, but will also have chain consequences:

lThe failure rate of sending increases and accounts are easily restricted.

lMarketing conversion rate is dragged down by empty accounts, and data cannot be analyzed

lThe cost is wasted, the effect is“It looks like it’s done, but it actually doesn’t work.”
