DoingEveryone in Zalo marketing knows that mass messages are one of the most commonly used and effective ways to reach them. But there are not many companies that truly make mass publishing efficient and accurate. Why?Most people make a fatal mistake at the beginning: not clearing the empty numbers.

Many merchants upload tens of thousands of Vietnamese mobile phone numbers and start sending them in groups. It seems that the volume is large and the coverage is wide, but in fact there are few responses. In the final analysis, the problem is not the copywriting, not the timing, but you are not at all"Real user" speaks.

Today, let's sort out a clear and executableZalo Air Number Detection Full Process Guide, tell you how to filter out real users, remove invalid numbers, and improve hit rate before mass sending.

Why is the empty number cleaned?Is Zalo mass stylist 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 in your hand must be enabled.

And even if you registerZalo, it may also be:

lHaven't logged in for a long time"Zombie"

lAccount is frozen, banned, and cancelled

lDead numbers never interacted

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

lThe sending failure rate increases, and the account is easily restricted

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

lCost is spent, effect"It looks like it's done, but it's actually invalid"
