Under the wave of global marketing, many companies have set their target marketsUSAandIndia, the mobile phone user base in these two countries is huge and the communication infrastructure is complete, which is a popular choice for cross-border promotion. But the problem follows:A large number of invalid numbers are mixed into the list, resulting in extremely low marketing reach rate and even severely banned accounts.
Is there a wayIs it possible to identify empty numbers, shutdown numbers, and real active numbers before delivery? I have personally tested the results in several ways, and this article will talk about:How to determine whether the numbers of the United States and India are available resources.
Phase 1: I initially depended on itTo judge "format", the result is very wrong
At the beginning, I also took a detour and saw that the number format was"Beginning with +1" or "Beginning with +91", if the length is correct, the default is the valid number.
But reality slapped in the face:
Even if it isA large number of "standard format" has beenShut down, log out, or even have not registered a social account.
There are still a lot of existence in the United StatesGoogle Voice virtual account looks like a real account, but in fact no one uses it at all.
India is even more exaggerated, some numbers are specially registeredWhat was deprecated after the app was completely a "zombie account".
Therefore, relying solely on format judgment is basically equivalent to blind vote.
Phase 2: Manual dialing+Manual verification, but too low efficiency
I've tried dialing manually:
lAfter dialing, record as"Active Number"
lCan't play, voice prompt"Unallocated" and "Shutdown", record as empty or shutdown number
Although this method is the most original and accurate, the problem is:
lToo low efficiency,1000 numbers take at least one day
lFew labor and phone bills, and it is easy to trigger user complaints
lUnrecognizedWhatsApp/Telegram activation status
This method is only suitable for small batch verification, not for everyFilter overseas numbers at level 100,000.
Stage 3: Verification with social platforms is easy to be mistakenly blocked
I used it for a whileWhatsApp API script automatically detects whether the number is registered with WhatsApp. It can indeed identify some number status, but the platform's risk control is becoming more and more stringent:
lIf the trigger frequency is high,Block the inspection account
lIt is impossible to determine whether the number is down, only"Whether it is activated"
Many times, the number has been detected and registeredWhatsApp, but the user is not active at all, which is equivalent toPseudo-active number
And this detection method is prone to violationWhatsApp's usage specifications are not suitable for commercial scenarios.
Stage 4: I switched to the digital planet system, and the results were much more stable
After trying various methods, I finally chose a professional air number detection platform——Digital Planet, its advantages are:
lSupport the United States+1 and India +91 two major countries
lCan identify at the same timeNo, shutdown, active status, blocked status
lThe detection results are exported according to status, which facilitates the connection between subsequent delivery systems
lNeed notAPI, no account blocking, just upload and import the web page
My actual test100,000 U.S. numbers, the original data has a hollow rate of up to41.7%.
After screening,The WhatsApp mass sending system no longer has batch refunds or risk control problems.
In the Indian market, filter out the valid number and place itThe ROI has increased by 63%, and the conversion rate after customer service has actively contacted has also increased significantly.
These dimensions are what I pay most attention to, and they can be detected by digital planets.
If you want to determine whether a number can be delivered, you must pay attention to this information:
lCurrent status of the number: Whether the number is empty, whether the machine is shut down, whether it is closed
lSocial platform activation status: Whether it is supportedWhatsApp, Telegram, LINE, etc.
lAccount activity: Is it online recently? Is it a zombie account?
lRegistration source judgment: Whether it is a virtual number, whether it is a temporary registration purpose
lNumber format verification: Whether it is a standard structure, whether there are extra characters
Once these data are screened out, it will not only improve your marketing efficiency, but also save a lot of SMS costs.API call costs and manual verification costs.
One thing you may overlook: downtime numbers and empty numbers are not the same thing
Many friends will ask:"Aren't both shutdown numbers and empty numbers unavailable?"
Actually not exactly the same:
lShutdown numberIt has been registered but has temporarily arrears or has suspended its use. Some platforms such asWhatsApp may also find the account traces, but the interaction rate is extremely low
lEmpty numberIf the number is completely cancelled or the number is not allocated, the message will definitely fail.
In high-precision delivery scenarios,Priority is given to the empty number, and then evaluation is made to be used for the shutdown number, is a more rational screening logic.
It is recommended to use digital planets to run the detection process
After my personal test, the most labor-saving method for filtering numbers in the US and Indian markets is to use them directly.Digital planet's air number detection system:
lNo need to download the client, just use the web page
lsupportExcel, TXT import and export
lFast detection speed,100,000 numbers only take a few hours
lProvide detailed status fields for each number, which are convenient for subsequent classification
Especially doingTeams that include WhatsApp, SMS, social advertising, and overseas customer acquisition must do this before sending.
If you don’t sifte numbers, it’s equivalent to burning money; if you sifte numbers in the wrong numbers, it’s equivalent to sending death.
