Before sending bulk SMS overseas, a core question that cannot be avoided is:Can these numbers receive text messages?
Many users often encounter this problem: there is no error reported by the sending system, but there is no response after delivery, or the failure rate is as high as more than half. Not only the SMS fee is wasted, but the platform may alsoRisk control is triggered by "abnormal delivery ratio". In the final analysis, it is becauseIs the number truly reachable?, was not effectively verified by the system before sending.
This article will focus onThe common question "How to judge whether an overseas number is reachable" is expanded upon, and the principles, advantages and disadvantages of various detection methods are analyzed in depth, and how to useGlobal Number Detection by Digital PlanetAPI interface, complete efficient screening before mass messaging, improve hit rate, reduce failure rate, and optimize cost structure.
1. Why must the number reachability be determined before sending a text message?
Domestically, operator resources are relatively concentrated, and SMS arrival rate fluctuations are controllable; however, overseas, it is subject toDifferences in number formats, regional operator channels, virtual number frequencies, banning mechanisms, and time zone restrictionsWhether a text message can be delivered or not is highly dependent on the quality of the number.
Common questions include:
lThere are a large number of unregistered or unregistered numbers in the imported numbers.
lThere are format errors and falsely generated number segments.
lThere is a special virtual operator number that cannot be routed
lThere are users whose accounts have been blocked and who have been blacklisted through SMS channels.
lThe number exists, but is inactive or has no reception capability
Once these problems are not identified in advance, the SMS failure rate will increase significantly, resulting inBudget waste+ Conversion rate drops + Platform restrictionsWait for the chain reaction.
2. How to determine whether the number is"Accessible"? These 5 methods are common but vary greatly
1. Reverse judgment based on the result of sending text messages (judgment after the fact)
The most common way is: send in bulk first, and then based on the receipt information (such as successful/failure status) to infer whether the number is valid.
shortcoming:
lbelong"Post-processing", the cost has already been incurred
lMany platforms have ambiguous failure status returns (e.g.Unknown, Null)
lDifficult to batch process and determine attribution
2. Use the operator's basic query interface (authorization required)
some countriesLocal operators in the / area support querying number status through the interface, including network status, whether it is down, etc.
shortcoming:
lNot universally available and only available in a small number of markets
lHigh authorization cost, slow interface response,The API interface is highly closed
lThe accuracy of identification of virtual operators or cross-network number segments cannot be guaranteed.
3. Use the “pre-verification” function of the third-party SMS sending platform
Some platforms provide a number format verification function before sending, and mark the risk level (high probability of failure, unknown rank, etc.).
shortcoming:
lMost judgments are based on static rules and cannot identify whether the number has been blocked./Recycle
lUnable to identify dynamic status such as account ban, deactivation, etc.
lDoes not support social platform behavior label judgment (such asWhether WhatsApp is registered)
4. Social status linkage judgment (indirect inference)
For example: Check whether a number is registeredWhatsApp, determine whether it is active and recently online through the WhatsApp status detection API interface. Those who register social accounts generally also have the ability to receive text messages.
advantage:
lIt can reflect the authenticity and usage activity of the number.
lSuitable for priority delivery screening in marketing scenarios
Limitations:
lIt cannot completely replace communication channel detection and is only used as a reference.
lNot all countriesWhatsApp coverage is high, and adaptation strategies need to be adjusted
5. Use the Digital Planet global number detection API interface (recommended)
Global number detection provided by Digital PlanetAPI interfaceIt is a service specially designed for pre-delivery detection of text messages. It uses structured algorithms to+Real-time response mechanism to conduct the following multi-dimensional screening of numbers:
lIs it a real number that has been activated?
lIs it a local carrier routable number?
lWhether it has been banned, blocked, deactivated or recycled
lWhether it is a duplicate number, invalid prefix, or illegal area code
lWhether it supports receiving text messages and the channel status is normal
lHave you registered with mainstream social platforms (such asWhatsApp registration status detection API interface, Telegram detection interface)
Detection results output structured tags,like:
lReachable:√
lReachable but suspected to be a false number:√ (medium risk)
lNot reachable:×
lFormat error:×
lUnknown rank/High risk of failure: ×
3. How much difference can there be in the effective hit rate before and after using global number detection?
In the practical feedback from a large number of overseas users, the number detected by Digital Planet,SMS delivery hit rate increased on average30%-60%. Mainly reflected in:
lSMS arrival rate increases: Avoid sending to blocked, empty, or wrong number segments
lImproved user response rate: The reserved number has real usage behavior
lFailure rate decreases: The SMS platform will not limit the speed or block sending due to continuous failures.
lSMS costs are more controllable: Really realized“Only send text messages to people who may see them.”
4. How to access the detection process before sending bulk SMS? The recommended steps are as follows:
1.Before importing numbers, use the detection interface to clean the data.
Upload the list of target numbers to the Digital Planet platform, or viaAutomatically identify and mark the status after API docking.
2.Set tag filter rules
It is recommended to keep onlyNumbers with "normal status/reachable/standard format" are used as the final sending pool, and the others are set to observation or delayed delivery.
3.Combined with social status detection to enhance quality assessment
such as combiningWhatsApp status detection API interface and Telegram account activity detection API further identify the social activity of the number and increase the probability of interactive response.
4.Import the SMS platform and standardize the format before sending.
Make sure to import to international standardsE.164 format to avoid system mistransmission or recognition failure due to format errors.
Conclusion: Whether a text message can be sent or not depends on the quality of the data.
The success of overseas bulk SMS does not depend on whether the SMS platform is stable, but whether your number is properly cleaned. Number accessibility is the first screening before all launches.
By using Digital Planet’sGlobal number detectionAPI interface, you can complete format checking, status identification, social comparison and behavioral assessment before sending in batches to truly establishAn SMS user pool that is “reachable, responsive and convertible”.
Instead of waiting for failed data to be reported, it is better to eliminate invalid numbers before posting. Try the number detection service now to improve your SMS hit rate from the source.
