Steps that must be completed before sending cross-border text messages: Detailed explanation of international number validity verification method

When doing cross-border SMS delivery, many teams will focus on channel prices, sending frequency, and copywriting conversion, but ignore the prerequisites for successful delivery:Whether the target number is real and valid and whether it can receive international text messages.

You may have used a high-quality SMS service provider, and the content design is very attractive, but if the number itself has been cancelled, the format is abnormal, and the operator does not support international SMS reception, then this SMS is equivalent to"Grey hair".

Conducted before sending international SMS messagesNumber validity verification, not only can significantly improve the delivery rate, but also reduce delivery costs, avoid channel restrictions, and improve the overall conversion rate of return. This article will systematically analyze how to complete the validity verification of international numbers and introduce how to useDigital Planet PlatformComplete this step efficiently.

1. The SMS failure rate is high, which is often not a platform problem.

Have you ever experienced:

lBulk sending receipt display"Sent successfully", but customer feedback "Did not receive text message"?

lThere are almost no clicks or interactions after the launch, and the data is like nothing?

lThe same channel, sent to different countries, the effect is very different?

lAfter sending a large batch, the account was speed-limited and the channel was blocked?

Ultimately, the problem is often not the platform or the copy;The number you sent is itself"unreachable". Common question types include:

lEmpty number, canceled number

lVirtual number segment, temporary number segment

lFormat error, no country code

lBlocked by the operator and refused to receive international text messages

lArea code does not match channel policy

Without verifying these issues in advance, text messages will become more and more unsuccessful.

2. What should be done to verify the validity of the number before sending the SMS?

A qualified international SMS pre-verification work should cover the following key dimensions:

1. Format standardization detection

Eliminate data that does not comply with international number specifications, such as missing country area codes, abnormal number lengths, garbled fields, etc.

2. Is it a real number?

Identifies whether the number is in a valid registration status to avoid sending text messages to"Empty number" or unallocated number segment.

3. Whether it is possible to receive text messages

Verify whether the number has been blocked, in arrears, restricted from receiving text messages while roaming, or actively blocked by the user.

4. Whether it belongs to virtual or VoIP segment

Such numbers may bypass operator audits, and some SMS channels will be blocked by default.

5. Is it an operator in the target country?

Cross-border sending must ensure that the number ownership is consistent with the channel policy to avoidStrong interception caused by "the channel is thrown to the wrong country".

5. How to use the test results after the verification is completed?

The value of filtering results is not only to exclude invalid numbers, but also to help you build a more stable delivery system:

lImport SMS platform: Select only"Exist + receivable" numbers are imported into the SMS platform to improve the delivery rate

lBuild user tag pool: Create a label for the number, such as"Risk number segment", "cold start number", "registered to receive", etc.

lImprove channel score: Avoid account restrictions due to high failure rates and ensure long-term delivery stability

lGroup sending in layers: Users in different statuses set different delivery rhythms and content to improve click-through rates and conversion rates.

lfor subsequent analysis: Combine conversion behavior and number status to analyze user value and optimize content strategy

The first step to successful cross-border text messaging is to make sure the number you send can"receive".
