Precisely screen the voice group call list and eliminate abnormal numbers to ensure the stability of the advertising system

In voice group calling and automatic outbound calling scenarios, the stability of the advertising system and dialing system increasingly depends on data quality. When many companies expand the scale of voice marketing, they often focus on dial-up speed, line concurrency,AI speech optimization has ignored a more basic issue:Whether the list itself is healthy and whether there are a large number of abnormal numbers.

The existence of abnormal numbers will not only lower the connection rate, but may also cause chain reactions such as abnormal system recognition, line restrictions, and increased complaint rates. Once an ad account or voice line is flagged, the recovery costs are much higher than the upfront screening costs.

Therefore, conducting a comprehensive data screening before a formal group call has become a standard action in the voice marketing industry.

Why do abnormal numbers affect system stability?

In actual voice group calling projects, abnormal numbers usually include the following categories:

lLong-term downtime or empty number

lVirtual number, network number segment

lHigh frequency complaint history number

lHigh-risk number segments that have been restricted by operators

lMobile phone number with wrong format or unknown location

lAccounts registered in batches but with no real usage behavior

When these numbers enter the outbound call system, possible consequences include:

lThe call failure rate increases and system resources are occupied.

lRepeated dialing of the same batch of abnormal numbers triggers line risk control

lThe rate of complaints has increased, affecting the health of advertising accounts.

lCall concurrency efficiency decreases, affecting the overallROI

lDistortion of data feedback, misjudgment of words or product effects

From a system perspective, the exception number is not only"Invalid" is even more "risky".

How does Digital Planet help companies eliminate abnormal numbers?

Digital Planet focuses on global number status identification and risk screening, coveringProvides systematic screening capabilities for voice group call scenarios in 244 countries and regions.

Registration status identification

Determine whether the mobile phone number is a real registered user, and filter out unregistered or unused numbers.

Exceptions and ban marks

Identify numbers with complaint history, high-risk behavior, and abnormal login tracks, and automatically label them with risk.

Virtual number identification

Through number segment analysis and model identification, low-quality resources such as network virtual numbers and batch registration numbers are marked.

Format standardization

Automatically identify international area code and local number formats and unify standards to avoid system abnormalities caused by format errors.

Structured result output

The detection results include fields such as status label, risk level, and country of origin, and can be directly imported into the advertising system or voice outbound platform.

By completing a complete screening before release, companies can significantly reduce the probability of abnormal numbers entering the system.

Application scenario: Data cleaning before cross-border advertising voice delivery

A cross-border e-commerce advertising team is preparing to launch voice reminders before the Black Friday event. The original list is48,000 mobile phone numbers, derived from advertising investment and historical customers.

Test outbound call results before screening:

lThe call failure rate exceeds43%

lSystem feedback line load abnormality

lThe complaint rate is significantly higher than usual

After introducing Digital Planet for batch screening:

lEliminate unregistered or invalid numbers9,200 items

lEliminate high-risk and abnormal number segments6,800 items

lremaining available numbers32,000 items

After serving again:

lThe call success rate is increased to71%

lThe system load is stable and there are no abnormal alarms.

lComplaint rates dropped by more than80%

lAdvertising conversion costs dropped by approx.28%

Team summary:"The problem is not the outbound call system, but the data quality. Only after filtering can the system performance be truly released."

Which projects must be prioritized for abnormal number cleaning?

lLarge-scale voice promotion notification

lPeak order reminder

lFinancial reminders and renewal reminders

lEducational audition invitation

lLocal life service appointment confirmation

lCross-border marketing centralized outbound calls

lAutomatic voice customer service batch return visits

In these scenarios, system stability directly determines business performance, and the core of stability comes from a clean number pool.

Conclusion

Voice group calling is no longer just about scale, but about precision and security. Removing abnormal numbers not only improves the call rate, but is also an important foundation for ensuring the long-term stable operation of the advertising system and outbound call platform.
