Does the outbound voice call hit rate fluctuate significantly? Introducing an abnormal number cleaning mechanism to stabilize data delivery performance

In large-scale voice marketing and automated outbound call systems, hit rate fluctuations are one of the biggest headaches for many teams. The data is good today, but will drop tomorrow, and there will be a large number of failed dial-ups the day after tomorrow. The advertising system and voice platform simply cannot maintain a stable rhythm. The fundamental problem behind this lies not in system technology or language settings, but in a link that has been repeatedly ignored:Whether the number quality has been abnormally cleaned.

With overseas voice delivery,With the continued expansion of AI voice robots and call center automation scenarios, companies are faced with thousands of mobile phone numbers every day, from sources including advertising forms, event registrations, third-party data sources, and historical customer return visit records. Once a large number of abnormal numbers are mixed into this data, it will directly lead to a decrease in voice outbound call efficiency, an increase in complaints, platform risk control warnings, and poor customer response.

Digital Planet provides professional global mobile phone number detection services, supports batch cleaning and status identification of abnormal numbers, and has been widely used in voice advertising andIn the AI ​​outbound call system, it has become an important infrastructure to improve the stability of delivery.

Why do abnormal numbers cause hit rate fluctuations?

The stability of the voice system and call hit rate depend on whether the data is clean. If the following exception types exist in the list, it will inevitably lead to unstable outbound call performance:

lHigh-risk accounts that have been banned or have too many complaints

lVirtual number segment, batch registration number, transcoding number

lOut of service number, empty number or abandoned number

lThe same number imported multiple times

lNon-standard international numbers or numbers with confusing formats

These abnormal numbers will have the following consequences in the system:

lThe frequency of system call failures increases and line resources are wasted.

lA large number of invalid calls occupy the voice engine and affect other call schedules.

lThe dial-up system triggers the operator's blacklist mechanism, resulting in account blocking or dialing restrictions.

lDistortion of delivery performance statistics, misleading strategic judgments

lThe call team mistakenly thought there was a communication problem, and repeated adjustments only made things worse.

To solve the problem of unstable hit rate, the first step is to thoroughly clean the abnormal numbers.

What anomaly cleaning capabilities does Digital Planet provide?

Digital Planet has developed a dedicated module for outbound voice call scenarios to help companies eliminate high-risk and low-value numbers from the source:

1. Batch testing registration status

Detect whether the number has been registered on mainstream platforms or communication systems, and identify empty numbers, invalid numbers, and unidentified numbers.

2. Identify high-complaint and blacklist number segments

The system has the ability to identify the complaint number segment and can mark the operator's judgment as"High risk" numbers.

3. Automatic marking of virtual numbers and transcoded numbers

againstVirtual resources such as VOIP, Internet calls, and API registration numbers are independently identified to avoid dialing "fake users".

4. Multi-country number format standardization

System supports global244 country and region code formats, automatically identify and clean illegal formats, abnormal area codes and incorrectly coded numbers.

5. Export of structured results

The cleaned data can be exported according to status labels, such as"Highly active users can be dialed", "high-risk abnormal numbers", "format error to be confirmed", etc., to facilitate system classification and processing.

Enterprise application case: Turnaround performance of voice marketing projects in the education industry

An online language learning platform launches voice audition invitations in the Latin American market, initial list12,000 came from short video ads and historical user return. Without cleaning before use, direct outbound calls, the results are as follows:

lThe connection rate is only24.8%

lCustomers complained about receiving harassing phone calls

lThe platform voice channel is automatically restricted due to high complaints.

lThe person in charge of marketing misjudged that the rhetoric design failed

The company then accessed the Digital Planet screening module:

lEliminate unregistered or uncommunicable numbers3,800 items

lEliminate virtual numbers and transcoded numbers2,100 items

lMark black numbers and blocked numbers1,300 items

lThe actual available high-quality numbers are4,800 items

After re-traffic:

lThe connection rate increased to61.5%

lThe average user first response latency is reduced toWithin 4 hours

lThe delivery complaint rate dropped toBelow 1%

lIncreased conversion rate for trial class reservations2.9 times

lThe platform system operates stably and no risk control warnings appear again.

The person in charge of delivery said:"It's not that the system isn't working, it's just that we used the wrong number."

It is recommended to introduce the core link of the abnormal number cleaning mechanism

lVoice advertising first time user activation before batch exposure

lUser pool classification before voice robot group dialing

lCustomer service platform dockingCompliance check before API number pooling

lUnified cleaning before cross-border voice reminders (such as holidays, orders, events)

lPrevent mistaken dialing of abnormal users in e-commerce return visits and payment reminder scenarios

lPreprocessing before the SCRM system synchronizes mobile phone numbers from the social pool

In any high-frequency outbound voice call scenario, as long as it involves cross-border, multi-source data import, and multiple rounds of contacts, abnormal number screening is the key to stabilizing the system hit rate.

The capability of the voice system is not how many calls are made, but how many calls are connected; it is not how many numbers are connected, but how many real users are connected.
