The number can be connected normally, but I have been contacted several times but received complaints. What is the problem?

The number can be connected, text messages can be received, and there are even people who reply when contacted for the first time, only to be marked as harassment or complained after following up several times. When this happens, it's usually not a problem with the validity of the number, but rather a failure to handle the source of contact information, contact frequency, and rejection records.

Empty number detection determines whether the number can be used normally, and high-risk complaint detection focuses on whether the number has a high risk of complaints. Neither result can replace user authorization. When using Digital Planet to check the number, you need to keep the basic communication status, complaint risk and actual follow-up records together. If you cannot see that the number is normal, contact repeatedly.

If it can be connected, it only means that the communication channel exists.

If the phone number can be connected normally, it at most indicates that basic communication conditions are present. It does not prove that the number owner knows the sender or that the other party agreed to receive promotions.

A number in normal status may come from a user's active consultation, or it may come from a long-ago order, a public page, an advertising form, or data from unknown sources. Different sources have completely different contact methods.

The user just submitted a consultation, and the customer service responded within a reasonable time, and the reason for contact was relatively clear. If a number left long ago suddenly receives promotions that have nothing to do with the original needs, the acceptance level will usually be much lower. Even if a number whose source cannot be explained is connected normally, it is not suitable to directly increase the contact frequency.

Digital Planet can first check whether the number is empty, whether it is connected to the Internet normally, what type of number it belongs to, and further investigate high-risk complaint numbers. However, the test result is normal, which does not mean that the user's consent was automatically obtained for this contact.

Just because you didn’t reply the first time doesn’t mean you need to send it again right away.

If you do not receive a timely reply to an unfamiliar contact, it may be that the other party is busy, has not seen it, is not interested in the content, or is not ready to continue the communication.

If the second and third messages are added soon after the first one is sent, and then the phone number, text message and social platform are changed to contact again and again, the user will not feel that"Follow up carefully" but keep interrupting.

The frequency of follow-up cannot only be set according to the customer service's own task volume, but also depends on the source of the customer and the previous status.

Those who take the initiative to inquire can conduct reasonable follow-up around the original demand; those who have clearly refused should stop immediately; numbers without any response and unclear sources are not suitable for increasing the number of contacts; customers who have purchased goods in the past can only contact based on orders, after-sales or reasonable service content, and cannot expand the scope of promotion infinitely.

The numbers screened out by Digital Planet still need to be entered into the unified follow-up record. The system can help determine the status of the number, but it cannot automatically know whether another customer service representative has contacted the same person.

Repeated contact with multiple customer service personnel is a common source of complaints.

After the number files are distributed to different customer service, if there is no unified record, the same user may receive multiple calls or messages in a day.

The same number may also be included in advertising forms, historical orders, and external customer data. Different file names do not mean different contacts. Without unifying the format and removing duplicates first, the same number may be recognized as several pieces of data because it contains a country code, does not contain a country code, or contains spaces.

For example, the same number is written separately:

lbringInternational format of “+”;

lWithoutInternational format of “+”;

lPreserve the format of the local prefix;

lFormat with spaces or parentheses.

If assigned directly according to the original text, these records may be repeatedly contacted by different people.

Before conducting number status and complaint risk detection on Digital Planet, the international format can be unified and deduplication completed. After the detection is completed, the number, source, assigned customer service, last contact time and user attitude are placed in the same record. This can prevent one person from being contacted repeatedly as multiple customers.

Users said"No need", next time it will not be a normal follow-up

Complaints do not necessarily occur at the first contact. Many users simply reject the message for the first time, only to complain or mark it as harassment later when they find that the messages are still appearing.

"I won't consider it for now", "No need", "Don't send it again", "It's not the person you are" and "Wrong number" all need to be recorded. You can’t just count those who completed the purchase as valid results, and leave the rest in the next round to continue sending.

Deny records must be able to distinguish at least:

lThere is no demand at the moment;

lMake it clear that you do not wish to have further contact;

lThe contact person is not the target customer;

lThe number has changed user;

lWrong contact information;

lThe user requested that the information be deleted.

Among them, numbers that clearly refuse to continue contact should be stopped. Even if Digital Planet detects that the number is normal, has opened a certain platform, or is currently active, it cannot put it back into the marketing scope.

Technical status will change, and user rejection is a communication boundary. The two cannot cover each other.

Being complained does not necessarily mean that the content is poorly written.

If someone complains after receiving promotional content, it may not necessarily be because the copywriting is not polite enough. What really has a greater impact is often“Why do you have my number”.

If the first message does not state the identity and reasonable reason for contact, the other party will easily judge it as unfamiliar marketing. continue to useVague expressions such as "Hello, are you there?" "I have a project I would like to know about" cannot reduce this suspicion.

The reason for contact must be consistent with the authentic source.

The number comes from advertising consultation, which can indicate which product or service page the user left information on; it comes from historical orders, which can communicate around the order, after-sales or repurchase cycle; and it comes from event registration, which can undertake the content selected at that time. Don’t make it up in order to increase the response rate"You have consulted before" or "A friend recommended you".

If the source of the number itself cannot be verified, Digital Planet can help check whether the number is valid and whether there is a high risk of complaints, but it cannot provide a reasonable basis for contact.

High risk complaint detection should be done before sending

Check numbers after a large number of complaints have already occurred and the damage has often already been done. A more reasonable approach is to complete basic cleaning before outbound calls, text messages or social platform contacts.

You can first use Digital Planet to organize number formats, detect empty numbers, and identify number types to exclude data that is obviously unusable. Then high-risk complaint number detection is used according to business conditions, and higher-risk data are processed separately.

Here's"Handling separately" does not mean changing a number to continue contacting, nor does it mean using other platforms to bypass rejection. A more appropriate approach is to suspend or reduce contact, and check the number source, authorization status and historical complaint records.

If a number has clearly refused contact, it will directly enter the stop reach range and no longer need to rely on risk detection for decision-making. High-risk complaint detection is mainly used to process data that has not yet formed a complete communication record, adding a layer of reference for risk judgment before sending.

What the latest complaint data says

According to the U.S. Federal Communications CommissionAccording to data released in 2026, the top five types of robocall scams in 2025 accounted for approximately 51% of related complaints.

This set of data does not mean that all cold calls are scams, nor can normal business contacts be mixed with scams. What it really shows is that users and communication operators are already very sensitive to unfamiliar, high-frequency, and unidentified phone calls and text messages.

Once a number is flagged by a large number of users, subsequent normal contact may also be affected. Outgoing messages may be filtered, phone calls may appear as suspected harassment, and customer service call rates may drop.

Therefore, reducing complaints is not about making your words more subtle, but about ensuring that the source of the number is clear, the reason for contact is true, the frequency is reasonable, and the user's rejection is respected.

You can review it once and complain about the exception like this

Assume that a certain round of contact uses5,000 numbers, this number is only used to illustrate the review method.

Don’t just count the number of calls, but check the Digital Planet detection records and customer service follow-up records to confirm how many of them have completed empty number filtering, how many numbers have undergone high-risk complaint detection, and how many numbers have been rejected before being sent.

Then check how many times the same number has been contacted. In particular, check whether there are any duplications between different customer services, different accounts and different channels. A user may first receive a phone call and then receiveWhatsApp messages and then text messages are received. The frequency of each channel alone is not high, but taken together, it is a continuous interruption.

Complaints are then compared by data source. If there are fewer complaints from actively consulting customers and there are significantly more complaints about data from unclear sources, it means that the problem mainly lies in the acquisition and authorization links; if complaints occur from all sources, it is necessary to check the contact frequency, sending content and customer service coordination.

Finally, check the processing after rejection. Whether users still receive messages after explicitly requesting to stop is usually more likely to trigger complaints than the first unfamiliar contact.

Category 3 numbers should be immediately separated from transmission

The first category is numbers that explicitly refuse further contact. This type of data is stopped directly and is not re-enabled because the number is still valid.

The second category is numbers whose sources cannot be verified and which also show a higher risk in Digital Planet’s high-risk complaint detection. The contact is paused first and cannot be transferred to another customer service or platform to continue sending.

The third category is numbers assigned repeatedly by multiple customer service staff. First merge customer records, confirm the last communication and user attitude, and then decide whether there is a reasonable basis for continued contact.

Other numbers that are in normal status and have clear sources must also control their frequency. Digital Planet's empty numbers, number status and high-risk complaint detection can help reduce obviously inappropriate data, but what really determines the level of complaints is whether there is a reasonable basis for contact, whether the contact is repeated, and whether the user stops it in time after rejection.

The number was connected normally, but after continuous contact, I was complained, indicating that the problem has been resolved."Is the number available?" turns to "Is this contact appropriate?" Only by first using Digital Planet to check the basic status and complaint risks, and then managing the source, frequency and rejection records, can we truly reduce subsequent complaints.
