Why are your Viber marketing efforts ineffective? It might be due to a high rate of unresponsive numbers! Number filtering solutions.

Many businesses face a return-on-investment problem when conducting Viber marketing campaigns. A significant but often overlooked reason is the inadequate identification of Viber "cold" accounts, resulting in marketing messages being sent to a large number of inactive or even invalid accounts. Effective Viber cold account identification can significantly improve reach, ensuring that marketing resources are truly invested in valuable leads. However, many marketers lack systematic methods and tools for effectively identifying and handling these "cold" accounts, ultimately impacting overall marketing effectiveness.

What are Viber cold numbers? Why do they affect marketing effectiveness?

Viber "cold numbers" typically refer to numbers that, although registered as Viber accounts, are inactive or rarely used. The existence of these accounts has multiple negative impacts on marketing effectiveness.

• Extremely low open rate : Users with infrequent phone numbers basically never open the Viber app, and messages sent to them go unanswered.

• Interaction rate is almost zero : even if a message is received, users will not reply or interact in any way.

• Increased sending costs : Every message has a sending cost, and cold numbers directly increase invalid expenses.

• Impact on data analysis : Cold accounts lower overall open rate, click-through rate and other key metrics, leading to data distortion.
  
  

How to identify unpopular Viber numbers? What signals should you pay attention to?

Identifying inactive Viber accounts requires monitoring signals from multiple dimensions and conducting comprehensive analysis to determine the account's activity level.

1. Account registration time characteristics

   • No updates to personal profile after registration

   • Never set a custom profile picture or used the default profile picture for more than a year

How to systematically filter out unpopular Viber numbers?

Professional number screening tools can systematically solve the problem of identifying cold numbers. Taking ITG's full-domain screening platform as an example, its standardized process can effectively complete the quality assessment of Viber accounts.

Step 1: Data Preparation and Upload.
Organize the list of phone numbers to be tested into CSV or TXT format, supporting data import from various channels such as advertising, historical customer pools, and offline events.

Step 2: The registration status basic detection
system first verifies whether each number has been registered with a Viber account. Unregistered numbers will be directly marked and excluded to ensure that only valid accounts are analyzed later.

Step 3: The tiered labeling
system assigns a "Recommended," "Use with Caution," or "Exclude" label to each number. Marketers can then tailor their communication strategies to accounts of varying quality based on these labels.

How can the screening results be effectively applied to marketing strategies?

After obtaining the screening results, differentiated marketing strategies need to be developed for accounts of different quality.

• Prioritize high-quality accounts : For accounts on the "Recommended Use" list, design personalized communication plans and invest more resources in in-depth follow-up.

• Testing and nurturing medium-quality accounts : For accounts on the "use with caution" list, use standardized but friendly communication methods, observe the response, and then adjust the strategy accordingly.

• Dynamically adjust communication frequency : Adjust the message sending frequency dynamically based on changes in account activity.

• Personalized content strategy : Design differentiated content strategies for accounts with varying levels of activity.

Professional tools such as ITG's comprehensive screening system can help marketing teams quickly identify Viber cold accounts and establish a scientific account quality stratification system through a systematic detection process.

Conclusion

Poor Viber marketing results are often not due to content or strategy issues, but rather inadequate groundwork. Cold number identification, as a crucial initial step in marketing campaigns, directly impacts the effectiveness of all subsequent efforts. By establishing a systematic screening mechanism and using appropriate tools for batch processing, businesses can fundamentally improve the quality and efficiency of their Viber marketing. The key is to make cold number identification a routine process, continuously optimize screening criteria, and effectively apply the results to actual marketing decisions.
