How can Viber reduce invalid emails and lower cross-border promotion costs through active filtering?

Viber is a core cross-border marketing channel for businesses seeking to expand their customer base overseas. However, the proliferation of invalid and inactive accounts directly drives up marketing costs and reduces conversion rates. Viber's active account filtering is key to solving this problem. Effective Viber active account filtering can eliminate low-quality accounts at the source. Combined with ITG's comprehensive filtering, it can significantly improve filtering efficiency and accuracy, eliminating indiscriminate mass messaging. This article will detail the core value and practical methods of Viber active account filtering, helping businesses cut ineffective expenses and improve cross-border marketing ROI.

I. Why is Viber's active screening the core of cost reduction and efficiency improvement?

Many businesses invest heavily in Viber cross-border advertising, only to see dismal results due to low-quality phone numbers. A single inaccurate call can lead to the following problems:

Invalid message delivery: The number is not registered with Viber, and the message cannot be delivered.
Low response rate: Reaching inactive accounts or low-activity users resulted in no response.
Platform risk control: Frequent sending of messages to banned or inactive accounts can easily trigger platform sending restrictions.
Inflated costs: Ineffective campaigns consume promotional funds, needlessly increasing cross-border marketing costs.

Successful promotion is never about "casting a wide net," but about "precise targeting." Viber's active filtering = eliminating invalid accounts + focusing on highly active users, which is the core foundation for reducing promotion costs and improving delivery efficiency.

II. What are the core criteria for Viber's active user screening?

To effectively screen Viber accounts, it's crucial to define precise criteria to differentiate between high-quality and ineffective accounts, avoiding blind screening. The core dimensions are as follows:

Registration Status: Filter valid numbers that have been successfully registered with Viber, and remove invalid or unregistered numbers.
Online status: Differentiate between recently online and long-term offline accounts to identify highly engaged and active users.
Account survival: Investigate, ban, freeze, and cancel accounts to avoid sending risk control issues.
Activity frequency: Filter accounts that have logged in within the last 7-30 days, and remove inactive or dead accounts.

Clear criteria allow Viber to make its active user filtering more targeted, eliminating invalid submissions at the source and maintaining the bottom line for cross-border promotion costs.

III. ITG's comprehensive filtering helps Viber achieve more efficient and accurate filtering.

Manually filtering Viber activity is inefficient and prone to errors. However, relying on the professional filtering tool ITG for full-domain filtering can significantly improve the speed and accuracy of Viber activity filtering, making it suitable for cross-border bulk needs. Its core advantages are as follows:

V. Practical Tips for Optimizing Viber's Promotion After Active Filtering

After completing the Viber active screening and identifying high-quality accounts, combining this with appropriate promotional techniques can further amplify the effect and continuously reduce costs. The core optimization techniques are as follows:

Targeted targeting: Messages are sent only to accounts that have been actively filtered by Viber, avoiding invalid mass messages.
Regular rescreening: Viber's activity screening is redone every few weeks to remove newly added inactive accounts.
Tiered operations: Push notifications based on active duration to improve user response and conversion efficiency.
Strict cost control: Precisely control the number of messages sent to avoid wasting promotional resources and package quotas.

By consistently employing active screening and skillful operational techniques on Viber, we can steadily reduce cross-border promotion costs, improve overall marketing ROI, and achieve long-term, efficient promotion.
