Most cross-border e-commerce businesses have encountered this issue: spending 100,000 CNY on Facebook and Zalo ads but getting less than 100 orders. Up to 40% of the contacted numbers are "fake phone numbers" without real platform accounts. In Vietnam, local promotion costs soared 3x because businesses couldn’t identify active Zalo users.
The root cause isn’t ineffective channels, but neglecting social platform account verification. Mainstream social platforms vary by market: Zalo dominates Vietnam, Facebook is key in Southeast Asia, and WhatsApp leads in Brazil. Blindly using a universal number list leads to misreach. NumVerix, as a global social platforms, helps businesses screen real registered users, turning "broadcasting" into "precision targeting".
I. Real Case: Why 80% of Zalo Campaign Resources Were Wasted
A Guangzhou cross-border shoe brand ran a Zalo campaign in Vietnam, sending 100,000 marketing messages with Vietnamese exclusive discounts. It only got 300 orders, a 0.3% conversion rate.
Post-campaign checks revealed three critical issues: 50,000 numbers weren’t registered on Zalo, 30,000 were long-inactive accounts, and only 20,000 were active Zalo users—80% of marketing resources were wasted.
The core mistake was "promoting first, verifying later", violating cross-border social marketing logic. Effective lead generation requires "verifying account status first, then precise outreach": screen registered active users on target platforms, then push customized content to ensure resources reach real buyers.
II. NumVerix Social Media Verification: Three Core Capabilities to Solve Pain Points
Tailored for cross-border e-commerce, NumVerix’s Zalo Number Verification and Facebook Phone/Email Verification connect directly to official platform databases, delivering "precision identification, bulk verification, and scenario adaptation".
1. Precision Identification: Lock Real Registered Users
Zalo Verification quickly checks if a phone number is registered on Zalo and returns its country code, eliminating unregistered numbers. Facebook Verification supports dual checks (phone/email), distinguishing "active" from "long-inactive" accounts. Both have a ≥95% accuracy rate for registration status.
2. Bulk Verification: Meet Large-Scale Screening Needs Before Promotions
For pre-promotion large-scale user screening, NumVerix supports bulk verification of up to 2 million numbers per batch. Businesses upload number lists via Excel/TXT, get full results in 3 minutes, and quickly lock active users—saving time for customized marketing.
3. Scenario Adaptation: Match Global Mainstream Social Platforms
Beyond Zalo and Facebook, NumVerix covers 10+ platforms like WhatsApp. Businesses choose tools by market: WhatsApp Verification for Brazil, Facebook Verification for Southeast Asia—ensuring "market-specific" precision and avoiding platform mismatch waste.
III. Results: 7x Conversion Boost, 68% Cost Reduction
After integrating NumVerix, the Guangzhou shoe brand restructured its Zalo campaign: first screening 80,000 "active Vietnamese Zalo users", then pushing Vietnamese discounts and new product info.
The conversion rate jumped from 0.3% to 2.5% (nearly 7x), and customer acquisition cost dropped from 333 CNY to 107 CNY (68% reduction), completely solving resource waste.
Conclusion: Precision Screening Beats Blind Spending in Social Marketing
In competitive emerging markets like Southeast Asia and Latin America, cross-border e-commerce social marketing has shifted from "spending more" to "targeting better". NumVerix’s professional verification eliminates fake numbers and locks real buyers, ensuring every marketing yuan drives actual results. Choosing the right social verification tool is the key to cross-border e-commerce success.
