Case Study: Globe Telecom achieves 400% more trusted email addresses and daily data-quality scoring with Talend

Creating wonderful experiences for mobile subscribers

Globe Telecom, a leading Philippine telecommunications provider serving tens of millions of customers, faced a critical data challenge: customer records (notably email addresses) were incomplete and error-prone due to manual entry and monthly, spreadsheet-based quality checks. This left marketing and analytics teams without timely, trustworthy source data needed to personalize offers and grow customer lifetime value amid intense market competition.

Globe deployed Talend Big Data and Talend Data Quality to automate data profiling and daily data-quality scoring into a centralized data lake and Tableau dashboards, freeing analysts to fix root causes rather than run manual checks. The automation boosted trusted email addresses by 400%, delivered daily instead of monthly quality scores, cut effort by roughly 60%, and improved campaign ROI (–30% cost per lead, +13% conversion rate, +80% click-through rate).
