Case Study: Krungsri Credit Card achieves a 40% CTR uplift and 37% increase in reach with Appier

Increased CTR through AI digital marketing

Krungsri Credit Card (KCC), a subsidiary of Thailand’s Krungsri Bank, provides personal finance and credit card products through a lead-generation website. KCC faced weak engagement because it couldn’t create precise customer segments or identify the best times to send campaigns, so many customers received untargeted promotions and campaigns were sent at suboptimal times.

Using Appier’s AIXON to build AI-driven micro-segments and keyword personas and AIQUA to predict optimal send times, KCC delivered more relevant content to each user at the moments they were most receptive. The campaign drove a 37% increase in customer reach, 91% more clicks and a 40% overall CTR uplift; send-time optimization produced a 2–10% CTR gain versus human timing, with 4–5pm shown best for shopping content (2.8% above manual timing, 12% above average).
