Understanding Klaviyo and Its Challenges in China
This blog post provides insights about Klaviyo, a leading email marketing platform widely used among businesses globally, and the challenges it faces in China.
Does Klaviyo work in China?
Klaviyo did not complete a load from mainland China. Measured fact: from a probe inside mainland China (Alibaba Cloudcn-zhangjiakou), three runs, 2026-08-28, zero of three runs finished within 60 seconds, first byte in a median 917ms and paint at 3.4s. Two failures ride on this one: signup forms embedded from Klaviyo never render, and the on-site tracking that feeds your segments stops reporting. The second is the dangerous one — a segment that looks small because the tracking failed is indistinguishable from a segment that is genuinely small. Help Your Klaviyo Platform Thrive in China!

Why Klaviyo tracking and forms fail quietly in China
As effective as Klaviyo is, the technology faces some challenges in China. The most significant among these is the speed and loading issues resulting from compatibility problems. This drawback becomes more pronounced due to China’s unique internet infrastructure, making it difficult for Klaviyo powered sites to deliver a seamless experience to Chinese users.

In addition to this, Klaviyo faces legal and compliance hurdles in China, based on the country’s stringent internet regulations. Without appropriate compliance, businesses risk facing penalties that not only affect their operations but also their reputation.

Klaviyo namely uses AWS for its cloud infrastructure. It is important to note that this can also contribute to the platform’s underperformance in China, due to the Great Firewall that impacts AWS’s accessibility in the region.
