Customer.io is a messaging automation platform that triggers emails, push, and SMS based on user behavior, with segmentation, A/B testing, and analytics.

Customer.io’s platform is accessible in China but email/SMS delivery APIs are unreliable; scripts and dashboards load slowly. Local solutions like Jiguang, Umeng+, or Tencent Cloud Communication are used per region for push/email reliability.

The information regarding service availability in China is provided for general reference purposes only. Due to the dynamic nature of network conditions and regulatory environments, the actual accessibility of these services may vary over time and by location. Users are advised to verify the current status independently.
