Alibaba Cloud Short Message Service (SMS) delivers messages reliably across more than 200 countries and regions, with carrier-grade infrastructure, intelligent routing, and built-in analytics to support messaging operations at scale.
Global coverage
Send messages to recipients in more than 200 countries and regions. SMS connects you globally with localized routing—whether you're sending appointment reminders, account alerts, or time-sensitive notifications.
Efficiency and stability
Built on carrier-grade infrastructure with real-time operations and maintenance (O&M) monitoring, SMS tracks delivery performance continuously and delivers messages worldwide within seconds—keeping SLAs intact even under load.
Easy integration
Get started quickly with SDKs for popular programming languages and straightforward APIs. SMS reduces development time and integration complexity, letting your team focus on building the application rather than managing messaging infrastructure.
High concurrency
An AI-powered message scheduling engine dynamically balances load during high-volume periods. Large-scale sends—such as campaign blasts or time-critical alerts—are processed efficiently without degrading throughput or delivery rates.
Intelligent channel switchover
SMS automatically routes messages through the best available channel using real-time geolocation data from mobile carriers and the Ministry of Industry and Information Technology (MIIT). When a channel becomes unavailable or underperforms, SMS reroutes traffic to maintain delivery rates—without manual intervention.
Peak-load shifting
Multiple priority-based queues distribute message traffic dynamically, preventing bottlenecks during peak hours. High-priority messages—such as OTP codes or emergency alerts—are processed first, while lower-priority traffic is queued behind them, keeping the system stable and delivery rates optimal.
Automatic message classification
SMS automatically reviews and classifies message content by service type and industry, enabling fine-grained management of your messaging traffic. Messages stay compliant and correctly categorized without manual review overhead.
Messaging analytics
Comprehensive messaging logs give you full visibility into delivery performance across all sends. Use the data to monitor and troubleshoot delivery issues in real time, perform cost reconciliation, and optimize your messaging operations.
