Efficient Communication Channels between Customers and Enterprises

SMS provides a feature of sending multiple messages at a time and various API operations. You can use SMS to send one-time password (OTP) messages, notification messages, and promotional messages to customers in more than 200 countries and regions around the world.

You can also provide customized messages for customers based on your user profile database to improve user experience and conversion rate.

Intelligent Scheduling

SMS selects the best route based on the throughput and delivery success rate in real time. This way, messages can be sent at the scheduled points in time.

Controllable Message Sending

SMS allows you to limit the total number of messages sent to multiple customers per day to minimize unexpected resource consumption. You can also limit the number of messages sent to a single customer to prevent unnecessary disturbances.

Secure API Calls

SMS provides identity authentication for both Alibaba Cloud accounts and Resource Access Management (RAM) users. This ensures that only you can call API operations to manage the resources that you create.


High Concurrency

Supports multiple queues to ensure that requests are received and processed at the earliest opportunity.

Intelligent Sending

Super-long Messages
