What is AWS End User Messaging?

AWS End User Messaging empowers developers to integrate scalable and reliable messaging capabilities into their applications. Whether it's time-sensitive alerts, one-time passwords, or two-way communications, AWS End User Messaging helps ensure your messages reach their local or global destination across multiple channels like SMS, MMS, WhatsApp, push, and text to voice. AWS End User Messaging helps unlock the full potential of your messaging strategy by connecting your applications directly to your end-users across the channels they use and trust.

Conversational Experiences

Build AI-powered conversations where customers interact naturally with your business through SMS, RCS, or WhatsApp. Connect inbound messages to your Lambda functions and Bedrock for intelligent responses, creating complete application interfaces right in messaging apps customers already use. With RCS and WhatsApp, your AI agents assist customers and complete transactions under your verified brand identity — so customers know they're engaging with your business.

Benefits of AWS End User Messaging

Send Messages at Scale

AWS End User Messaging provides the global scale, resiliency, and flexibility required to deliver SMS, RCS, WhatsApp, push, and voice messaging capabilities in your web, mobile, and business applications. Trust that your messages are delivered to the geographies that matter most to your business.

Reduce Spam Concerns with Verified Identity

Build confidence with end users through multiple layers of protection. RCS and WhatsApp provide verified brand identities — your logo, name, and verified badge where the verified checkmark next to your brand name helps reduce customers suspecting your valid messages are spam or phishing. SMS Protect validates phone numbers and detects fraud before you send, identifying anomalous traffic to prevent unexpected costs.

Get Started Fast, Scale on Your Terms

Notify lets you start sending OTP messages in minutes — no phone number registration required, no carrier approval, just call the API and send. When you're ready to grow and need your own phone number or brand identity, our AI-powered registration reviewer gives you faster feedback on your submissions so you can get through the registration process sooner. Start fast with Notify, then scale to dedicated numbers, verified brands, and full messaging capabilities on your terms.

Messaging Channels in AWS

AWS End User Messaging brings messaging channels into the AWS ecosystem where your core applications live. Inbound messages flow to SNS, EventBridge, or Kinesis, enabling seamless connections to your applications and services. Your messaging channels and applications live in the same place — in AWS — creating a better builder experience with tightly coupled, real-time interactions, less complexity, and faster time to value.
