AWS End User Messaging Notify

AWS End User Messaging Notify lets you send templated OTP messages via SMS and voice in minutes — without provisioning phone numbers, managing sender IDs, or navigating registrations. Just provide your brand name, configure your setting, and start sending OTP messages to your customers. AWS manages the phone numbers and SMS pumping protection through SMS Protect, so you can focus on building your application. 

Create a Notify configuration with your brand name and start sending templated OTP messages immediately. No phone number provisioning and no number approval wait times. AWS manages the phone numbers on your behalf reducing setup time to minutes. Enable SMS, voice, or both channels when you create your configuration. 

Notify runs through AWS SMS Protect automatically, detecting and blocking anomalous traffic before messages are sent — protecting your business from unexpected charges. SMS pumping protection is always on and cannot be disabled, included with every API call at no additional cost. Spend limits add another layer of protection, pausing message delivery if your account reaches its configured threshold.

Send OTP messages to over 200 countries using pre-approved templates that work across major carrier networks worldwide. Your messages deliver reliably without requiring individual template registration. Templates support multiple languages and let you customize your brand name, code format, and expiration time.
