AWS End User Messaging Cheat Sheet

AWS End User Messaging provides developers with a single, scalable way to send messages (including transactional, notifications, and promotions) to users across various channels.

Key Features

AWS End User Messaging offers a broad set of capabilities that let you communicate with users globally through various channels while maintaining control, security, and reliability. It integrates seamlessly with AWS tools, making it easy to automate messaging at scale.

1. Multi-channel support: SMS, MMS, push notifications, voice calls, and WhatsApp messaging. 
2. Two-way messaging and conversational support (especially for channels like WhatsApp). 

3. Global reach & scale: works across many countries & regions. 
4. Integration with AWS ecosystem: APIs, SDKs, CLI support for automation. 
5. Security & compliance controls: You retain data ownership, encryption, and protections against abuse (e.g., SMS pumping). 

Benefits

By centralizing messaging flows and offering flexible channel options, AWS End User Messaging helps teams deliver messages more efficiently and effectively. It reduces operational overhead and improves engagement through personalized, timely communication on the channels users already prefer.

1. Faster time to market: You can add messaging features without building an entire infrastructure.
2. Reach users via their preferred channel: Whether SMS, WhatsApp, push—flexibility to match user habits.
3. Operational efficiency: Centralized messaging controls within the AWS platform—less tooling to manage.
4. Improved user engagement & trust: Two-way support and rich media (especially via WhatsApp) improve interaction.
5. Better cost & abuse control: Features to manage quotas, prevent spam/abuse, and align spending to usage.

Security

AWS End User Messaging includes strict security and compliance features to protect user data, prevent abuse, and ensure message integrity. Encryption, IAM controls, and fraud detection are built into the service to keep communication secure across all channels.

1. IAM access control: Fine-grained policies to secure APIs and messaging workflows.
2. Encryption: Data encrypted in transit and at rest.
3. Abuse & fraud protection: SMS pumping and spam prevention safeguards.
4. Data ownership: Customer data is not shared with carriers beyond what is needed for delivery.
5. Auditing: CloudTrail logs all messaging API activity for compliance and monitoring.

Pricing

• Pay-as-you-go model: you’re charged based on usage (number of messages/voice calls, channel used). 
• Carrier fees apply for SMS/A2P channels; charges are incurred for messages that leave AWS and are sent to carriers, even if not delivered. 
• There is self-service access, allowing you to try it without an upfront commitment.
