Unified messaging API to send SMS, WhatsApp, iMessage and RCS from one integration for 2FA, notifications and campaigns.

- Channel Abstraction & Routing: Automatic channel selection and routing logic to deliver messages via the best available path, reducing the need to manage separate provider connections.
- 2FA and Time-Sensitive Delivery: Optimized low-latency delivery paths and templating for one-time passwords and transactional alerts to ensure fast user authentication and confirmations.
- Campaigns & Templating: Support for templated messages and campaign workflows to send personalized marketing or notification bursts with scheduling and variable substitution.
- SDKs and Developer Libraries: Official client libraries (including a Node library referenced on the project's GitHub) and quick-start guides to accelerate integration and testing.
- Webhooks & Delivery Receipts: Real-time status callbacks and inbound message handling via webhooks to track delivery, handle replies, and reconcile messages programmatically.
- Phone Number Management & Compliance: Tools for provisioning and managing phone numbers across channels and handling channel-specific templates and regulatory requirements.
- Single unified API endpoint to send messages across SMS, WhatsApp, iMessage, and RCS
- Support for use cases: 2FA, transactional notifications, and marketing campaigns
- Official documentation and quick start phrasing: "Get started in minutes"
- Client library availability (Node library referenced in the GitHub organization)

- Multichannel Marketing Campaigns: Run personalized marketing campaigns that target users on WhatsApp, iMessage, RCS or SMS while using unified templates and scheduling.
- Cross-Channel Fallbacks: Ensure message delivery by attempting app-based delivery first (WhatsApp/iMessage/RCS) and falling back to SMS when app delivery is unavailable.
- Inbound Message Handling & Support Workflows: Receive user replies and route them to support systems or automate responses using webhooks to integrate with CRMs or ticketing.
- Implementing instant two-factor authentication (2FA) via SMS or app channels
