Unified Messaging API
One integration sends SMS, WhatsApp, and RCS with a single request.
Intelligent Abstraction Layer
Your app talks to Sent; Sent handles providers, carriers, and channel quirks.
Clean API Design
Minimal, predictable methods that feel natural in any language.
Transparent Message Lifecycle
Track every message from request to delivery with full visibility.
The Problem with Legacy Infrastructure
You want to ship features. You're stuck managing pipes.
Fragmented Providers
Managing distinct APIs for Twilio, Meta, and carriers creates technical debt.
Compliance Hell
Navigating 10DLC, WhatsApp templates, and opt-out rules is full-time work.
Transformation Logic
Building rich-media fallbacks to plain text SMS requires constant maintenance.
Cost Inefficiency
Lack of intelligent routing means paying premium SMS rates for every message.
How Sent Works
Intelligent routing and delivery, abstracted away.
Persistent Contact Object
Every user is stored as a rich delivery profile, not just a phone number.
Channel Availability Check
Sent instantly detects which channels can reach each contact.
<20ms API Overhead
Requests are acknowledged instantly and streamed through Kafka.
Omnichannel Templates
Define one message; Sent transforms it for each channel.
Template Rendering Flow
A single intent fans out into multiple channel-specific payloads.
Automatic Fallbacks
When rich delivery fails, SMS fallback is triggered without extra code.
