Sent
One API for SMS, WhatsApp, and RCS messaging with automated routing, compliance, and per-.
Sent is a messaging API platform that lets developers send SMS, WhatsApp, and RCS messages through a single integration. It addresses the fragmentation of managing separate providers, carriers, and channel-specific requirements by handling routing, compliance, and content transformation automatically, so teams can focus on their product rather than messaging plumbing.
The platform provides a unified API with contact objects, channel availability checks, unified templates that fan out into channel-specific payloads, automatic fallbacks when delivery fails, and message lifecycle visibility from request to confirmed delivery. Sent is a registered carrier with direct interconnects, and compliance features include opt-in enforcement, country-specific rules, content validation, and automated 10DLC registration. WhatsApp template submissions and approvals are managed by the platform. Integrations include an npm package for developers.
Sent is aimed at developers and product teams building messaging features, with solutions for e-commerce, SaaS, fintech, and healthcare. Pricing is usage-based: a pay-as-you-go plan charges a monthly per-contact platform fee with carrier fees passed through at cost and includes full API access and community support. An Enterprise edition offers volume pricing, SLAs, and dedicated support, with custom pricing handled through Sales.
