The infrastructure behind every message.

Sent handles the decisions and infrastructure behind every message, so your team can focus on building the product.

Know the best way to reach every customer.

Sent checks channel availability, customer preferences, carrier health, delivery performance, and cost before every send, then selects the strongest route automatically.

Write once. Send correctly everywhere.

Create one message template and Sent adapts the content, media, and formatting for SMS, WhatsApp, and RCS, including channel-specific approvals and compliance requirements.

Delivery does not stop at the first failure.

If the preferred route fails, Sent can retry, switch providers, or fall back to another channel while your team follows every step from request to delivered and read.

One infrastructure layer. Every message that matters.

Authenticate users instantly
OTP, 2FA, login verification, password resets, and security alerts.
Keep customers informed
Order confirmations, shipping updates, payment alerts, appointments, and delivery exceptions.
Run campaigns across every channel
Segmented, personalized campaigns across SMS, WhatsApp, and RCS.

The hard part of messaging stays out of your code.

Build with a type-safe SDK, test safely in sandbox, and track every message through signed webhooks. Sent handles retries, routing, compliance, and channel complexity behind one consistent API.
