New Message

01 — Connect

Integrate Sent once using one API and the SDK your team already works with. Connect your product without building separate integrations for every channel.

02 — Send

Send one request with the recipient and message template. No provider-specific payloads or channel-specific logic required.

03 — Deliver

Sent selects the best available route, applies the correct channel rules, and automatically falls back if delivery fails.

14,000+ developers and product teams rely on Sent for messaging

The infrastructure behind every message.

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

One API for every channel

Connect your product once and send messages through SMS, WhatsApp, and RCS using one consistent interface. Add new channels without rebuilding your messaging infrastructure.

The best route for every message

Sent checks which channels are available and routes each message based on cost, speed, and reliability. If the first route fails, Sent automatically tries another.

Channel complexity, handled

Define your message once. Sent adapts it for each channel, handles templates and compliance requirements, and lets you track every step from request to delivery.

Sent evaluating a new user and choosing WhatsApp as the best channel

Sent selecting a customer's preferred and active WhatsApp route

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.

Talk to Sales

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.

One message template routed correctly to SMS, WhatsApp, and RCS

A message retrying failed paths until delivery succeeds

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.
