One API for every channel

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.
Know the best way to reach every customer.

Frequently asked questions
Sent gives you one API for SMS, WhatsApp and RCS, with routing, retries, template management, compliance handling and delivery tracking built in. You send one request and Sent decides how it reaches the customer.
Yes. Templates support locale variants, so you can define a message once per language and Sent selects the right one from the recipient profile or an explicit locale on the request.
You can pin a message to a single channel, give an ordered list of preferred channels, or let Sent Routing choose. Pinning is useful for regulated message types that must go over one specific channel.
Transactional messages such as one-time passcodes, order and delivery updates and account alerts, plus conversational and campaign messages where the channel allows it.
Sent sits behind one API and emits signed webhooks for every state change, so it drops into an existing stack without replacing your CRM, support desk or data warehouse.
Install the SDK, authenticate with your API key, then call sent.messages.send with a recipient, a template and the channels you allow. Everything after that, including routing and fallback, is handled for you.
Yes. Images, video, documents and rich cards are supported on the channels that allow them, and Sent adapts or drops the media automatically when a message falls back to a channel that does not.
Add them to the template as variables. Sent handles link shortening and per-channel attachment rules, and click events come back through the same webhooks as delivery events.
Every message exposes its full timeline: accepted, routed, sent, delivered, read and failed, with the route taken at each step. The same data is available in the dashboard and over the API.
Sent manages sender registration, template approval, opt-out handling and per-country sending rules, and blocks a send when the destination would breach them.
That is the default. One integration covers every channel you enable, and adding a new one does not require changes to your send code.
A full sandbox mirrors production behaviour, including routing decisions, failures and webhooks, so you can test fallback paths without sending a real message.
One API. Every channel.
