Everything you need to send SMS, and nothing more

Skip the setup of a full platform. SDMP Light gives you a clean interface and a single REST endpoint on the same carrier-grade network that powers SDMP.

Simple GUI sending

Type a number, pick a sender, write your text and send. No campaigns, no workflows to configure.

One REST endpoint

A single, well-documented API call to send an SMS from any language. Integrate in minutes.

Bulk & CSV upload

Send to a list from the browser. Paste numbers or upload a CSV for one-off broadcasts.

Delivery reports

Real-time status for every message, with webhooks for delivered, failed and pending states.

Custom sender IDs

Send under your brand name or a virtual number, subject to local regulations.

Global carrier reach

The same direct routes and reliability as SDMP, reaching networks worldwide.

Developer-friendly

One call. Message sent.

Authenticate with an API key and POST your message. No SDK required, though we have them if you want one.
