SMS → RCS

Interactive messaging, not plain text

Go beyond 160 characters. Send verified, branded RCS with rich cards and one-tap replies — and fall back to SMS automatically on phones that don’t support it. Drag the slider to compare.

Developers

Integrate in an afternoon

One API and one provider for SMS, RCS, Email and Voice — with every message visible in the SendLab console, from accepted to delivered.

Read about the API →
import { SendLab } from "@sendlab/node";

const sendlab = new SendLab(process.env.SENDLAB_API_KEY);

await sendlab.messages.send({
  channel: "sms",
  to: "+61412345678",
  body: "Your booking is confirmed for Thu 10:30.",
  // your own ID — retrying with it never sends twice
  reference: "booking-4821",
});
Why SendLab

More than an API

01

Registration, handled

We register your senders and domains with you — and show every step until you’re live.

02

See every message

Accepted, delivered or failed, with the reason and the cost — not a guess.

03

A team beside you

Hands-on help to design, integrate and launch, and care that continues after.

04

Security by design

Scoped keys, consent and opt-outs enforced on every send, and a full audit trail.

How we work

We learn your business, build and launch with you, and stay involved as you grow — so the platform keeps delivering long after go-live.

  2. 02

    Build and launch

    We register your senders, integrate with you and test every path — including failures.
