Bulk SMS & messaging APIs

Messages that arrive, with delivery reports you can trust.

/ The problem

SMS remains the only channel that reaches every phone on the network — no app install, no data bundle, no smartphone required. But bulk messaging done casually gets throttled, filtered, or silently dropped, and most senders never find out because they never read their delivery reports.

Sender ID registration, per-network routing quirks, and opt-out compliance are operational problems, not code problems. They need infrastructure that treats a delivery receipt as seriously as a bank treats a transaction.

/ How we deliver

We operate messaging infrastructure with direct aggregator and MNO connections, per-network routing, and automatic retry on temporary failures. Every message has a tracked lifecycle from submission to handset delivery receipt.

You get both an API for transactional messages — OTPs, alerts, receipts — and campaign tooling for scheduled broadcasts with contact-list management, templating, and opt-out handling built in.

/ What we build with it

OTPs & security alerts

Time-critical messages on dedicated transactional routes, never queued behind a marketing blast.

Statements & receipts

Automated notifications fired from your systems by API — payment received, order shipped, loan due.

Campaign broadcasts

Scheduled sends with templates, contact lists, and opt-out handling that keeps you compliant.

Two-way messaging

Surveys, confirmations, and keyword-routed inboxes delivered to your backend by webhook.

/ How delivery runs

  1. 1

    Sender ID registration

    We register your alphanumeric sender name with each network — the slowest step, so it starts first.

  2. 2

    API integration

    Your systems connect to the messaging API; templates and contact lists are set up alongside.

  3. 3

    Route testing

    Test sends across every network verify delivery, latency, and report accuracy before volume ramps.

  4. 4

    Scale & report

    Throughput is raised to plan, and delivery dashboards plus monthly reports go live.

/ Common questions

How fast is delivery at volume?

Throughput is provisioned per client and scales to millions of messages per day; transactional messages are prioritised on dedicated routes so OTPs are never queued behind campaigns.

Can we use our own sender name?

Yes. We register your alphanumeric sender ID with each network on your behalf — allow a few working days per network for approval.

Do you support two-way SMS?

Yes, via dedicated shortcodes or shared long codes with keyword routing, delivered to your systems by webhook.
