Load-balanced delivery
No single provider carries all your traffic.
Your messages are shared across multiple delivery providers, so one provider’s bad day doesn’t hold up everything you send.
Reliability How Notify.lk delivers your SMS
SMS delivery that doesn’t depend on one provider
We share your messages across multiple delivery providers. If one goes down, the others take over its share automatically, and your customers still see your Sender ID.
What you get
Built to keep your messages moving
OTPs, order updates, reminders and campaigns go out through the same routing, whether you send from the API or the dashboard.
Automatic failover
If one goes down, the others take over.
Its share moves to the other providers automatically. No settings, no support ticket.
Delivery providersAutomatic failover
- Provider ADelivering, plus B’s share
- Provider BDown, its traffic moved
- Provider CDelivering, plus B’s share
Same Sender ID
Your name, whichever route delivers it.
We register Sender IDs with more than one provider, so a change of route doesn’t change what your customers see.
The platform
An API built to stay up.
Our API runs on Amazon Web Services, in a load-balanced Kubernetes cluster on a private network, and we monitor it around the clock.
- Load-balanced Requests are spread across the cluster
- Private network Servers sit behind the load balancer, out of public reach
- Monitored 24/7 We continually watch for issues
For developers
Nothing to change in your integration
We choose the route after your message reaches us. You keep the same API call, the same plugins and the same dashboard, and failover just works.
- The same endpoint and parameters
- The same Sender ID on every route
- Nothing to switch on
# The same call you make today.

What happens if a delivery provider goes down?
Its share of your messages moves to our other providers automatically. You don’t need to do anything, and there’s nothing to change in your integration.
Will my customers see a different Sender ID?
No. We register Sender IDs with more than one provider, so your customers see the same name whichever provider delivers the message.
Is there anything to switch on?
No. Load-balanced delivery and automatic failover are part of how Notify.lk sends SMS, so they already work on your account.
Do I need to change my integration?
No. Keep using the same API, plugins and dashboard. We choose the route after your message reaches us.
Where can I check your uptime?
On our public status page, status.notify.lk. It shows the current status of our services and their uptime history.
