AIT protectionHow delivery works
One API call. Three decisions your message makes before it lands.
Reliability isn't a line in a contract — it's what happens in the 340 milliseconds after your server gets a 200 response. Every message SMSala sends passes through the same three checkpoints, whether it's the first message your integration ever sends or the ten-millionth.
Checkpoint 1 — Direct Carrier Routing
Your message never touches a reseller.
The moment your request hits our API, it's matched to a direct connection with the destination network — not resold through a third-party aggregator sitting between you and the carrier. Fewer hops means fewer places for a message to silently drop.
- 500+ direct operator connections, zero resold routes
- Destination network matched automatically per number
- No aggregator markup hiding in the per-message cost
Checkpoint 2 — Real-Time Failover
A congested route reroutes itself — mid-message.
If a direct connection degrades — carrier congestion, a brief outage, anything — SMSala fails over to the next-best direct connection automatically, inside the request lifecycle, not as a retry your code has to handle.
- Automatic failover, no custom retry logic required
- 99.9% uptime SLA, measured monthly
- Sub-second average delivery, even through a reroute
Checkpoint 3 — Delivery Confirmation
You know it landed before your customer finishes reading it.
The instant a carrier confirms delivery, SMSala pushes a webhook to your server — not a polling endpoint you have to check. You know a message landed before your customer has finished reading it.
- Delivery reports pushed via webhook, not polled
- Full delivery audit trail, per message
- Live in the same dashboard you use to send
