# What is smart routing in SMS?

> Smart routing is the logic a messaging platform uses to choose the best path for each message in real time — selecting among operator routes by quality, cost, and destination, and re-routing automatically when a path degrades. It aims to maximize delivery and control cost without manual intervention, and is closely related to least-cost routing and automatic route failover.

## What it optimizes

For each message it weighs route quality, delivery history, and cost to the destination operator, picking the path most likely to deliver reliably at a sensible price. See /answers/what-is-lcr and /answers/sms-routing-lcr.

## Failover built in

When a route's delivery rate drops — a firewall block, an outage — smart routing shifts traffic to a healthy path automatically, protecting your delivery rate. See /answers/what-is-route-failover.

## Quality over pure cost

The smartest routing is not simply cheapest-first: a grey route with a low price but poor delivery raises cost per delivered message. Good routing weighs delivery, not just rate. See /answers/sms-deliverability-economics-2026.
