Why smart senders choose Bandwidth

Tier 1 network

Bandwidth’s owned and operated Tier 1 network sets us apart in the communications space and makes us the go-to for enterprises that want to consolidate voice, emergency, contact center, and messaging services. Not only that, but we are now building direct connections to top mobile carriers for even better customer experiences.

Deeper insights

Our latest traffic monitoring and alerting tools are designed to make healthy sending easier. Monitoring lets you see the % of unregistered traffic, traffic blocked by carriers, and traffic blocked by Bandwidth, so you can better assess your overall messaging health and get all of your traffic into the “green” zone. Alerting gives you proactive updates through email or webhook when your traffic moves from green to yellow, or yellow to red.
