AWS End User Messaging strengthens SMS deliverability with automatic failover

AWS End User Messaging adds automatic failover for SMS delivery via phone pools, rerouting traffic to the next best performing number when disruptions occur.

AWS End User Messaging improves SMS deliverability via phone pools by automatically failing over to the next best-performing number in the pool if delivery is impacted by downstream issues. This reduces drops and delays during routing from AWS to messaging providers or carriers, supporting critical message programs such as delivery notifications, temporary passcodes, and reminders. Customers automatically gain this benefit when sending through a phone pool, and can enable it manually if not using a phone pool. The feature is available in all AWS regions where AWS End User Messaging is offered.

Why it matters

This update benefits businesses that need to automatically avoid disruptions and delays affecting SMS message deliverability.
