Custom Environments for Safer Messaging Workflows

Courier now supports fully isolated custom environments, so teams can build and test customer messaging the same way they ship code. Create environments like dev, staging, QA, or production, configure separate provider integrations and API keys, and keep logs, metrics, templates, journeys, and subscription topics scoped to each environment.

When a message flow is ready, promote templates and dependencies between environments without affecting production. This gives teams safer testing, cleaner collaboration, and more control over how messaging changes move from idea to launch.
