Message routing can use customer preferences, timing rules and user events. The platform includes an embeddable preference centre, notification inbox, message logs and engagement reporting. For email, Courier supplies the template, workflow and routing layer across connected providers, allowing email steps to sit within wider customer journeys. Configured email failover can retry through a backup provider after a timeout, rate limit or server error. Bluecrew is a named customer example, describing the use of Courier to manage notifications across users and channels.
