DISCOVERED ON EARLYCOVEWhat is Courier?
Courier provides a platform for customer messaging across email, push, SMS and other channels. It is useful when a team wants a shared place to manage notification behavior rather than embedding all messaging decisions in application code. Test a journey with preferences, fallback behavior and a realistic failure. Its value depends on whether product and engineering teams can understand and maintain the communication rules together.
