Overview

Courier is a notification infrastructure platform founded in 2019 by CEO Troy Goode and headquartered in San Francisco, California. It emerged from Y Combinator's Summer 2019 batch and later raised a $35 million funding round, growing to an estimated 51-200 employees.

The company's core product lets developers trigger multichannel notifications, spanning email, SMS, push, in-app, and chat, through a single API call, while a visual studio lets both engineers and non-technical teammates design templates and notification flows without redeploying application code.

Key Features

Courier's platform includes Journeys for multi-step notification flows, broadcasts for one-to-many messaging, an MCP server, a CLI, and SDKs for popular languages. It centralizes routing logic and user notification preferences so a single API call can determine the right channel to use.

Enterprise-oriented capabilities include role-based access control, observability integrations, EU data residency, and AI-assisted features such as automated translations and an AI agent notification node available on paid tiers.

Pricing

Courier prices based on notification volume rather than team size or number of channels. The free Developer tier covers up to 10,000 sends per month; the Business tier is pay-as-you-go at $0.005 per send with AI features and chat support added; and Enterprise offers custom volume-discounted pricing with SLAs, RBAC, and dedicated support.
