courier.com
Courier is a notification infrastructure service for sending product-to-user messages across email, SMS, push, chat, and in-app channels. It also provides tools for managing user profiles, preferences, templates, automations, and multi-tenant messaging.
Courier exposes a REST API at https://api.courier.com, an MCP server at https://mcp.courier.com, and a `courier` CLI; all use a Courier API key, and Courier can also issue scoped JWTs for client-side Inbox/auth flows.

Sign up or log in to Courier, then open Settings > API Keys and create or copy an API key. Courier documents that Test and Production use separate keys. Use the key as Authorization: Bearer <API_KEY> for the REST API, set COURIER_API_KEY for the CLI, or pass it to MCP clients in the api_key header.
