# Brew
> Brew is an AI-native email platform. Create on-brand emails, manage audiences, build automations, and send from verified domains in the app or through the API, SDK, and MCP server.
Marketing sends require permission from recipients and a verified sending domain. Integration setup and account administration can require the app; consult the endpoint or tool documentation for supported actions.
