# Brew

AI-native email platform that designs on-brand emails from a prompt, builds the audience and sends them.

Brew is an AI-native email platform for teams and AI agents. Describe an
email, audience or automation and Brew designs it on brand from your own
design system, checks rendering and deliverability, and sends it from your
domain. It is built for permission-based marketing and transactional email:
cold outreach to lists without opt-in is not permitted.

## Tools

- tool:brew/create-audience — Create an audience: Saves a live contact segment from a name and a set of field filters and returns the audience.
- tool:brew/create-audience-from-events — Create an audience from email events: Saves a frozen cohort of the contacts who opened, clicked or otherwise engaged in a time window or send, or with an exclude rule those who did not.
- tool:brew/fire-trigger-event — Fire a trigger event: Validates an event payload, upserts the contact it describes and starts one run of every published automation listening to that trigger.
- tool:brew/generate-email — Generate an email: Generates an on-brand email design from a plain-language prompt and returns its emailId, version id and HTML.
- tool:brew/send-email — Send an email: Sends an email design as a campaign to a saved audience or an inline recipient list through a verified domain, or one test copy with test set to true.
