# Brew

> Brew is an AI-native email service provider (ESP): you describe an email, automation, or segment in plain English and Brew generates the on-brand email, sends it from your own verified domain, and reports on it — with a Public REST API, a TypeScript SDK, and a hosted MCP server so AI agents can drive the whole lifecycle.

- **What it is:** a full email service provider — Brew stores the contacts, owns the sending infrastructure, and authenticates your domain with SPF, DKIM and DMARC. It is not a layer on top of another ESP.
- **How you use it:** describe the email, automation, or audience segment in natural language. Brew learns your brand (voice, palette, typography, logos, imagery) from your website and applies it to everything it generates.
- **What you can build:** one-off emails (what other tools call campaigns), event-driven automation graphs with branching and delays, and transactional email — all from the same brand system.
- **Who it is for:** marketing and growth teams who want to ship faster, and developers or AI agents that need email as an API primitive.
- **What is unusual about it:** the same capabilities are exposed on four surfaces with parity — the web app, the Public API v1, the `@brew.new/sdk` TypeScript package, and a hosted MCP server. Anything you can do by hand, an agent can do over MCP.
- **Deliverability:** permission-based sending only, with domain verification, suppression lists, bounce handling, gradual-send warmup for new domains, and inbox-placement testing.

## For AI agents — the Brew MCP server

The fastest way for an agent to use Brew. One hosted MCP endpoint gives
an assistant the whole lifecycle: learn a brand, generate and edit email
designs, build automations, segment audiences, send or schedule, and read
analytics back. Everything is scoped to a single brand chosen at connect
time. Compose it with a CRM or enrichment MCP (Clay, Attio) for
personalized segments.

- Connection URL: `https://brew.new/api/mcp`
- Auth: OAuth 2.1 with Dynamic Client Registration + PKCE, or a brand-scoped Brew API key

## For developers — Public API v1

audiences, contacts, automations, triggers, domains and analytics.

## Integrations

Brew connects to 19 tools, in two directions. Data-in providers feed
Brew — firing automations from product events (a signup, a payment, a
subscription change) or pulling designs and responses in. Data-out
providers receive finished email designs, so you can keep sending from an
ESP you already run.
