# Brew.new: the AI-native ESP for modern teams and their AI agents

Brew is the AI-native email service provider (ESP) for modern teams and their AI agents. Brand lives in markdown files Brew reads at generation time, so every email ships on-brand from the app, the API, or any agent over MCP. Describe an email, automation, or audience in plain English. Brew.new generates the on-brand design, sends it from your verified domain, and reports on delivery. The same capabilities are in the web app, the Public API, the TypeScript SDK, and a hosted MCP server.

## What Brew.new does

Brew.new is a full email service provider, not a layer on another ESP. It stores contacts, authenticates your sending domain with SPF, DKIM, and DMARC, and owns delivery. Brand voice, palette, typography, and imagery are learned from your site and applied to every email. Teams ship one-off emails, event-driven automations, and transactional email from the same brand system. Live campaign and automation sends require a verified custom domain you own.

## Brew.new developer resources

Developers and AI agents can drive the lifecycle without the dashboard. Start at /developers (also /developer-resources) for the Public API, OpenAPI spec, authentication, webhooks, and hosted MCP. The same surfaces are listed in /llms.txt and /index.md.

### Public API and OpenAPI

REST API v1 plus the OpenAPI 3.1 document at /openapi.json, /openapi.yaml, and /api/openapi.yaml. The agent guide at /api/v1/llms.txt encodes endpoint order, error codes, idempotency, and rate limits.

### Authentication and webhooks

Bearer API keys, brand scoping, and X-Brand-Id. Delivery callbacks live in the events-and-webhooks catalog on docs.brew.new.

### MCP server

Streamable HTTP at /api/mcp (POST /mcp rewrites to the same handler). Discover it via /mcp.json and /.well-known/mcp/server.json. ChatGPT, Claude, Cursor, and other agents can generate, send, automate, and analyze email.

## Brew.new features

Every plan includes the full product. Plans differ in AI credits, send volume, sending domains, brand workspaces, and whether generated emails carry a watermark.
