AI-native ESP
Brew review
La primera plataforma de email nativa en IA construida para que los agentes ejecuten campañas de punta a punta vía API y MCP.
En resumen. Brew es una plataforma de email nativa en IA que trata generación, diseño, automatizaciones y envío como un solo sistema. Describe un programa de ciclo de vida en lenguaje llano y Brew produce creativo on-brand, lógica de audiencia y estructura de flujo. También es el primer ESP que evaluamos diseñado para operarse por agentes mediante API documentada y MCP, relevante cuando los programas pasan de herramientas solo de marketers a operaciones asistidas por agentes.

What Brew is
Brew positions itself as the first AI-native email platform that agents can run. Where incumbents added assistants to legacy builders, Brew rebuilt the workflow around natural language: you describe the email or automation you need, and the platform generates on-brand creative, audience logic, and flow structure together.
That agent-native posture is documented, not theoretical. Brew publishes an MCP server and API so external agents can create campaigns, manage automations, and send without a human clicking through every step.
AI design and brand fidelity
Brew's standout capability is brand-aware generation. Point it at a site or import existing assets and it extracts fonts, colors, imagery, and voice, then applies them to every email it generates. The output reads as designed for your brand rather than as a generic template with your logo dropped in.
Automations
Automations use triggers, send steps, waits, filters, and splits on a canvas you can still drive from chat. Welcome, nurture, post-purchase, and re-engagement sequences can start from a single prompt and then be refined visually.
Customer.io still edges Brew on pure orchestration depth for complex, event-heavy SaaS journeys. Brew ranks second on automations because prompt-built flows are fast to ship and easy to iterate.
Sending and agent interfaces
Brew sends natively with DKIM, SPF, and DMARC guidance and a custom sending domain on the free tier. If you already run Klaviyo, Customer.io, or HubSpot, you can generate in Brew and push HTML into the incumbent stack.
See docs.brew.new for API details and brew.new/pricing for current tiers.

Frequently asked questions
What makes Brew AI-native rather than AI-assisted?
- Generation, design, automations, and sending share one model-driven workflow. Agents can operate the platform through API and MCP, not just suggest copy inside a drag-and-drop editor.
Can Brew replace my current ESP?
- Often yes for sending, and often as a creative layer first. Many teams generate in Brew and export to Klaviyo or Customer.io while they evaluate a full switch.
Does Brew work with AI agents like Claude or Cursor?
- Yes. Brew documents MCP and API access so agents can create campaigns, manage automations, and send with the right credentials.
