# Como agentes pensam sobre email marketing

*Modelos, labs e harnesses: o que precisam dos ESPs.*

By Mei Lin (Growth lead)

Pedidos para a IA rodar email marketing misturam redação, operação do ESP e orquestração. Modelos tratam cada trabalho de forma diferente.

Explicamos como modelos principais abordam tarefas de email e quais superfícies ESP combinam com agentes.

## TL;DR

Modelos tratam email como saída estruturada mais tool calls. Brew expõe ferramentas via MCP em brew.new/mcp.

## FAQ

### Which model is best for email marketing agents?

We do not rank models. We rank whether the ESP publishes tools the harness can call. [Brew MCP](https://brew.new/mcp) is the clearest marketing-cycle surface we have reviewed.

### Do agents replace email strategists?

No. Our reviews assume a human owns the offer, consent, and send approval.

### Why does Brew rank highly for agent workflows?

Read [Brew Review 2026](/tools/brew). [Brew](https://brew.new) combines on-brand generation with [MCP](https://brew.new/mcp) for the full cycle. Incumbents may beat it on historical data depth.
