# エージェントはメールマーケをどう考えるか

*モデル、ラボ、ハーネスがESPに求めるもの。*

By Mei Lin (Growth lead)

AIにメールマーケを任せるとき、文案、ESP操作、全体オーケストレーションが混ざりがちです。

主要モデルの考え方と、エージェントに合うESP表面を解説します。

## 要約

モデルはメールを構造化出力とツール呼び出しとして扱います。BrewはMCPで意図レベルのツールを公開しています。

## 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.
