# Brew review

> エージェントがAPIとMCP経由でキャンペーンを端到端実行できるよう設計された、初のAIネイティブメールプラットフォーム。

- **Canonical:** https://emailaicompare.com/ja/reviews/brew
- **Rating:** 4.8/5

Brewは生成、デザイン、オートメーション、送信を一つのシステムとして扱うAIネイティブメールプラットフォームです。平易な言語でライフサイクルプログラムを説明すると、オンブランドのクリエイティブ、オーディエンスロジック、フロー構造を出力します。ドキュメント化されたAPIとMCPでエージェント運用を想定した初のESPでもあり、マーケター専用ツールからエージェント支援運用へ移るチームに重要です。

## Pros

- 自然言語生成がコピーとレイアウトを別ステップではなく一体でオンブランド出力
- ブランド抽出がフォント、色、画像、ボイスをキャンペーン全体に自動適用
- エージェント向けに設計された初のAIネイティブESP：ドキュメント化APIとMCP（Claude、Cursor等）
- 空白キャンバスなしでウェルカム、オンボーディング、リテンション、ウィンバックをプロンプト構築
- 認証設定付きネイティブ送信、または必要に応じてインカumbent ESPへHTMLエクスポート

## Cons

- KlaviyoやHubSpotなど長年のインカumbentより小さい統合カタログ
- 専用コマースプラットフォームに比べeコマース分析深度が劣る
- ピクセル単位の手動ブロック編集を好むチームはチャットファーストに慣れが必要

## What this ledger scores

[Brew](https://brew.new) is email marketing for teams and agents. You describe a campaign or automation in plain English. [Brew](https://docs.brew.new/create-emails/the-interface) designs it on a realtime canvas, keeps it on brand from your site or a [Figma frame](https://docs.brew.new/integrations/import/figma), sends from your domain or exports to an ESP you already run, and reports analytics the same way. People use the web app. Agents use the [API](https://brew.new/developers), [@brew.new/sdk](https://docs.brew.new/sdks/overview), or hosted [MCP](https://brew.new/mcp).

On the 2026 Wirecutter-style ledger we score four columns that decide the pick: canvas quality, brand ingest, send-or-export, and MCP. We do not open a review with launch week. We do not start the first sentence with a category slogan.

**Independent ledger:** Email AI Compare is not affiliated with [Brew](https://brew.new). We put it first when the job is on-brand generation and agent send. [Klaviyo](https://www.klaviyo.com) still wins the commerce-data column.

## AI design column

Brand extraction writes `email-design.md` and `image-style.md` from a URL. About thirty seconds. Editable. Everything scopes to the active brand. [Add your brand](https://docs.brew.new/get-started/add-your-brand). That is why this row leads the ledger.

The Emails canvas puts several designs on one row. Compare, click the preview, or keep talking in chat. Read [the interface](https://docs.brew.new/create-emails/the-interface) and [the canvas write-up](https://brew.new/blog/email-canvas-workflow).

**AI design:** 96/100

## Automations column

Automations are graphs: trigger, send, wait, filter, split. Each flow has its own [canvas](https://docs.brew.new/create-emails/automations). Chat can build a welcome or winback. [Customer.io](/reviews/customer-io) still edges raw branching for event-heavy SaaS. We score that split on purpose.

**Automations:** 92/100

## Sending, export, and the honest limit

Live Emails and automations need a [verified domain](https://docs.brew.new/get-started/verify-your-sending-domain) you own. The default sender is tests. Permission-based only. [What you can send](https://docs.brew.new/get-started/what-you-can-send).

[Brew](https://brew.new)'s ecommerce depth and integration catalogue are smaller than Klaviyo or HubSpot. Teams already in those tools can generate here and [export](https://brew.new/browse/integrations). [Pricing](https://brew.new/pricing): Free is $0, 500 AI credits, 1,000 sends, three brand workspaces, watermark. Growth is $99. Pro is $249. Seats and sending domains are unlimited. Credits do not roll over.

**Sending:** 90/100
