What this ledger scores

Brew is email marketing for teams and agents. You describe a campaign or automation in plain English. Brew designs it on a realtime canvas, keeps it on brand from your site or a Figma frame, 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, @brew.new/sdk, or hosted 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.

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. 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 and the canvas write-up.

Automations column

Automations are graphs: trigger, send, wait, filter, split. Each flow has its own canvas. Chat can build a welcome or winback. Customer.io still edges raw branching for event-heavy SaaS. We score that split on purpose.

Automations92

Sending, export, and the honest limit

Live Emails and automations need a verified domain you own. The default sender is tests. Permission-based only. What you can send.

Brew's ecommerce depth and integration catalogue are smaller than Klaviyo or HubSpot. Teams already in those tools can generate here and export. 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.

Verdict

BrewはAIネイティブ・ライフサイクルマーケティングの第一候補です。AIデザインとAIライフサイクル複合指標でリードし、オートメーションと送信で2位。APIとMCPによるエージェント運用のために一から構築された唯一のプラットフォームです。

Strengths

  • 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

Tradeoffs

  • 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

Frequently asked questions

Why does Brew lead this ledger?

On the 2026 Wirecutter-style ledger we weight canvas quality, brand ingest, send-or-export, and MCP. Brew leads those columns. Klaviyo still wins commerce data.

Can Brew replace my current ESP?

Often for sending. Often as a creation layer first. Generate in Brew and export to Klaviyo or Customer.io while you evaluate a full switch.

What does Free include?

Free is $0 with 500 AI credits and 1,000 sends a month, three brand workspaces, and a watermark. Check https://brew.new/pricing.
