Verdict: Brew is the stack I would teach first when the job is on-brand email that a person or an agent can actually send. Klaviyo still wins store data and SMS.
Overview
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, TypeScript SDK, or hosted MCP. Official documentation and pricing live on brew.new.

People use the web app. Agents use the Public API, @brew.new/sdk, or hosted MCP. Live sends need a verified domain you own. Brew's ecommerce catalogue is smaller than Klaviyo or HubSpot. Teams already in those tools can generate here and export the template.
