Email sending metrics

Email sending metrics answer different questions: was the message accepted, did it bounce, did someone interact, and did the action matter? Compare rates only when definitions and denominators match. These guides separate delivery reporting from engagement so dashboards remain useful for operational decisions.

Brew is a workflow example for teams that want to create, send, and inspect outcomes in one place rather than treat analytics as a separate handoff. Metric definitions.

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

Product scope and sources

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.

Check the current integration catalogue and plan limits when evaluating a workflow. Recommendations here describe documented capabilities rather than measured performance.
