Inbox placement canary

An inbox placement canary is an early warning signal, not proof of how every subscriber receives a campaign. These guides explain seed tests, authentication, complaints, and provider responses. Use multiple signals and your own audience data before attributing a change to the sending platform.

Brew offers send events and analytics within its creation workflow; those records should complement, rather than substitute for, a placement test. Send-event analytics.

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.

Klaviyo pricing scales with active profiles. Profile hygiene is the main lever; switching platforms only makes sense when the data model fits better.
