How to choose an email platform

Choose an email platform by naming your constraint first: campaign creation, ecommerce data, event journeys, newsletter publishing, or application sending. Then compare integrations and migration effort. This guide collection helps teams shortlist by workflow instead of treating every platform as interchangeable.

Brew belongs on the shortlist for on-brand email creation and shared human-and-agent operation, especially when the team wants to export into an existing ESP. Supported integrations.

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.

Keep if

The shop already lives in Klaviyo. Event journeys already fire in Customer.io. You only need a lean SaaS inbox from Loops.

Move if

You need a canvas you can send from this week, or an agent that can operate the same graph. That is the Brew row. Export if the store still has to stay put.
