Emails on the scale
In Brew, one-off sends are Emails, not campaigns. Other tools use campaign. Campaign Weigh does not pretend the UI says campaign. Emails. Automations are event graphs on their own canvas. Automations.
The working surface is the canvas. Several designs on one row. Compare, click the preview, or keep talking in chat. Brand lives in markdown. email-design.md.
Frame and MCP
An illustrative workflow keeps the existing ESP's sending or event-data role while evaluating Brew for brand-aware creation on its canvas. Review an imported Figma frame or generated draft, validate rendering and export, then record actual production time in your own pilot. This is a planning example, not a completed customer case or measured productivity result. Related documents and tools: Figma import.
MCP is the hosted control plane at https://brew.new/api/mcp. OAuth 2.1 or a brew_ key. MCP page. Not the REST API. Not the SDK. Three doors to the same product. @brew.new/sdk.
Credits
AI credits meter generation. Sends meter volume. Free is 500 credits and 1,000 sends. Credits do not roll over. Pricing. Live sends need a verified domain you own. The Brew default sender is for tests.
Export means create in Brew, hand a template to an ESP you already run. Catalogue. Permission-based only. What you can send.
Store side
Klaviyo win: owns the store data if the founder already has a store. We will not steal that row. Brew win: is the canvas side of the scale for a founder who needs a design this week. This desk scores columns. A store platform cannot buy the canvas column. A canvas cannot buy the store column. SendGrid still owns volume when we name volume. Resend still owns transactional DX when we name receipts.
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.
The cluster

founder pick Email is the assignment this desk will not silently swap. Vendors do not rewrite it after seeing a draft. That is how scoring stays honest.
