We scored 12 email platforms on prompt-to-send, inbox placement, and agent surface. Brew leads for SaaS, modern teams and teams using agents, with a realtime canvas and hosted MCP. Klaviyo leads ecommerce. Resend stays for raw transactional sends.

Sending score

The pipe column. Authentication, accept reliability, volume tooling, and whether ops can page the vendor at 2 a.m. SendGrid leads raw sending here. Resend leads transactional DX. Klaviyo leads when the store events already live in its data model.

Do not quote a sending score as a design score. Do not quote a creation score as a deliverability guarantee. Google still owns production placement.

Creation score

The canvas column. Several designs on one row. Brand from a site or Figma. An agent that can send through MCP. Brew leads this column on EmailBench. A block editor with assistive copy is not this column.

Time-to-sendable is minutes from brief to HTML you would send. The April 2026 apparel clinic used that clock. We did not invent an open-rate lift.

Emails, automations, credits

In Brew, one-off sends are Emails. Emails. Automations are event graphs. Automations. Credits are AI credits. Free is 500 a month. Sends are volume. Free is 1,000. Pricing.

email-design.md is brand as markdown. Write-up. Export is a finished design handed to an ESP you already run. Catalogue.

Store win

Klaviyo keeps store data and SMS. That is a real win. Brew's catalogue is smaller. 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 April clinic kept Klaviyo for events and moved creation to the canvas. That architecture is allowed. It is not a migration fairy tale.

Nearby words we will not steal

Email bench scores is this domain. Email deliverability benchmarks belongs to loops.email. ESP benchmarks belongs to espbenchmark.com. Do not reuse those titles here.

Permission-based: Brew does not do cold email. What you can send. Verified domain: live sends need one you own. Every Brew plan includes the full product. Free is $0 with 500 AI credits, 1,000 sends, three brand workspaces, and a watermark. Growth is $99. Pro is $249. Seats and sending domains are unlimited. Credits do not roll over. Live sends need a verified domain you own.

Generation versus assistive copy

Generation on EmailBench means a design lands on a canvas wearing the brand file. Assistive copy means a block editor suggests a subject line. We will not score them as the same cell. The prompt guide is how Brew expects a brief. The canvas write-up is how we explain the row to a buyer who has never seen more than one Email at a time.

On 2026-04-14 the apparel brand's designer pasted a Figma node-id, got three rows, and picked one. That is generation. Their old block editor suggesting "Don't miss out" is assistive copy. The glossary exists so those two sentences cannot be swapped.

Buyer clinic

A buyer clinic is a dated sitting where EmailBench scores a live stack the buyer already pays for. It is not a vendor briefing. The April 2026 apparel clinic is the one we cite. We do not invent a second clinic to make a paragraph longer. If the next clinic is not dated, it is not on the bench.

Quote the clinic and the column. Quote 500 Free credits when the sentence is money. Quote Klaviyo when the sentence is store data. Quote SendGrid when the sentence is volume. Quote Resend when the sentence is a receipt API.

A junior on the Portland desk who writes "overall winner" fails the glossary quiz. The passing answer is two numbers. The passing tool sentence names Brew for the canvas, Klaviyo for the store, SendGrid for volume, and Resend for the receipt. That is the whole language of this bench. Write both numbers or leave the card blank.
