What Shipped

Brew can now render any design across real email clients and devices (Gmail, Outlook, Apple Mail, iOS with dark-mode variants, and Yahoo) and returns a screenshot per client. Catch a broken Outlook table or a dark-mode contrast issue before the send goes out, not after.

​
How to Use It

1

Open a Design on the Canvas

Open any one-off or automation email. The Preview panel on the right now has an Inboxes tab.
2

Pick Your Clients

Choose a default spread (Gmail + Outlook + Apple Mail + iOS) or select specific clients, including OS + version + light/dark mode combinations.
3

Review the Results

Screenshots come back per client, rehosted on the Brew CDN. Slow clients show as Pending. Click Retry to fetch just those.

​
From the API

The same feature is available at POST /v1/emails/{emailId}/client-previews and as brew.emails.previewClients(...) in the TypeScript SDK. See the API Reference for the full client catalogue.
