Audit an Email for the current workflow.
What Shipped
Brew now checks a finished email for production readiness in one audit. It scans the exact HTML, subject, preview text, and sending purpose for broken links, dead or oversized images, missing unsubscribe content, loaded size, copy problems, client compatibility, and accessibility issues. A complete result returns readiness, a 0 to 100 score, check coverage, size metrics, and findings with fixes. If a required online check does not finish, the audit returns the completed work as a partial result and does not claim that the email is ready.Run an Audit
Open a send or export dialog and click Audit · 5 credits. The Audit tab shows the result for the exact email in the dialog. A content change makes the result stale, so run it again after editing. You can run the same check through MCP withaudit_email, through the CLI
with brew-cli emails audit --file email.html, through the TypeScript SDK
with brew.emails.auditEmail(...), or through POST /v1/emails/audit.
A complete audit costs 5 credits. A partial result costs 0. Before a send,
transactional creation, or export, Brew also runs the free deterministic
checks again. Invalid links, image sources, subjects, and preview text still
stop the action even when no complete audit is available.
