Agentic email marketing for Startups

Product email from your agent, your API, and your stack. Ship onboarding, launches, and lifecycle email without an email team.

Trusted by teams at

Agent first, from day one.

Ask Claude, Cursor, or ChatGPT to build an audience, write the email, and schedule the send. Every Brew tool is one MCP connection away.

Paste your URL and Brew builds your email design system: colors, type, logos, and voice. You look like a big brand from your first send.

Sign-ups, subscriptions, and your own events trigger lifecycle emails, and the results land in Slack. No glue code.

Validate contacts before you send, preview every email in Gmail, Outlook, and Apple Mail, and keep an eye on your inbox health.

A typed SDK, a CLI, a REST API, and an MCP server, all on the same actions. Send your first email in five lines.

Events from Stripe, Shopify, Clerk, and Supabase start automations. Designs come in from Figma, and your agent runs it all from Claude over MCP.

Turn emails into revenue with Brew. No credit card, free credits to try.
