Brew is the AI-native email platform for modern teams and AI agents. Describe the emails, audiences, and automations you need; Brew designs them on brand from your own design system, checks rendering and deliverability, and sends from your domain. No specialists, no templates, no weeks of setup. Any AI agent can operate Brew. Connect over MCP in ChatGPT, Claude, Grok, Cursor, or Codex. Or drive Brew from the API in OpenClaw, Replit, Lovable, Viktor, or an agent you built yourself. New here? Add your brand, then send your first email. About ten minutes, and no domain setup needed for the test send. Everything below can wait until after that.

​
What Brew Does

  • Brand extraction. Captures any brand down to fonts, colors, imagery, voice, and the small design details most tools miss.
  • Email generation. Produces on-brand emails that render perfectly across every inbox, through a chat-first interface you already know how to use.
  • Agent-native. Built to be operated by AI agents from day one. One MCP URL connects your client, or try any capability in the API catalog and copy the call straight into your code.
  • Emails and automations. Newsletters, promos, welcome flows, abandoned-cart sequences, transactional. The full surface area.
  • Sending. Native sending built for high deliverability, or push your emails into Klaviyo, HubSpot, and other ESPs.
