| What it costs | Claude alone: Free with one custom connector; Pro $20 a month | Claude + Brew: Brew from $99/month: 10,000 AI credits and 50,000 sends |
Claude Free includes one custom connector. Pro is $20 a month, or $17 billed yearly, and Max starts at $100.
Brew is billed on emails sent and AI credits, with unlimited contacts on every plan: a free trial with 500 AI credits and 1,000 sends, then Growth at $99/month for 10,000 AI credits and 50,000 sends.
Claude connects to remote MCP servers on every plan, in claude.ai, Claude Desktop and Cowork. Free allows one custom connector.
Start a free trial, paste your website so Brew writes your brand files, and connect your sending domain.
In Claude, go to Customize → Connectors → Add custom connector. On Team and Enterprise, an Owner adds it under Organization settings first.
Enter https://brew.new/api/mcp, choose to sign in now, click Add and sign in to Brew.
Describe the email or flow in a chat. Claude asks before it uses Brew’s tools, and Brew asks you to confirm before anything sends.
Connect Claude, ChatGPT, Cursor or Grok over MCP and your agent gets every Brew tool. It designs emails from your brand, builds audiences, runs automations and schedules sends. OAuth and organization-scoped MCP connections ask you to confirm live sends and launches. Brand-scoped API keys can execute permitted calls without the MCP confirmation step.
Paste your website and Brew writes your brand into two files your agent reads for every email. Describe the email and it appears on the canvas, ready to edit by hand or in chat.

Partly. Claude can plan campaigns, write copy and draft emails in your own Gmail. On its own it does not design a finished, on-brand email, hold your contacts, send from your domain or run automations.
Not marketing email. The Gmail connector can send single emails from your own mailbox with your approval, but Claude has no contact list, unsubscribes or sending domain.
Connected to Brew, Claude sends campaigns from your own domain to your audiences, with unsubscribes handled, after you approve.

Any plan. Free allows one custom connector, which can be Brew; Pro, Max, Team and Enterprise allow more. On Team and Enterprise, an Owner adds the connector first.
Claude writes good copy, but on its own it does not design the email from your brand. Brew does: it writes your brand into files your agent reads for every email, then designs the layout, copy and images and tests how it renders.
No. Over OAuth, Brew asks you to confirm before anything is sent or goes live, so the assistant drafts and you approve.
