Your AI assistant can now run your email marketing

If you run email, you've probably noticed how much of your day now happens inside an AI assistant. You're drafting copy in Claude, brainstorming subject lines in ChatGPT, maybe asking it to pull together a quick report. The work keeps drifting into the chat window.

So we made Brew work there too.

Brew now speaks MCP, the Model Context Protocol. In plain terms, that means your AI assistant can do real work in Brew instead of just talking about it. Connect it once and you can ask your assistant to write a campaign, send it to the right people, set up an automation, or pull last week's numbers. It's the same brand, the same lists, and the same emails you'd build in the app. You just don't have to be the one clicking around to make it happen.

What it can actually do

This isn't a chatbot handing you advice. It's your assistant doing the job. Once Brew is connected, you can ask it to:

• Write on-brand emails from a quick description, then keep tweaking until they're right
• Send campaigns and test sends through your verified domain, now or scheduled for later
• Build automations like a welcome series or a win-back flow, and turn them on
• Add contacts, manage custom fields, and build a segment just by describing who you want to reach
• Pull the numbers that actually matter, like opens, clicks, bounces, and how your automations are doing
• Generate on-brand images and GIFs for your emails

It all stays on-brand because it's running on the same Brew that already learned your colors, fonts, and voice. An email your assistant sends looks exactly like one you'd build by hand, and it still goes out through your verified domain and lands in the same reports you already check.

One connection, and your assistant gets the whole Brew toolkit.

Getting connected

It takes about a minute. Grab your API key from Settings, then API in the app, drop the connection into your assistant, and you're set.

{
  "mcpServers": {
    "brew": {
      "url": "https://brew.new/api/mcp",
      "headers": { "Authorization": "Bearer brew_YOUR_API_KEY" }
    }
  }
}

That's the whole setup. It works with Claude, Cursor, and pretty much any assistant that supports MCP. Your key already knows which brand you're in, so there's nothing else to wire up.

How marketers are using it

The most common thing we see is people running campaigns in conversation. You type something like "write a launch email for the new feature, match our brand, and schedule it for Tuesday at 9am to everyone on a trial." Your assistant drafts it in Brew, shows you a preview, and schedules the send. You never leave the chat.

The next step is letting it run on its own. Some teams hand the keys to an AI "employee" like Viktor, which lives in Slack and does real work, and give it a standing job: watch for new signups, drop them into the welcome series, and post the open rates to the channel every Monday. Brew handles the email, Viktor keeps an eye on things, and the team just reviews what came back.

You're still the one calling the shots on strategy and creative. You're just not stuck doing the repetitive parts anymore.

Even better with your CRM

Brew is good at one thing: being the memory and the muscle behind your email program. It gets a lot more useful when your assistant runs it next to the other tools you already have.

Connect Brew to a CRM or enrichment tool like Clay or Attio, and your assistant can handle the whole loop without you copying anything between tabs. It pulls fresh data on a contact, saves that context to their Brew profile, builds a segment around it, sends a campaign written for that group, then checks how it did and adjusts for next time. That's real personalization, and you didn't have to babysit any of it.

Your assistant runs Brew next to your CRM: enrich, segment, design, send, measure, repeat.

Give it a try

The Brew MCP is live today. Grab a key in Settings, then API, connect it to your assistant, and ask it to send your next campaign. I think you'll be surprised how much of your week it can take off your plate.
