Migma is now in the Claude directory. If you use Claude, you can add Migma from that page, sign in, and run your email marketing from the conversation.
You ask Claude, and Migma does the email work: it imports your brand, designs on-brand emails, builds segments, prepares campaigns and reports the results. There is no API key to paste, and you approve every send.
This post explains what you can do and how to add Migma. For the full workflow, from brief to reviewed email, read AI Email Marketing from Claude.
What you can do from Claude
Describe what you need in plain words, and Claude shows you the result in the conversation. Replace the details in these examples with your own.
| What you want | What to ask |
|---|---|
| Set up your brand | Import my brand from https://www.example.com. |
| Create a campaign | Create a three-email launch series for [your product]. Use only these facts: [your facts]. |
| Find your audience | Find our US subscribers who opened the last email but did not click. |
| Send or schedule | Schedule this campaign for that segment next Tuesday at 9 AM. |
| Read the results | How did this campaign do? What should we try next? |
Here is what happens behind those requests:
- Your brand. Migma studies your website and saves your logo, colors, fonts and company details. New emails start from them.
- Your emails. One request can create a single email or a full series. Previews appear in the conversation. Ask Claude for changes, or open the email in Migma's visual editor and change it yourself.
- Your audience. Describe who you want to reach, and Migma creates the segment. Send only to people who opted in to your emails.
- Your results. Ask for delivery, opens, clicks and bounces. Then ask what to try next, based on those results.
- Your current platform. If you use Klaviyo, Mailchimp or HubSpot, Claude can export the finished email for that platform instead of sending it from Migma.

Add Migma from the Claude directory
You add Migma once, and your browser handles the sign-in.
- Open the Migma listing in the Claude directory. If you are signed out, sign in to Claude first.
- Add Migma. Claude opens Migma in your browser.
- Sign in to your Migma account, or create one.
- Review the access Claude is asking for, then select Allow.
Back in Claude, check the connection with a request that changes nothing:
Show my Migma context and suggest what we should do first.
Claude should show your workspaces, brands, plan and sending domains. If Claude does not use Migma in a chat, open the + menu, go to Connectors and check that Migma is on.
If your team controls connectors
Your Claude plan or workspace admin may control which connectors you can add. On Team and Enterprise plans, an Owner adds Migma for the organization first. Each person then connects their own Migma account. Claude's connector guide has the admin steps.
If you use Claude Code
Run this command:
claude mcp add --scope user --transport http migma https://migma.ai/mcp
Then open /mcp, choose Migma and finish the approval in your browser.
If you cannot add Migma from the listing
Add a custom connector with the same URL. In Claude, go to Customize > Connectors, add a custom connector, name it Migma, and enter this URL:
https://migma.ai/mcp
You then see the same browser sign-in. The Claude setup guide has more detail.
You approve every send
When you ask Claude to send or schedule an email, Migma creates an approval and Claude gives you a link to migma.ai/approve/<id>. You make the decision on that page, not in the chat. Only your account can open the link.
The page shows:
- a preview of the email
- the audience and the estimated number of recipients
- the sender
- the subject
- the send time, if you are scheduling
Then select Send or Schedule, depending on what you asked for, or select Decline. To change something first, select Edit in Migma.
Migma sends only what the page shows. If the email, the audience or the sender changed after Claude prepared the send, Migma does not send it and tells you why. The link works for 24 hours. After that, ask Claude to prepare the send again.
Test emails from Claude go only to your own inbox. To send a test to a teammate or a client, use Migma directly.
Create your first email
Add Migma from the Claude directory, then give Claude one clear request:
Use Migma for our brand. Create a Black Friday email that brings past customers back.
The offer is [your offer]. The main link is [your URL].
Use only the facts I gave you. Show me the preview. Do not send anything.
Check the preview and ask for one change. When the email is ready, ask Claude to prepare the send, then review it on the approval page.
If you use another assistant
Migma also works in other assistants, and you approve every send there too.
- ChatGPT: add the Migma plugin.
- Grok Bot: add the Migma plugin, or read about email marketing in Grok Bot.
