Connect Claude & ChatGPT to Mailmojo

Ask your AI how your last newsletter did, who signed up this week, or to draft the next one in Mailmojo. It can search contacts, add and unsubscribe subscribers, create and update lists and newsletters, and read forms, templates and automations. Sending to a whole list is a separate tool you can keep off or put behind approval.

It looks up the list and adds the address as a subscriber on it.

Set up in three steps

1
Pick the app
Create a free PipMCP account and choose Mailmojo from the app list.
2
Paste your key
Mailmojo does not offer self-service API clients yet. Contact Mailmojo support and ask for an API client with https://pipmcp.com/oauth/callback as the redirect URI. When it is set up, open Min konto › API-tilgang in Mailmojo, copy the client ID and client secret, paste them into PipMCP and click Connect to approve access. This is an OAuth connection, so it needs the PipMCP Pro plan.
3
Add the link to your AI
You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:
1. Click your name, then Settings › Connectors › Add custom connector.
2. Paste your link as the Remote MCP server URL.
3. Switch it on from the + menu in a chat.

Questions

What can the AI do in Mailmojo?

It can read your account, lists, subscribers, contacts, custom fields, newsletters, forms, templates, automations and subscriber statistics. It can create and update lists, contacts and draft newsletters, add and unsubscribe subscribers, send test copies, send or schedule a newsletter and cancel a scheduled one.

Does the AI see my Mailmojo credentials?

No. Your Mailmojo credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with lookups only. Sending a newsletter reaches real subscribers and cannot be recalled, and a test send also sends real email, so those tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and add your PipMCP link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

Mailmojo connects with OAuth, and OAuth connections need the PipMCP Pro plan or above. PipMCP also has a free plan with no credit card, but it does not include this connection. Paid plans bill per completed task. You also need your own Mailmojo account.

Why do I have to contact Mailmojo support first?

Mailmojo does not let you create API clients yourself yet. Support sets one up for you with PipMCP's redirect URI, and you then find the client ID and client secret under Min konto › API-tilgang. After that you sign in once from PipMCP and approve access. PipMCP is an independent service and is not affiliated with Mailmojo.
