Mailjet MCP server

What the model can do

Mailjet email: campaigns sent and drafted with delivery, open and click counts, individual messages and their status in a time window, statistics by day or campaign, contacts and contact lists. Can add or update contacts, add them to, remove them from or unsubscribe them from lists, create lists, create and edit campaign drafts and their content, test-send, send, schedule or unschedule a draft, and send a single email, when you ask.

Acts, when you ask

These change something in Mailjet. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

• mailjet_create_contactAdds a person to the Mailjet account's global contact list, with an email and optionally a name.
• mailjet_create_campaign_draftCreates a Mailjet campaign draft with a subject, an internal title, a locale and optionally a sender and contact list.
• mailjet_send_emailSends one email through Mailjet's Send API from a validated sender address, to up to 20 recipients across to, cc and bcc.
• mailjet_send_campaign_draftSends a Mailjet campaign draft now to every subscribed contact of its list or segment.
• mailjet_schedule_campaign_draftSchedules a Mailjet campaign draft to go to its whole list at a time (UTC).
• mailjet_cancel_campaign_scheduleCancels a Mailjet campaign draft's scheduled send; the draft stays and nothing is sent.
• mailjet_send_campaign_testSends a test of a Mailjet campaign draft to up to 5 addresses the user names; the draft's status is unchanged.
• mailjet_set_campaign_draft_contentWrites the body of a Mailjet campaign draft.
• mailjet_update_campaign_draftChanges a Mailjet campaign draft's settings: title, subject, sender, reply-to, list or locale.
• mailjet_manage_contact_listsFor one existing Mailjet contact (by id), adds them to, removes them from, or unsubscribes them from up to 10 lists.
• mailjet_manage_list_contactAdds an email address to one Mailjet list (creating the contact if it is new), removes it from the list, or unsubscribes it from the list.
• mailjet_create_contact_listCreates an empty Mailjet contact list with a unique name.
• mailjet_update_contactChanges a Mailjet contact's name, or puts them on or takes them off the campaign exclusion list (an excluded contact gets no marketing email).

Connect it

First connect Mailjet on Dashboard → Connections, then add Memtro to your client once. The Mailjet tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared Mailjet connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

• › Is priya@brightwave.example unsubscribed?
• › Send a test of the March product update draft to me and Laura

Questions

Is this an official Mailjet MCP server?

No. It is Memtro's MCP server with Memtro's Mailjet connector behind it: the connector reads Mailjet through its API with the credentials you connect on Dashboard → Connections, and Mailjet publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in Mailjet?

Only when you ask, and only what it has been granted: add a contact to the account's contact list (not to any mailing list); create a campaign draft; send a single email; send a campaign draft now; schedule a campaign draft; cancel a campaign draft's schedule; send a test of a campaign draft; write a campaign draft's content (replaces what was there); edit a campaign draft's settings; add a contact to, remove from or unsubscribe from several lists; add an email to, remove from or unsubscribe from one list; create a contact list; update a contact's name or campaign exclusion. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
