Connect Claude & ChatGPT to Mailjet

Ask your AI how your last campaign performed, whether a message was delivered or which lists a contact is on, and it reads the answer from Mailjet. It can send transactional emails, manage contacts and lists, and create, test and send campaign drafts, with your approval if you want it.

Try asking

“Was the order confirmation to [email protected] opened?”
The AI finds the message and reads its event history: sent, opened, clicked or bounced.
“How did the September newsletter do?”
It finds the campaign and pulls its statistics for delivered, opened, clicked, bounced and unsubscribed.
“Unsubscribe [email protected] from the Newsletter list.”
It updates his subscription on that list. The contact stays in your account.

What your AI can do

Contacts and lists

Create and update contacts and their custom properties, create lists, and subscribe, unsubscribe or remove contacts on lists.

Campaigns and templates

Create campaign drafts, set their content, send tests and send them to their list, and read templates and sent campaigns.

Sending and statistics

Send transactional emails, follow each message's event history and read sending statistics per account, campaign, list or sender.

“Draft a campaign to the Customers list about our new opening hours.”
It creates a campaign draft with sender and subject and adds the HTML and text content.
“Send a test of that draft to me and Sofie.”
It sends a test of the draft to the two addresses so you can check it before it goes out.
“Which of our sender addresses are validated?”
It lists your sender addresses and domains and shows which ones are validated.

Questions

What can the AI do in Mailjet?

It can read contacts and their properties and list subscriptions, contact lists, campaigns, campaign drafts, templates, sent messages and their event history, sender addresses, your account profile and sending statistics. It can create and update contacts, create lists, manage subscriptions, create and fill campaign drafts, send tests, send campaigns and send transactional emails.

Does the AI see my Mailjet API keys?

No. Your Mailjet API key and Secret key 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 campaign or a transactional email cannot be undone, so send_campaign_draft and send_email 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 HeyMyApps 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?

HeyMyApps has a free plan, and you do not need a credit card to start. Paid plans bill per completed task. You also need your own Mailjet account.

Can I test a campaign before it goes out?

Yes. The AI can send a test of a campaign draft to a few addresses you name. Sending the draft to its whole list is a separate tool, send_campaign_draft, which you can keep switched off or set to require your approval.
