Where It Lands
The template appears in Mailjet under Content → Email Templates, ready to use. From there, Preview lets you check the email in mobile and desktop views.Editing and Re-exporting
From the template list, Edit opens the HTML code editor. Brew templates are not editable in Mailjet’s drag-and-drop editor. Make design changes in Brew and re-export. To send a test email, open the Edit view and use the Preview & Test option.From an Agent or Code
From an agent,export_email over MCP exports a design to Mailjet. From code, send POST /v1/emails/{emailId}/export with "provider": "mailjet". Connect Mailjet in the app first.
Export is free. Pass dryRun: true to check the design and the connection without creating a template. A dry run doesn’t test whether Mailjet accepts the template: only a real export does.
If your Mailjet account has more than one active sender, pass senderEmail to choose one. With exactly one, Brew picks it for you.
The template takes the email’s title unless you pass templateName (up to 100 characters), and the response returns its templateId. If an export fails, the error says why:
INTEGRATION_NOT_CONNECTED: Mailjet isn’t connected to this brand. Connect it on the Integrations page.EXPORT_UNSUPPORTED: Mailjet rejected a field value it doesn’t support. Change the value and export again.EXPORT_PROVIDER_ERROR: Mailjet refused or failed the export. Check the connection and retry.
Requirements
- A Mailjet account
- Your API Key and Secret Key (Account Settings → API Key Management)
