What it does
Mailjet's Email API sends transactional and marketing e-mails from your application, such as order confirmations and newsletters, and manages contacts, templates, statistics and webhooks. Send a JSON request to the Send API with your API key and secret, or use SMTP relay. Free with a free API key: 6,000 e-mails a month with at most 200 a day and 1,000 contacts; paid plans remove the daily limit and the Mailjet logo. An official open-source MCP server (github.com/mailgun/mailjet-mcp-server) lets AI agents use Mailjet's contacts, campaigns and statistics APIs.
