What it is and what it does
mailjet-rest is the official Python client for Mailjet's email delivery APIs. It wraps Mailjet's v3, v3.1 (Send API), and v1 (Content API) endpoints, handling authentication, request serialization, and error handling so you can send transactional emails, manage contacts, and interact with templates and segmentation features without building HTTP calls manually.
The package is designed for Python 3.10+ and emphasizes resource safety through context manager support, local-first payload validation, and type hints for IDE autocompletion. It supports both simple email sends and complex payloads via a MessageBuilder, and returns raw response objects for standard HTTP errors rather than raising exceptions, giving you fine-grained control over error handling.
Use it for
- Send transactional emails (password resets, order confirmations) from your application.
- Manage Mailjet contacts, templates, and campaigns programmatically.
- Build and send complex multi-recipient emails with attachments and custom headers.
- Integrate email delivery into a web application using the Send API v3.1.
- Monitor email statistics and webhook events through the Email API ecosystem.
