About mailjet

Mailjet is an email marketing and transactional email platform combining a drag-and-drop email editor for marketers with a RESTful Email API, SMTP relay, and webhooks for developers. It supports both marketing campaigns and transactional messages (e.g., password resets, notifications) from a single system, with shared templates and a unified dashboard for tracking sends. SDKs are available for PHP, Python, Node, and other languages, and the platform includes a sandbox mode for testing before sending live.

The platform provides audience segmentation, automation workflows triggered by user actions, A/B testing on subject lines and content, a form builder, landing page builder, and a preference center. AI-assisted tools include an email generator, an in-editor writing assistant, natural-language audience segmentation, and an MCP server for querying campaign performance through Claude Desktop. Deliverability features include reputation monitoring, email address validation, inbox preview testing, dedicated IP addresses, and domain authentication.

Mailjet is built for teams where marketers and developers collaborate, offering shared workspaces, user roles, approval flows, real-time co-editing, and subaccounts for managing multiple brands or client accounts. Infrastructure is ISO 27001 and SOC 2 certified, with EU-based data centers, a 99.99% SLA, GDPR compliance, and Certified Sender Alliance participation. It integrates with over 100 third-party tools including WordPress, WooCommerce, HubSpot, Shopify, and Google Cloud.
