What Mailjet is

Mailjet is an email platform for marketing teams and developers who need to create, send, and automate marketing or transactional messages. Its drag-and-drop editor helps teams design responsive emails, while marketing tools cover forms, landing pages, audience segmentation, preference centers, personalization, tracking, A/B testing, previews, and address validation. Automation workflows can send messages in response to customer actions, and real-time analytics provide campaign information.

For developers, Mailjet offers a RESTful Email API, SMTP Relay, Parse API, Event API, SDKs, webhooks, and an MCP Server. Teams can work in shared spaces, set user roles and approval flows, and collaborate on campaigns. Mailjet lists more than 100 ready-to-use integrations, including WordPress, WooCommerce, HubSpot, Shopify, and Google Cloud, and supports custom integrations through its API. Its deliverability tools include monitoring, reputation protection, email previews, dedicated IPs, and domain authentication. Mailjet says its infrastructure uses ISO 27001 and SOC 2 certified systems, with customer data kept in EU data centers. The free plan includes 6,000 emails monthly, a 200-per-day cap, and 1,000 contacts. Paid monthly plans start at $9 a month.
