Mailjet is an email marketing platform, part of Sinch, that builds AI into campaign creation and audience targeting. Its AI Email Generator drafts full campaigns (subject lines, copy and layout) from a prompt, the Mailjet AI Assistant rewrites text and adjusts tone inside the editor, and AI Segmentation turns a plain-language audience description into reviewable filter logic.
AI Segmentation addresses a specific friction point. A traditional filter interface requires you to know which fields and conditions match the audience you have in mind, while here you describe the audience in words and review the generated logic before anything is sent. Human oversight stays in place; only the translation work is removed.
A dedicated MCP server also connects Claude Desktop to your campaign performance data, so you can ask questions about results conversationally. It needs a compatible client and some technical setup.
Beyond the AI layer, Mailjet offers a drag-and-drop email editor with real-time collaboration, marketing automation workflows, A/B testing, and an email API and SMTP relay for developers. It also lists a wide range of integrations. For current tiers and any free plan, check Mailjet’s pricing page.
Who Mailjet suits
Mailjet fits teams that want AI help with drafting and segmentation but still want to review output before sending. It also suits groups where marketers and developers share one platform, since the editor and the API sit together. A small team that only needs simple newsletters may find the full feature set more than it needs.
