AI Email Outreach, AI Content Writing / AI Copywriting, AI Email Deliverability
Mailjet, a product of Sinch, is a powerful email marketing platform that bridges the gap between technical precision and intuitive design. With over 130,000 daily users, it offers a scalable solution for transactional and marketing emails. The conclusion for 2026: Mailjet remains the first choice for teams that value collaborative design and a robust API infrastructure. The core problem: Silos in email creation. In many companies, marketers and developers work in isolation. Marketers need simple drag-and-drop editors, while developers demand full control over the code and API integration. This often leads to rendering errors or workflow delays. The solution: Mailjet's hybrid approach. Mailjet solves this problem with a platform that unites both worlds. With the MJML framework, developers can efficiently code responsive emails, while the intuitive editor allows marketers to customize these templates without any programming knowledge. The result: Increased efficiency and deliverability. By using Mailjet, companies achieve consistent brand management and optimized delivery rates. The integrated validation tools and dedicated IP options ensure that messages reliably land in the inbox, not in spam. Key AI features and unique selling points: AI Email Generator. The new AI assistant supports 21 languages and enables the automatic creation of content based on tone and target audience. This saves valuable time in campaign planning.
Similar to Google Docs, multiple team members can work on an email simultaneously. Comments and permissions can be managed directly in the editor.
The open-source framework MJML ensures that emails are rendered perfectly on all devices, massively reducing technical complexity for developers.
E-commerce companies use Mailjet to create complex automation chains—from welcome series to reactivation campaigns based on user behavior.
Developers integrate the Mailjet API to send system notifications, password resets, and invoices with the highest reliability.
Mailjet offers a tiered model: a free version for beginners, as well as 'Starter' and 'Enterprise' packages for growing needs. Compared to competitors like Mailchimp, Mailjet scores particularly well with its unlimited number of contacts in all plans, with billing primarily based on sending volume. This makes it especially cost-effective for companies with large databases but moderate sending frequency.
