Buddy's Take on Pricing
Sender wins decisively on pricing. Its free plan offers 2.5x more contacts and emails than Mailjet. Entry-level pricing is less than half Mailjet's cost, and even the Professional tier at $14/month costs less than Mailjet's basic Essential plan. The only justification for Mailjet's premium is if you specifically need its developer features.

Mailjet positions itself as a platform for both marketers and developers, with robust APIs, SMTP relay, and collaborative editing features. The real-time collaboration tools let teams work together on email templates with commenting and approval workflows. Its MJML framework and comprehensive API documentation appeal to technical teams building custom integrations.
Sender takes a simpler approach, focusing on ease of use and value. It includes SMS marketing (which Mailjet lacks entirely), offers 1,600+ email templates, and provides multichannel automation. The interface is more intuitive for beginners, and features like popup builders and behavioral triggers work well for small businesses without technical resources. Both platforms handle basic email marketing well, but Sender's broader feature set at lower prices makes it more appealing for most users.
