EmailOctopus vs Mailjet Comparison: Everything You Need to Know Before Choosing

Mailjet is a cloud-based email platform that combines marketing campaign tools with a transactional email delivery service, aimed at teams that want to design, send and track email without deep technical expertise. Founded in France and now part of Sinch, the product positions itself around collaboration: several team members can work on the same template simultaneously, leave comments and manage approvals, which suits marketing departments and agencies where design, copy and sign-off involve different people. Its core approach is to offer a single account through which organisations can run newsletters and promotional campaigns via a drag-and-drop editor while developers send receipts, password resets and notifications through a SMTP relay or REST API, with both streams benefiting from the same deliverability infrastructure. The company also emphasises data protection, with GDPR compliance and European data hosting as notable differentiators. The platform also supports multiple sub-accounts and user permission levels, which helps agencies and larger organisations separate brands, clients or business units while keeping billing and administration consolidated under a single account. Key features include a responsive drag-and-drop builder and MJML-based templating language, contact list management and segmentation, A/B testing, marketing automation workflows, and real-time statistics covering opens, clicks, bounces and unsubscribes. Transactional capabilities include templating with personalisation variables, webhooks for event tracking and detailed sending logs, while deliverability tools and dedicated IP options are available on higher tiers. Integrations cover common CMS, e-commerce and CRM platforms such as WordPress, Shopify, Salesforce and Zapier, alongside libraries for popular programming languages. Mailjet is used by small businesses, e-commerce retailers, SaaS companies and agencies, particularly in Europe, that want both marketing and transactional email from one provider at moderate cost. Being entirely web-based, it requires no local installation. A free version is available with a capped monthly sending allowance, a free trial is offered, and paid plans start from around USD 17 per month.
