Mailjet review
Bottom line
Mailjet is a combined email marketing and sending platform, with a visual editor for campaigns and an API and SMTP relay for transactional mail under one account. Its clearest strength is the free plan at 6,000 emails per month and the low entry price of $9 per month. The main limits to watch are the 200-per-day cap on the free plan, and that team management, automations and a dedicated IP require the $29 Premium plan. Teams that send both campaigns and app email from one place should choose it.
What is Mailjet?
Mailjet is an email platform that combines marketing campaigns, automated workflows and transactional sending through an API and SMTP relay. It addresses the common split where marketing teams and developers run email through separate tools. A welcome series and a password reset can be sent from the same account, with shared templates, contacts and reporting.
Marketers build emails in a drag-and-drop editor, reuse templates, and create audience segments by describing the group they want in plain language. Automation workflows can be triggered by user actions, and A/B tests run on subject lines and content. Developers connect through a RESTful Email API or SMTP relay, test in sandbox mode, and receive webhook events for opens, clicks, bounces and blocks. Subscription forms and landing pages feed directly into contact lists, with double opt-in available.
Mailjet serves freelancers, small businesses, mid-sized companies and enterprises. The free plan includes 6,000 emails per month with a 200-per-day cap and 1,000 contacts, and no credit card is required at signup. Paid plans start at $9 per month for Starter, then rise to $19 for Essential and $29 for Premium, which adds automations, advanced statistics, team management and a dedicated IP. Higher-volume senders can request custom enterprise plans.
Compared with typical email tools, Mailjet keeps the marketing editor and the developer API in one product rather than separate purchases. It highlights EU-based data centers, ISO 27001 and SOC 2 certification, and GDPR tools such as email tracking consent and anonymous tracking. It is also a Certified Senders Alliance participant. Its AI features, including an assistant that drafts campaigns and an MCP server for connecting Claude Desktop, extend the same account.
