Mailjet email marketing has quietly become one of the sharpest choices for small teams that need to send volume without breaking the budget. Founded in 2011 and now part of Sinch, Mailjet serves over 100,000 customers across 150 countries, combining affordability with features that most platforms reserve for enterprise tiers. The platform scored 89/100 in deliverability testing since October 2025, a result that matters far more than flashy interface screenshots when your emails actually need to land in inboxes.
Key Takeaways
- Mailjet email marketing starts at $9/month with volume-based pricing that scales predictably as you grow.
- Real-time collaboration features let marketing and dev teams edit campaigns simultaneously, a rarity among email platforms.
- 89/100 deliverability score reflects strong infrastructure, built-in email validation, and domain authentication tools.
- Free plan includes 6,000 emails and 1,000–1,500 contacts, enough for early-stage testing.
- Automation capabilities lag specialist platforms like Mailchimp, limiting complex segmentation on lower tiers.
Mailjet Email Marketing Pricing and Plans
Volume-based pricing is Mailjet’s defining economic choice. Instead of charging per contact—which punishes you for growing your list—the platform charges by email volume sent. The free plan grants 6,000 emails and 1,000–1,500 contacts monthly, enough for newsletters and small transactional sends. Paid plans start at $9/month and climb based on volume, with unlimited contacts on all plans except Starter. At the $17/month tier, you unlock 15,000 emails monthly with unlimited contacts, 500 email validations, segmentation, AI tools, one sub-account, and online support.
This structure rewards scaling differently than contact-based competitors. If you have 50,000 contacts but send only 10,000 emails monthly, you pay far less than a platform charging per contact. Prepaid flexibility means you control spend—no surprise invoices. For teams sending high volumes of transactional emails (password resets, invoices, notifications), this model makes economic sense.
Real-Time Collaboration: Where Mailjet Stands Apart
Few email platforms let multiple team members edit a campaign simultaneously. Mailjet does, with AI-powered real-time collaboration that mirrors Google Docs—comments, approvals, role-based access, and team sub-accounts built in. A user on G2 noted the appeal: “I like Mailjet’s built-in GDPR compliance because it gives me peace of mind. I also appreciate the AI-powered real-time collaboration, which feels a bit like using Google Docs for email”.
This feature closes a friction point in most email workflows. Marketers draft, developers review for technical accuracy, compliance checks approvals—all in one interface without exporting files or juggling versions. Role-based access ensures junior team members cannot accidentally send to the full list. For distributed teams, this eliminates the email-and-Slack back-and-forth that wastes hours monthly.
Deliverability and Email Validation
Mailjet’s 89/100 deliverability score reflects serious infrastructure investment. The platform includes built-in email validation (500 validations monthly on some plans), visual email checks, domain authentication, and bot filtering to protect sender reputation. Large-scale infrastructure and ISP relationships mean your emails have a fighting chance against spam filters.
However, some users report mixed results. One reviewer noted: “Our emails frequently landed in the spam folder, especially with Mailjet’s French-based IPs”. Another mentioned occasional over-filtering of legitimate opens by bot filtering. Deliverability depends partly on sender behavior—a clean list and proper authentication help, but no platform guarantees inbox placement. The validation tools reduce bounces and hard blocks, a meaningful advantage for teams managing large contact lists.
Developer Features and API Strength
Mailjet email marketing shines for technical teams. The API and SMTP are built for transactional email at scale—password resets, order confirmations, alerts—without the overhead of marketing automation platforms. Integrations with CRMs mean status messages and promotional emails flow through your existing tools. High-volume bulk sending, SMS capabilities, and segment-to-automation connections give developers the hooks they need.
One user summed it up: “We integrated Mailjet with our CRM, and all status messages and promotional emails go through it smoothly”. For startups and mid-market companies running custom workflows, this flexibility beats rigid marketing platforms that force you into their automation logic.
Analytics, Segmentation, and AI Tools
In-depth metrics break down performance by location, device, and email client, with bounce reports that include ISP codes for diagnosing deliverability problems. Link-level and UTM tracking appear on higher plans, letting you trace clicks back to specific campaigns. Message logs provide audit trails for compliance. AI-powered segmentation and subject-line/copy generators help smaller teams punch above their weight.
Automation remains a weak point. Mailjet’s automation is improving but stays basic compared to specialist platforms like ActiveCampaign or Mailchimp. Complex audience filters and highly targeted multi-step campaigns require workarounds. For teams running simple drip sequences and welcome series, this is fine. For sophisticated nurture campaigns with conditional logic, you may outgrow Mailjet.
Ease of Use and Interface Design
The drag-and-drop email editor is intuitive for beginners and pros alike. Users consistently praise affordability, ease of use, and professional-looking email output. No steep learning curve means your team launches campaigns faster than platforms buried in settings menus. The interface feels modern without sacrificing clarity.
Customer support is a known weak point. Some users note slower response times compared to competitors. For critical issues, this can frustrate teams on tight deadlines. Email support and online documentation exist, but live chat is not always available.
Mailjet vs. Mailchimp and ActiveCampaign
Mailchimp dominates the SMB space through brand recognition and a free tier that feels generous. But Mailchimp’s free plan caps you at 500 contacts, forcing an upgrade sooner. Mailjet’s free tier extends to 1,000–1,500 contacts and 6,000 emails, better for testing. Mailchimp excels at advanced automation and template variety; Mailjet wins on real-time collaboration and deliverability focus. ActiveCampaign offers deeper CRM integration and behavioral automation but costs significantly more. For teams prioritizing affordability and developer-friendly APIs, Mailjet edges both.
Who Should Use Mailjet Email Marketing?
Mailjet email marketing fits SMBs, growth-stage startups, and teams with mixed marketing and dev responsibilities. If you send high email volumes but have modest contact lists, the volume-based pricing model saves money. If your team spans marketing and engineering, real-time collaboration eliminates handoff friction. If deliverability and API flexibility matter more than advanced automation, Mailjet is a smart pick. Avoid it if you need sophisticated multi-step automation or extensive template libraries.
Is Mailjet’s free plan enough to start?
Yes, for initial testing. The free plan includes 6,000 emails and 1,000–1,500 contacts monthly, enough for small newsletters and transactional sends. You get the full editor, basic analytics, and segmentation. Upgrade when you exceed these limits or need advanced features like AI tools and higher validation allowances.
How does Mailjet email marketing compare on customer support?
Mailjet offers email support and online documentation but lags competitors like Mailchimp on response speed. Live chat availability varies by plan tier. For urgent issues, this can be frustrating, though most technical questions are answerable through the knowledge base.
Can you use Mailjet for transactional and marketing emails?
Absolutely. Mailjet’s API and SMTP handle transactional email (password resets, invoices, alerts) at scale, while the visual editor supports marketing campaigns. You can even connect segments to automations and transactional sends, blending the two workflows. This dual capability appeals to teams running lean operations without separate platforms.
Mailjet email marketing punches above its price point. For SMBs tired of contact-based pricing and teams that need their dev and marketing staff in the same editing window, it solves real problems. The 89/100 deliverability score proves the infrastructure is solid, and the API gives developers room to build. Automation lags specialist platforms, and support could be faster, but neither is a dealbreaker for the right team. Start free, scale on volume, and let real-time collaboration speed up your campaigns.
