Mailjet is a mid-tier email platform offering both transactional and marketing email with decent pricing. Strengths: real-time collaboration on email templates, reasonable pricing at mid-volume, GDPR compliance (EU-based). Weaknesses: deliverability is inconsistent on shared IPs, analytics are basic compared to competitors, the interface feels dated. Best for EU-based teams needing GDPR compliance and collaborative email editing. For pure deliverability or developer experience, Mailgun or Postmark are better choices.
Mailjet Review 2026: Pricing, Features, and Deliverability
Mailjet: The Collaborative Email Platform
Mailjet sits in an interesting middle ground — more developer-capable than Mailchimp, more marketing-friendly than Mailgun. Their standout feature is real-time collaboration on email templates, letting multiple team members edit simultaneously (like Google Docs for email).
Sinch acquired Mailjet in 2020, making it a sibling to Mailgun under the same parent company. The products remain distinct: Mailgun for developers, Mailjet for marketing teams who also need transactional capability.
Pricing (March 2026)
| Plan | Price | Emails/Month | Key Features |
|---|---|---|---|
| Free | $0 | 6,000 (200/day) | Mailjet branding, basic features |
| Essential | $17/mo | 15,000 | No branding, email preview |
| Premium | $27/mo | 15,000 | Segmentation, A/B testing, automation |
| Custom | Contact sales | 1M+ | Dedicated IP, priority support |
Volume scales: 50K emails on Essential is ~$35/mo, 100K is ~$55/mo. Pricing is competitive at mid-volume but not the cheapest option available.
Strengths
Real-time collaboration. Mailjet's Passport feature lets multiple users edit the same email template simultaneously. For agencies or teams where designers, copywriters, and marketers all touch email, this saves significant back-and-forth.
EU-based, GDPR-compliant. Headquarters in Paris, data centers in EU. For European businesses concerned about data sovereignty, Mailjet is a natural choice.
Transactional + marketing combined. Single platform handles both email types. The API is decent for developers, while marketing teams get visual builders and automation.
Reasonable pricing. The free tier (6K emails/month) is genuinely usable for small projects. Paid plans are competitively priced without the sticker shock of some alternatives.
Weaknesses
Shared IP deliverability variance. On lower-tier plans with shared IPs, inbox placement is inconsistent. I've seen clients on Mailjet struggle with Gmail's Promotions tab more than on Postmark or dedicated-IP SendGrid.
Dated interface. The UI works but feels like it hasn't had a significant refresh in years. Compare to Resend or Brevo's modern interfaces and Mailjet looks tired.
Basic analytics. Email stats are functional but limited. No predictive scoring, minimal engagement insights. For data-driven teams, you'll want more.
Support on lower tiers. Free and Essential tiers get email support only. Response times can be slow. Premium and above get phone support.
Practitioner note: Mailjet's collaboration feature is genuinely useful if you have a team workflow problem. I've recommended it to agencies where email approval chains were killing productivity. For solo operators or dev-heavy teams, that feature is wasted and you're better off with Mailgun or Postmark.
Who Should Use Mailjet
Good fit:
- EU-based teams needing GDPR compliance
- Marketing teams wanting real-time template collaboration
- Mid-volume senders (25K-250K/month) on a budget
- Agencies managing email for multiple stakeholders
Bad fit:
- Developers wanting best-in-class API experience (use Mailgun or Resend)
- High-volume transactional where every millisecond matters (use Postmark)
- Budget-constrained high volume (use AWS SES)
- Teams needing advanced analytics and deliverability tools
Mailjet vs. Alternatives
| Platform | Best For | Collaboration | EU Data Centers |
|---|---|---|---|
| Mailjet | Team collaboration | Yes (real-time) | Yes |
| Mailgun | Developer SMTP | No | Yes |
| SendGrid | All-in-one | No | No (US-based) |
| Brevo | Marketing automation | Limited | Yes |
Practitioner note: Sinch owning both Mailjet and Mailgun creates an interesting dynamic. They're positioned as complementary rather than competitive. If you're a Sinch customer for SMS/voice, consolidating email under their umbrella (either Mailjet or Mailgun) can simplify vendor management.
The Bottom Line
Mailjet is a competent mid-tier email platform. It doesn't excel in any single category — Mailgun has better developer experience, Postmark has better transactional deliverability, Klaviyo has better marketing automation. But it does everything adequately with a unique collaboration feature.
If real-time template collaboration matters to your team, Mailjet is worth considering. If it doesn't, the other features probably won't differentiate it enough from alternatives.
For EU businesses specifically, the GDPR compliance and EU data centers are legitimate advantages that simplify compliance conversations.
If you're evaluating Mailjet against other platforms and want a recommendation based on your specific workflow and requirements, schedule a consultation — I'll help you pick the right tool.

Frequently Asked Questions
Is Mailjet good for transactional email?
Adequate but not exceptional. Mailjet handles transactional email, but deliverability on shared IPs varies. For critical transactional email (password resets, order confirmations), Postmark or SendGrid with dedicated IPs provide more consistent results.
How much does Mailjet cost?
Mailjet offers a free tier (200 emails/day, 6,000/month) with Mailjet branding. Essential plan starts at $17/month for 15,000 emails. Premium starts at $27/month with advanced features. Custom pricing for enterprise volumes.
Who owns Mailjet?
Sinch acquired Mailjet in 2020. Sinch also owns Mailgun, making them sibling products under the same parent company. Mailjet maintains separate branding and product focus (marketing-friendly) while Mailgun targets developers.
Is Mailjet better than Mailgun?
Different focus. Mailjet is better for marketing teams who want collaborative template editing and visual campaign building. Mailgun is better for developers who need API/SMTP relay and don't care about visual editors. Both are owned by Sinch.
Is Mailjet GDPR compliant?
Yes. Mailjet is EU-based (Paris, France) and has been GDPR compliant since the regulation launched. Data processing can be kept within EU infrastructure, which matters for European businesses.
