Mailjet has long been a popular choice for businesses that need both transactional and marketing email in one platform. Its generous free plan and collaborative email editor make it especially appealing to small teams. However, as email requirements become more sophisticated, many businesses find themselves needing better deliverability, more advanced automation, greater scalability, or a more developer-friendly experience.
The email landscape has also evolved rapidly. Developer-first platforms like Resend have raised the bar for API simplicity, while marketing-focused providers such as Brevo now offer more powerful automation and customer engagement features. At the same time, pricing and free-tier changes across major providers have prompted many businesses to reassess their options.
This guide compares the 10 best Mailjet alternatives for 2026, evaluating each platform based on deliverability, pricing, ease of use, features, and overall value to help you choose the right solution for your business.
What Is Mailjet?
Mailjet is a cloud-based email platform that combines email marketing and transactional email in a single service. Founded in France in 2010 and later acquired by Sinch, it helps businesses send newsletters, promotional campaigns, password resets, receipts, account notifications, and other automated emails.
Unlike providers that specialize in either marketing or transactional email, Mailjet supports both through one platform. Users can design emails with a drag-and-drop editor, send transactional messages via SMTP or REST API, manage contacts, personalize campaigns, and collaborate on templates with role-based permissions.
Key features include:
- Email marketing campaigns
- Transactional email API
- SMTP relay
- Drag-and-drop email builder
- Dynamic templates
- Contact management
- Basic marketing automation
- Real-time analytics
- A/B testing
- Team collaboration
- Email personalization
- Deliverability monitoring
Mailjet is a solid choice for small and medium-sized businesses looking for an affordable all-in-one email solution. Its free plan and support for both marketing and transactional emails make it easy to get started without managing multiple platforms.
However, businesses with more advanced requirements may outgrow it. Marketing teams often need stronger automation and customer journey features, while developers may prefer platforms with more modern APIs and faster implementation. High-volume senders can also find more cost-effective options designed for large-scale email delivery.
Why Look for a Mailjet Alternative?
Mailjet is a dependable email platform for many businesses, but it isn’t the right fit for every use case. As organizations grow, their email needs often become more complex, requiring capabilities beyond what Mailjet offers. Here are some of the most common reasons businesses decide to switch.
1. Limited Marketing Automation
Mailjet provides basic automation for common scenarios, such as welcome emails and simple autoresponders. However, businesses running sophisticated marketing campaigns often need advanced customer journeys, behavioral triggers, conditional workflows, lead scoring, and more granular audience segmentation.
2. Pricing Can Increase with Volume
Mailjet is affordable for small and medium-sized senders, but costs can rise as email volume grows. Businesses sending large numbers of transactional or marketing emails often reassess their email provider to improve cost efficiency — a savings calculator can help quantify whether a switch is worth it.
3. Basic Developer Tools
Mailjet offers REST APIs and SMTP integration, but some development teams require a more streamlined developer experience. Faster implementation, clearer documentation, modern SDKs, comprehensive logs, testing environments, and debugging tools can be important for teams building and maintaining email-powered applications.
4. Limited CRM Functionality
While Mailjet includes contact management, it is not a full customer relationship management platform. Businesses that need features such as sales pipeline management, customer lifecycle tracking, advanced lead management, and detailed customer profiles may require a more comprehensive solution.
5. Growing Transactional Email Demands
As businesses scale, transactional emails become increasingly critical. Applications that rely on password resets, account verification, receipts, and security notifications often require consistently fast delivery, high reliability, detailed delivery logs, and robust monitoring. A healthy sender reputation matters just as much, because it decides whether those emails reach the inbox at all.
6. Scalability Requirements
As email programs grow, businesses may need higher sending limits, more flexible infrastructure, stronger account controls, and enterprise-grade features to support larger teams and increasing email volumes.

1. ConvertNow (Best Overall Mailjet Alternative)
ConvertNow is an email marketing and transactional email API platform built on email infrastructure it owns and operates directly. It is the only platform on this list that includes both a full email marketing suite and a transactional email API on the same account, the same billing, and the same contact database.
The core differentiator is how ConvertNow is priced. Unlike Mailjet and most other platforms that charge by contacts stored, ConvertNow charges by emails sent. Unlimited contacts are included on every plan including the free plan. A school with 50,000 families on their list pays the same as one with 5,000. A SaaS company with 100,000 inactive trial users does not pay to store contacts it barely emails. See the full pricing page for the complete volume ladder.

Instead of combining marketing campaigns and transactional messaging, it focuses exclusively on time-sensitive communication such as password resets, authentication codes, purchase confirmations, and application notifications.

Which Mailjet alternative is cheapest?
ConvertNow’s free plan sends 10,000 emails per month with unlimited contacts and no credit card required, making it the most generous free tier on this list.

Is Mailjet good for transactional emails?
Yes. Mailjet supports transactional emails through SMTP and APIs, making it suitable for notifications, password resets, and automated messages. However, businesses with more advanced transactional email needs may prefer platforms focused specifically on delivery performance and developer tools.
Which Mailjet alternative has the best deliverability?
Deliverability depends on sender reputation, authentication, email practices, and sending volume. Postmark is widely regarded as the strongest for transactional deliverability due to its separated infrastructure. ConvertNow manages its own sending infrastructure directly, giving it full control over reputation management without relying on shared third-party pools.
Which Mailjet alternative is best for developers?
Developers typically choose platforms that offer reliable APIs, strong documentation, flexible integrations, and detailed email logs. Resend, Postmark, Mailgun, SendGrid, and ConvertNow are all strong options for application-based email sending.

Migrating from Mailjet usually involves exporting contacts, recreating templates, updating SMTP settings or API credentials, authenticating your domain, and monitoring email performance after the transition. ConvertNow handles migration for free, same day, including list import and domain setup.
Conclusion
Mailjet remains a solid choice for businesses that need both marketing and transactional email capabilities in one platform. However, as email requirements become more specialized, many organisations look for solutions that better match their priorities, whether that is advanced automation, lower costs, faster delivery, or stronger developer tools.
For organisations tired of paying per contact, ConvertNow is the strongest overall alternative. It includes both email marketing and a transactional API on the same plan, charges only for emails sent, and gives every plan unlimited contacts from the free tier upward.
For an all-in-one multi-channel replacement, Brevo provides email, SMS, CRM, and automation in one platform. Businesses focused purely on transactional email can benefit from Postmark, Resend, Mailgun, or SendGrid. High-volume senders often prioritize the scalability and pricing flexibility of Amazon SES.
The right Mailjet alternative depends on your email volume, technical requirements, marketing goals, and growth plans. Evaluating these factors before switching will help you choose a platform that supports your business both now and in the future.
