19 Mailjet Alternatives Worth Considering

Formerly Sendinblue. Complete marketing platform with email, SMS, chat, and CRM. Often compared directly to Mailjet as a European alternative.

Brevo includes marketing automation on its $9/month Starter plan - the same feature that requires Mailjet's $27/month Premium tier - making it a significantly cheaper option for teams that need workflows. The unlimited contacts model means you pay based on email volume, not list size, which works better for businesses with large but infrequent-send audiences. Being EU-based like Mailjet, GDPR compliance isn't a concern. The interface can feel cluttered with the breadth of features, and branding removal costs extra. Best for budget-conscious European teams who want email, SMS, and CRM without paying premium prices.

Industry standard transactional email owned by Twilio. Reliable infrastructure used by Uber and Airbnb.

More developer-focused than Mailjet. SendGrid handles billions of emails monthly with a scale track record that Mailjet can't match, and the Essentials plan at $19.95/month for 50,000 emails is competitively priced. Marketing Campaigns is available as a separate product, giving you both transactional and marketing under one roof. The developer experience shows its age compared to modern alternatives, and deliverability on shared IPs can be inconsistent. Best for teams that need proven enterprise-scale infrastructure and don't mind a less polished interface in exchange for battle-tested reliability.

Fast, reliable transactional email focused on deliverability. Known for lightning-fast delivery and excellent support.

Postmark achieves industry-best deliverability by strictly vetting every customer and rejecting anyone who might harm shared IP reputation - a level of quality control Mailjet doesn't apply. At $15/month for 10,000 emails, pricing is comparable to Mailjet's Essential tier, and Message Streams let you separate different email types for better monitoring. The tradeoff is clear: no marketing campaigns, no automation, no team collaboration features. Best for teams sending mission-critical transactional emails like password resets, receipts, and 2FA codes where inbox placement is non-negotiable.

Developer-focused transactional email API. Sister company to Mailjet under Sinch.

More API-focused, less marketing features. Mailgun includes email validation as a built-in feature and supports inbound email parsing, both of which Mailjet lacks at lower tiers. The Foundation plan starts at $35/month for 50,000 emails after a late 2025 price increase that doubled Flex plan rates. Since Sinch owns both Mailgun and Mailjet, switching between them doesn't reduce your dependency on a single corporate parent. Best for developers who need a pure transactional API with email validation and inbound processing, and don't mind staying within the Sinch ecosystem.

Amazon's email service. The cheapest option at $0.10 per 1,000 emails. Pure infrastructure with no marketing features.

At 100,000 emails/month, SES costs $10 versus Mailjet's $90+ on Premium - the savings are dramatic at scale. You get AWS-grade reliability and EU region support for data residency, but absolutely nothing else: no template editor, no collaboration tools, no deliverability dashboard, no bounce management out of the box. Only makes sense for engineering teams already invested in the AWS ecosystem who can build their own email layer on top. If you're comparing SES to Mailjet, you're essentially choosing between convenience and cost.

Modern transactional email with beautiful developer experience. Built by former Stripe engineers.

React email templates. Resend's API is genuinely a joy to use - type-safe SDKs for every major language, React Email for building templates as components, and documentation that reads like a well-crafted tutorial. The free tier covers 3,000 emails/month, with paid plans at $20/month for 50,000 emails. Unlike Mailjet, there's no team collaboration or marketing campaigns, but the developer experience is a clear generation ahead. Best for modern development teams who want the cleanest possible transactional email integration and don't need Mailjet's collaborative template editing.

Behavioral email automation for SaaS and apps. Powerful event-driven messaging with excellent segmentation.

Customer.io lets you build automation workflows triggered by any user behavior - page views, feature usage, billing events - across email, push, SMS, and in-app messages simultaneously. The event-based architecture is far more sophisticated than Mailjet's basic automation, which only unlocks at the $27/month Premium tier. At $100/month for 5,000 profiles, it's dramatically more expensive but operates in a different league of capability. Best for product-led growth companies with complex user journeys who need multi-channel behavioral messaging that Mailjet's marketing tools can't deliver.

Creator-focused email marketing for newsletters, courses, and content. Not for transactional, but excellent for marketing.

ConvertKit (now Kit) includes landing pages, digital product sales, and newsletter monetization tools that Mailjet doesn't offer - making it a complete creator business platform rather than just an email tool. The free plan covers 1,000 subscribers with basic features, and the Creator plan at $29/month adds automation and integrations. The visual automation builder is more intuitive than Mailjet's workflow editor. No transactional email capability and limited design flexibility keep it firmly in the creator/newsletter space. Best for content creators, course sellers, and newsletter writers who want an opinionated platform built for their specific needs.

SMTP relay service with good deliverability. Simpler alternative to SendGrid/Mailgun for SMTP needs.

SMTP2GO focuses on reliable email delivery through SMTP relay and REST API - a simpler, more focused approach than Mailjet's combined transactional and marketing platform. At $15/month for 40,000 emails on paid plans, the per-email cost is competitive, and the free tier includes 1,000 emails/month for testing. Dedicated IPs are available on higher plans for teams wanting full control over their sending reputation. No marketing features, no collaboration tools, no visual editor. Best for teams that just need emails to arrive reliably without the complexity of a full marketing platform.

E-commerce email marketing powerhouse. Deep Shopify integration with product recommendations and abandoned cart.

Klaviyo's deep e-commerce integrations pull in purchase history, browsing behavior, and cart data to power highly personalized automations that Mailjet's general-purpose platform can't replicate. The free tier covers 250 contacts, with paid plans scaling based on list size - expect around $20/month for 500 contacts and escalating quickly from there. Revenue attribution lets you see exactly which emails drive sales, a metric Mailjet doesn't track. The pricing gets expensive fast at scale, and it's overkill for non-e-commerce businesses. Best for Shopify and e-commerce stores that need advanced product recommendations and abandoned cart recovery.

Modern email marketing built for SaaS startups. Simple, beautiful interface with focus on product updates and user lifecycle.

Loops combines transactional and marketing email in one platform with a clean UI that makes Mailjet's interface feel dated by comparison. Every plan includes all features - no tiered gating like Mailjet's Essential vs Premium split - which simplifies the buying decision. At $49/month for 5,000 subscribers it's pricier than Mailjet, but you get a purpose-built SaaS email platform rather than a generic tool adapted for software. The platform is newer with a shorter track record, and there's no team collaboration feature. Best for early-stage SaaS teams who want a modern, opinionated email platform without Mailjet's general-purpose complexity.

Clean, affordable email marketing with a generous free tier and included landing pages. MailerLite offers a modern drag-and-drop editor, website builder, and landing page creator that Mailjet doesn't include at any tier.

At $18/month for 2,500 subscribers (scaling to around $50 for 10k), pricing is competitive with Mailjet's Essential plan, and automation is included without the Premium upgrade Mailjet requires. The interface is noticeably cleaner and more intuitive. The tradeoff: no transactional email API like Mailjet offers, no real-time collaboration, and the approval process can delay account setup by days. Best for small businesses and creators who want a modern email marketing platform without Mailjet's transactional overhead.

Powerful marketing automation with built-in CRM and sales pipeline. ActiveCampaign's visual automation builder is widely regarded as the best in the industry - far more capable than Mailjet's workflows, which require the $27/month Premium tier to even access.

The built-in CRM with deal tracking and lead scoring eliminates the need for a separate sales tool. At $79/month for 10,000 contacts, it's more expensive than Mailjet but the automation depth justifies the cost for complex workflows. The learning curve is significant, and the interface can feel overwhelming for teams coming from Mailjet's simpler setup. No transactional API and no real-time template collaboration. Best for teams with complex multi-step automation needs who've outgrown Mailjet's basic workflow capabilities.

The most recognized email marketing platform with 300+ integrations and a massive ecosystem. Mailchimp offers a broader feature set than Mailjet - landing pages, social ads, website builder, Creative Assistant for design - but at a significantly higher price.

At $110-135/month for 10,000 contacts versus Mailjet's $27/month Premium, you're paying 4-5x more. Mailchimp controversially counts unsubscribed contacts toward your bill. The Intuit acquisition has added features but also complexity. Mandrill (transactional add-on) requires a Standard plan, adding more cost. Best for teams who need maximum integrations and don't mind paying a premium for the most widely-supported email platform in the market.

Transactional email from the MailerLite team with built-in email verification and SMS. MailerSend's drag-and-drop template builder and email verification are features Mailjet's lower tiers don't include, and the API is clean and well-documented.

At $28/month for 50,000 emails, it's competitive with Mailjet's Essential tier for pure transactional volume. The free tier covers 3,000 emails/month for testing. Unlike Mailjet, there's no real-time template collaboration or full marketing campaign suite - it's transactional-focused with basic broadcast capability. Best for teams that need reliable transactional delivery with email verification and don't need Mailjet's marketing and collaboration features.

Budget transactional and marketing email with simple per-email pricing. Elastic Email offers both API and SMTP relay plus a campaign builder - similar to Mailjet's hybrid approach but at lower prices.

At $25/month for 25,000 emails with straightforward per-email pricing beyond that, budgeting is simpler than Mailjet's tiered plans. Email validation is included, matching a feature Mailjet charges premium for. The developer experience and interface aren't as polished as Mailjet's, and deliverability can be inconsistent on shared IPs. Best for bootstrapped teams sending moderate volumes who want Mailjet's hybrid transactional-plus-marketing approach at a lower price point.

Full marketing and sales platform with CRM, email, landing pages, and analytics. HubSpot is in a completely different league than Mailjet - it's a comprehensive business platform, not just an email tool.

The free CRM includes basic email marketing for up to 2,000 sends/month, and the Marketing Hub Starter at $20/month adds more features. But real marketing automation requires Professional at $890/month, which is dramatically more expensive than Mailjet. The email editor, analytics, and automation are all tightly integrated with the CRM, giving you a unified view of every contact's journey. Best for growing companies that need CRM, email, landing pages, and sales tools in one platform and have the budget for it.

Enterprise transactional email with predictive deliverability analytics, now part of Bird. SparkPost's Signals product provides predictive insights that alert you to reputation issues before they impact inbox placement - something Mailjet's analytics don't offer.

The platform handles massive volumes with proven infrastructure powering a significant share of commercial email worldwide. Pricing is custom and enterprise-focused, which means talking to sales rather than self-serving like Mailjet. The Bird acquisition introduces some uncertainty about the product roadmap. Best for enterprise senders doing millions of emails who need deep deliverability intelligence beyond what Mailjet's reporting provides.
