Mailjet Review 2026: Pricing, Email Marketing, Automation and API

Mailjet is an email marketing and transactional email platform built for businesses that need both marketer-friendly campaign tools and developer-focused email infrastructure.

Unlike platforms focused almost entirely on newsletters, Mailjet combines marketing campaigns with transactional sending through SMTP relay and REST APIs. This makes it relevant to companies that want to manage newsletters, promotional campaigns, password resets, order confirmations, product notifications, and other email communication from the same ecosystem.

Mailjet was founded in Paris in 2010 and is now part of Sinch.

The platform currently serves marketers, developers, agencies, ecommerce businesses, and larger email programs through Free, Starter, Essential, Premium, and Custom plans.

Two recent changes are particularly important for a 2026 review.

Mailjet updated pricing on September 9, 2026, and it has also introduced a newer visual Automation builder with more flexible triggers, conditions, events, timers, and webhook-driven workflows.

Mailjet Pricing in 2026

Annual billing currently receives a 10% discount. Mailjet increased Essential and Premium pricing effective September 9, 2026. Starter remained $9/month

Mailjet prices primarily according to monthly sending volume and plan functionality.

Free

$0/month

Includes:

• 6,000 emails per month
• maximum 200 emails per day
• up to 1,000 contacts
• Email Editor
• email templates
• SMTP relay
• Send API
• webhooks
• basic statistics
• subscription forms

The Free plan does not require a credit card.

The main limitation is the 200-email daily sending cap. A contact list above 1,000 contacts also causes a send hold until the account is brought back within the limit or upgraded.

For a small newsletter or developer testing Mailjet’s API, this is still a useful permanent free tier.

Starter

$9/month

Starter includes 8,000 emails per month with no daily sending limit and supports up to 2,000 contacts.

It adds:

• Brand Kit
• online support
• anonymous tracking
• one subaccount

Starter is mainly positioned between the Free and Essential tiers.

One limitation worth noticing is branding. Mailjet’s logo cannot currently be removed from Free or Starter email-editor templates.

Essential

$19/month for 15,000 emails

Essential removes the contact limit and adds more serious marketing functionality.

Current features include:

• unlimited contacts
• segmentation
• AI-assisted content creation
• 500 email address validations
• 500 Email Previews per month
• custom unsubscribe page
• removal of Mailjet branding
• ticket support
• one subaccount

Essential is likely to be the more practical starting point for a growing email marketing program that needs segmentation but does not yet require advanced automation.

Premium

$29/month for 15,000 emails

Premium adds Mailjet’s more advanced marketing capabilities.

Current Premium features include:

• advanced statistics
• visual email automation
• A/B testing
• dynamic content
• landing pages
• advanced team and account management
• 2,000 Email Previews per month
• priority support
• campaign comparison
• more advanced collaboration
• up to 20 subaccounts depending on plan configuration

Dedicated IP availability begins on eligible Premium plans at higher sending volumes, currently starting with the 100,000-email level and subject to Mailjet approval.

Custom

Custom plans are intended for higher-volume or enterprise email programs.

They can include:

• dedicated Technical Account Manager
• dedicated IP strategy
• IP performance management
• blocklist monitoring
• deliverability reports
• custom permissions
• custom subaccounts
• advanced onboarding
• deliverability consulting
• custom validations and previews

Email Editor

Mailjet provides a responsive drag-and-drop Email Editor for building campaigns and templates.

Users can create emails with visual content blocks or work directly with HTML and MJML when more control is required.

Current editor capabilities include:

• responsive email design
• reusable templates
• images
• buttons
• GIFs
• HTML blocks
• mobile preview
• Brand Kit
• AI-assisted content
• personalization
• reusable sections

Mailjet also supports MJML, which is particularly useful for developers building responsive email templates.

For teams, Premium adds real-time collaboration so multiple users can work inside the Email Editor simultaneously, leave comments, and review changes.

Email Automation

Mailjet significantly updated its automation system in 2026.

The current visual workflow builder is available on Premium and Custom plans.

Workflows can use blocks for:

• starting conditions
• sending email
• updating contact properties
• adding or removing contacts from lists
• conditions
• events
• timers
• exits

Current triggers include contact subscription, property changes, email opens and clicks, and external webhook events.

This makes Mailjet’s automation more capable than older reviews may suggest.

For example, an ecommerce business can send a purchase event from its own application to Mailjet through a webhook and use that event to trigger a personalized customer journey.

One important limitation is plan availability. Automation is not currently included in Free, Starter, or Essential.

Segmentation and Personalization

Segmentation is currently available from the Essential plan upward.

Users can build groups using:

• contact properties
• contact activity
• subscription status
• behavior
• location
• language

The current segmentation experience supports AND/OR logic and can also use Mailjet’s AI functionality to help translate audience descriptions into segmentation logic.

Premium adds dynamic content, allowing different content sections to appear for different subscriber segments.

Marketing and Transactional Email in One Platform

One of Mailjet’s strongest differentiators is that marketing and transactional email can run through the same platform.

Marketing teams can create newsletters and campaigns through the interface.

Developers can send application email through SMTP relay or API.

Common transactional use cases include:

• password resets
• account notifications
• purchase confirmations
• invoices
• shipping updates
• verification messages

Mailjet’s current Email API supports sending, contact management, statistics, templates, webhooks, senders, and domains.

Its Content API separately manages template content and related email assets.

SMTP Relay and Developer API

Mailjet provides SMTP relay for applications and systems that can send through SMTP without requiring a custom REST API implementation.

For deeper integrations, its REST APIs support programmatic email sending and management.

Mailjet currently provides:

• Send API
• Email API
• Content API
• Event API
• Parse API
• SMTP relay
• webhooks

This combination makes Mailjet particularly relevant when a company needs both a visual marketing tool and infrastructure that developers can integrate into an application.

Deliverability Tools

Mailjet provides several tools intended to support email deliverability.

Current capabilities include:

• SPF and DKIM domain authentication
• email address validation
• bounce and block handling
• sender statistics
• Email Previews
• dedicated IP options for eligible high-volume accounts
• deliverability monitoring on higher plans

Mailjet automatically blocks addresses associated with certain permanent delivery failures and exposes bounce, block, spam, and engagement information in campaign statistics.

For high-volume senders, dedicated IP addresses are available on eligible Premium 100,000+ plans after review.

A dedicated IP should not automatically be considered better. Mailjet itself notes that dedicated IPs generally make sense for consistent high-volume senders capable of maintaining their own IP reputation.

HowToBuySaaS has not independently benchmarked Mailjet inbox placement against competing providers, so we do not present a universal deliverability percentage.

Analytics and A/B Testing

Basic statistics are available on lower tiers.

Premium adds more advanced analytics such as:

• campaign comparisons
• click maps
• email-provider statistics
• advanced engagement reporting
• bot-activity filtering
• A/B testing

Mailjet’s current A/B testing allows up to 10 versions of a campaign to be compared.

This is substantially more useful for established marketing teams than a simple two-version subject-line test.

Integrations

Mailjet currently promotes more than 100 integrations across CRM, ecommerce, CMS, marketing, analytics, and developer tools.

Examples include:

• WordPress
• WooCommerce
• HubSpot
• Shopify
• Google Cloud
• automation and CRM platforms

Developers can also build custom integrations using Mailjet’s APIs.

Team Collaboration

Mailjet is particularly strong when marketers and developers need to work inside the same email platform.

Premium capabilities include:

• multi-user collaboration
• account sharing
• roles and permissions
• real-time email editing
• comments
• subaccounts

This is useful for agencies and larger organizations where one employee should not necessarily have unrestricted access to every sending domain or customer account.

Support

Support availability varies considerably by plan.

Paying customers currently receive 24/7 ticket support.

Premium customers on the 50,000-email level or higher can access chat and phone support during published weekday hours.

Free users receive ticket support during their first month.

This means businesses that require immediate phone support should check the exact plan before purchasing rather than assuming every Mailjet subscription includes it.

Who Should Use Mailjet?

Mailjet is particularly suitable for:

Small Businesses

The Free and Starter plans provide an inexpensive way to begin sending campaigns.

Developers and SaaS Companies

SMTP relay, REST APIs, transactional templates, and webhooks make Mailjet useful for application email.

Marketing Teams

The Email Editor, segmentation, AI tools, A/B testing, analytics, and automation support campaign workflows.

Agencies

Subaccounts, permissions, collaboration, and shared templates make Mailjet relevant to teams managing multiple email programs.

Businesses Sending Both Marketing and Transactional Email

This is one of Mailjet’s strongest use cases because both types of email can be managed through one provider.

Mailjet Pros

• Permanent Free plan
• Up to 6,000 free emails per month
• Marketing and transactional email in one platform
• REST API and SMTP relay

• HTML and MJML support
• Segmentation from Essential
• Advanced automation on Premium
• A/B testing with up to 10 versions
• Real-time team collaboration
• Email validation and previews
• Dedicated IP option for eligible high-volume plans
• 100+ integrations
• WordPress, WooCommerce, Shopify, and HubSpot integrations
• Advanced permissions and subaccounts on higher plans

Mailjet Cons

• Free plan limited to 200 sends per day
• Free plan limited to 1,000 contacts
• Automation requires Premium or Custom
• A/B testing requires Premium
• Mailjet branding cannot be removed on Free or Starter
• Phone and chat support require Premium 50k or higher
• Higher sending volumes can become considerably more expensive
• Paid-plan overage email charges are billed automatically
• Dedicated IP is not available on low-volume plans

Mailjet vs Mailchimp

Mailchimp is a broader marketing platform with a large ecosystem around email marketing, audience management, campaigns, and additional marketing tools.

Mailjet has a particularly strong developer angle because transactional email, SMTP relay, API sending, and marketer-facing campaigns sit together in the same product.

A business mainly focused on marketing campaigns may prefer Mailchimp’s broader marketing ecosystem.

A SaaS business or application that needs both newsletters and transactional sending should compare Mailjet carefully.

Mailjet vs MailerLite

MailerLite is particularly attractive to creators, newsletter publishers, and small businesses looking for a straightforward email marketing experience.

Mailjet offers a stronger combined marketing and developer infrastructure story through SMTP relay, transactional email, and its API.

The better choice depends on whether the organization mainly needs newsletters or also needs application-generated email.

Is Mailjet Worth It in 2026?

Mailjet is worth considering when email is both a marketing channel and part of the technical product infrastructure.

The permanent Free plan makes it easy to test the editor, API, SMTP relay, forms, and basic statistics before paying.

Starter is inexpensive at $9 per month, while Essential adds the segmentation and validation capabilities that many growing marketing teams will require.

Premium becomes substantially more capable with the new automation builder, advanced analytics, A/B testing, landing pages, and collaboration.

Its main weakness is feature gating. Several of Mailjet’s strongest marketing capabilities require Premium, and higher-quality phone or chat support is reserved for larger Premium plans.

For developers, SaaS businesses, agencies, and teams that want marketing campaigns and transactional email under one provider, Mailjet has a clear reason to be shortlisted.
