Mailjet launched in France in 2010 with a focus on making email collaboration easier for teams. Today it serves over 100,000 customers across 150 countries. Now part of the Sinch group (following the Pathwire acquisition in 2021), it covers both marketing campaigns and transactional email through a single account.
In this Mailjet review, a few things stand out: volume-based pricing that doesn’t penalize you for list size, real-time co-editing built into the campaign builder, and deliverability tools that most platforms either charge extra for or don’t include at all.
My experience with Mailjet
Getting started takes slightly longer than you’d expect. Before you can launch your first campaign, Mailjet’s support team runs a verification check on your business details and intended sending volume. It’s a minor but noticeable friction point compared to platforms that let you start sending immediately after signup.
Once your account is active, the experience is organized and straightforward. The dashboard separates campaign tools, API settings, and contacts into clearly labeled sections, and the onboarding guide forks into different paths depending on whether you’re setting up as a marketer or a developer.
Value for money is strong, especially on the Essential plan, where unlimited contacts and access to deliverability tools make the $17/month price point hard to argue with.
Mailjet review: Features
Mailjet’s standout feature is its real-time collaborative editor. Multiple users can work on the same campaign at once, leave inline comments, and lock individual sections to prevent unintended edits. For teams that typically bounce email drafts around over Slack or shared folders, this alone is a meaningful upgrade. It’s an unusual capability at this price range.
Beyond collaboration, the platform covers both marketing and transactional email through a shared API infrastructure. The MJML-based editor generates responsive layouts automatically, and A/B testing supports up to 10 campaign variations, which is one of the more flexible implementations we’ve come across. The Brand Kit, which can generate your visual identity from a website URL, speeds up template setup and keeps designs consistent across sends.
Where Mailjet trails the field is automation. The workflow builder handles standard drip sequences and basic triggers, but it doesn’t support the behavioral conditions or multi-path journeys that tools like ActiveCampaign or Brevo offer. The template library (around 65 designs) is functional but limited in variety. There’s also no built-in landing page builder, which some competitors include as standard.
Mailjet review: User experience
The interface is clean and logically laid out.
Campaign creation follows a clear progression: pick a template, edit in the drag-and-drop builder, select your recipients, and schedule. Non-technical users should find the flow intuitive from day one, and the editor works well for standard newsletter and promotional campaigns without needing any code knowledge.
A few details worth knowing: Mailjet automatically applies dark mode CSS and meta tags to your emails, which prevents the broken-layout issues that affect many campaigns in dark-mode inboxes. The Brand Kit also makes it faster to stay on-brand across multiple campaigns without manually re-entering colors and fonts each time. The overall UI is functional, though it feels less modern than newer platforms, and some sections look like they haven’t been refreshed in a while.
Mailjet review: Customer support
Support access is tiered by plan, and the lower tiers are restrictive. Free and Starter subscribers get online support for the first month only; after that, you rely on Mailjet’s documentation center and its self-serve Email Academy. Essential and Premium customers retain ongoing access to online support, which is a step up but still falls short of live chat options offered by some rivals.
Custom enterprise customers receive a dedicated Technical Account Manager plus an API expert, which is a meaningful upgrade for high-volume senders. For a platform that serves developers and teams running critical email infrastructure, the gap in support between entry-level and enterprise plans is wide enough to matter. If deliverability issues arise on a lower-tier plan, your path to resolution is mostly self-service.

Mailjet’s pricing model is one of its clearest advantages over contact-capped competitors. Because Essential and Premium charge by email volume rather than contacts stored, businesses with large but infrequently mailed lists get considerably better value than they would on Mailchimp or Klaviyo.
The free plan covers 6,000 monthly sends with a 1,000-contact cap and a 200-per-day limit. Starter at $9/month removes that daily cap but tops out at 8,000 emails per month with no way to scale it further, making it a transitional tier rather than a long-term home. Essential at $17/month is where the platform opens up: unlimited contacts, 500 email validations, 500 email previews per month, and volume scaling from 15,000 to 500,000 sends.
Premium at $27/month adds expanded preview credits, team and account management tools, and a dedicated IP on plans with 100,000+ sends, with the same volume range. Annual billing reduces Essential to $15.30/month and Premium to $24.30/month. For senders above 500,000 emails, a Custom enterprise tier is available with dedicated support and tailored terms. All prices listed are in USD and exclude VAT where applicable.

Buy it if…
- You manage email with a team. The real-time co-editing and granular permission controls speed up campaign production in a way most platforms don’t match at this price. If your team currently passes drafts around over email or Slack, this feature alone justifies the switch.
- Your contact list is large but you don’t email often. Because you pay for sends rather than contacts stored, Mailjet is significantly cheaper for businesses that maintain big lists but only campaign occasionally.
- You need marketing and transactional email in one place. A shared API infrastructure means your developers and marketers aren’t managing separate tools or reconciling sender reputations across two platforms.
Don’t buy it if…
- Advanced automation is central to your strategy. The workflow builder covers basic scenarios, but behavioral triggers, complex segmentation, and multi-path journeys require a platform like ActiveCampaign or Brevo.
- You want a wide template selection. Around 65 designs is enough for straightforward campaigns, but it’s a thin library compared to what Mailchimp offers, and design variety leans minimal.
Also consider
- Brevo: This platform has volume-based pricing like Mailjet’s but with more capable automation, SMS support, and a more polished interface. A natural comparison for teams weighing their options.
- MailerLite: Worth a look if landing pages, digital product sales, or a more contemporary design experience matter to you, alongside solid email tools.
- ActiveCampaign: Stronger choice if sophisticated marketing automation and integrated CRM are non-negotiable.
How I tested Mailjet
- Signed up for a Mailjet account and completed the onboarding flow for both marketer and developer setup paths.
- Built and sent test campaigns using the drag-and-drop editor, A/B testing tool, and automation builder across free and paid tiers.
- Reviewed official pricing documentation alongside user feedback from major review platforms.
For this Mailjet review, testing focused on the features a typical small business or marketing team uses day to day: campaign creation, contact management, collaboration tools, and the analytics available on standard plans. I also assessed the setup experience, support quality at each tier, and how the platform compares against competitors at a similar price point.
