Overview
Mailjet, now operating as Sinch Mailjet, is a cloud-based email platform founded in 2010 in France and acquired by Sinch AB in December 2021 as part of a $1.9B purchase of Pathwire. It serves over 100,000 customers across 150 countries, including DHL, Microsoft, and Wikipedia. The platform bridges marketing and development teams by combining a drag-and-drop email editor, real-time multi-user collaboration, and AI-assisted content tools with a robust REST API, SMTP relay, and Parse API for transactional email workloads. Mailjet is distinguished by its European heritage, built-in GDPR compliance, ISO 27001 certification, volume-based pricing with unlimited contacts, and deliverability advisory services for enterprise senders. MJML, its open-source responsive email markup language, adds a developer-community dimension.
Sinch Mailjet is a dual-purpose email platform offering both a marketer-friendly drag-and-drop campaign tool and a developer-grade email API/SMTP infrastructure, designed for teams that need to collaborate across marketing and engineering on transactional and marketing email programs at scale.

Alternatives in Transactional Email & Developer Email APIs6
Mailjet occupies a hybrid position as both a developer-grade email API platform and a marketer-friendly campaign tool, targeting teams that need both capabilities under one roof.
- Its European origin and deep GDPR compliance posture differentiate it from US-centric API-first competitors (Mailgun, SendGrid, Resend).
- Compared to pure developer tools it adds real-time multi-user collaboration, a drag-and-drop editor, and landing pages; compared to marketing-only platforms it offers robust REST APIs, SMTP relay, MJML, and webhook infrastructure.
- Volume-based pricing with unlimited contacts distinguishes it from contact-count-priced rivals.
- Within the Sinch portfolio it complements Mailgun (developer-first) by serving the marketer-plus-developer buyer segment.

- Strong email deliverability
- Built-in GDPR compliance
- Easy API integration and good documentation
- Unlimited contacts on most paid plans
- Quick setup and onboarding
Criticized

- Small template library
- UI lag and platform performance issues
- Inaccurate analytics reported via SMTP
- Free plan 200 emails/day cap reached too quickly
Mailjet receives generally positive scores for ease of use, affordability, and deliverability reliability. G2 reviewers (4.0/5, 171 reviews) highlight the intuitive drag-and-drop editor, GDPR-compliant setup, and real-time collaboration as standout features. Capterra users (4.2/5, 447 reviews) echo praise for cost-effective pricing and quick setup, while criticism centers on customer support responsiveness, account suspension practices, and limited automation depth. A recurring negative theme across both platforms involves accounts being suspended without advance notice or clear communication, which reviewers describe as a reliability and trust concern for business-critical sending.
Pricing
Free plan: $0/month, 6,000 emails/month with 200 emails/day cap and 1,000 contacts.
- Starter
$9/month, 8,000 emails/month, 2,000 contacts, no daily cap. Essential: $17/month, 15,000 emails/month, unlimited contacts, segmentation, AI content, email validation credits, no Mailjet logo.
- Premium
$27/month, 15,000 emails/month, adds automation, landing pages, advanced statistics, bot-activity filtering, and priority support (dedicated IP available on 100k+ plans). Custom/Enterprise: custom pricing with dedicated Technical Account Manager, IP strategy, blocklist monitoring, deliverability reports, and SLA. Volume scales up through the pricing slider; annual plans receive a 10% discount. Overage emails are billed per additional 1,000 sends. Unused credits do not roll over.
Limitations
- Automation is restricted to four trigger types with no if/then open/click conditional branching; live journeys cannot be edited without duplicating and replacing them.
- Automation builder is gated to the Premium tier, not included in Essential.
- The template library is relatively small (70+ templates).
- The free plan caps sends at 200 emails per day.
- Customer support quality is a recurring complaint across Capterra and G2 reviews, with users citing slow response times, scripted replies, and abrupt account suspensions without advance notice or clear explanation.
- UI performance (spinner/lag) and analytics accuracy issues (incorrect stats via SMTP) are also noted by users.
- Image storage capacity is described as limited.
