Mailjet, now part of Sinch, is an email platform that unifies marketing campaigns and transactional email, so growing businesses can manage newsletters and system emails in one account.
Mailjet’s strength is covering both sides of email. Marketers get Passport, a drag-and-drop campaign editor with real-time collaboration — teammates can comment and edit simultaneously — plus segmentation, automation workflows on Premium, A/B testing and landing pages. Developers and product teams get a full email API, SMTP relay and webhooks for transactional messages like receipts and password resets, with deliverability tooling and optional dedicated IPs at higher volumes. Pricing scales with emails sent rather than contacts stored, which favors large lists with moderate send frequency.
Mailjet was founded in France in 2010 and still emphasizes European compliance: it is ISO 27001 certified, GDPR-aligned and offers EU data handling options, which makes it a common choice for companies wary of US-only vendors. Teams can manage multiple brands or clients through subaccounts, lock sections of a template so designs cannot be broken by editors, and control user permissions in detail. Even the free plan includes the template library, a form builder and basic statistics, and the same account can add SMS sending in supported countries.
The Free plan includes 6,000 emails per month (200/day) and 1,000 contacts. Starter is $9/month, Essential $19/month and Premium $29/month at 15,000 emails, with prices scaling as volume grows; annual billing saves 10%.
Growing businesses, startups and product teams that want marketing and transactional email under one roof, with strong collaboration features and developer-friendly sending infrastructure.
