About Mailjet

Mailjet is a French email service, now owned by Sinch, that covers both marketing campaigns and transactional email through an API and SMTP relay. Its marketing side has a drag-and-drop editor with templates, contact lists and segmentation, sign-up forms, A/B testing, simple automation and AI writing help. A distinctive feature is real-time collaboration: several team members can work on the same email with comments, roles and approval steps, and agencies can use subaccounts. It is GDPR-focused, with data hosted in Europe. Pricing is based on monthly email volume rather than contacts: a free plan allows a daily-capped number of emails, and paid Starter, Essential and Premium tiers remove the daily limit and Mailjet branding and add features like segmentation and automation. Automation is basic compared with ActiveCampaign or Klaviyo, and support on lower tiers is limited. It suits teams that send both product and marketing email from one account.

Best for: Teams that need marketing and transactional email together, with collaborative editing.
