Overview
Mailjet is an email marketing and email delivery service operated by Sinch. It combines campaign design and sending with contact management, analytics, automation, a Send API, SMTP relay, and event webhooks.
Its published plans scale by sending volume and include different contact allowances and feature sets. This model can suit teams that need campaign email and application-triggered messages in one service, but buyers should account for daily limits, overages, and expiring credits.
