Mailjet

Mailjet covers both sides of business email. Marketing teams design newsletters and campaigns in a drag-and-drop editor, segment their audience, run A/B tests, automate sequences and follow results, with several people able to work on the same template. Developers send transactional messages such as receipts and password resets through a REST API or SMTP relay, with SDKs for common languages and webhooks for delivery events. An AI Email Generator drafts subject lines, copy and layout from a prompt. The service was founded in France, emphasizes deliverability and GDPR compliance, and is now part of Sinch. It is used by small businesses, agencies and product teams.
