Notifuse

Notifuse is a self-hosted emailing platform designed for teams and businesses seeking cost-effective alternatives to commercial email services. It supports both newsletter campaigns and transactional emails with a visual drag-and-drop editor using MJML components, real-time preview, and Liquid templating for personalization. The project describes itself as an open-source alternative to Mailchimp, Brevo, Mailjet, and similar platforms.

Key capabilities include contact management with custom fields and activity timelines, A/B testing for subject lines and send times, real-time open and click tracking, automation workflows with branching and delays, a transactional API for programmatic sending, and subscriber preference management. Built with Go and React, it offers both self-hosted deployment and managed cloud hosting starting at $16/month.
