The open-source alternative to Mailchimp, Brevo, Mailjet, Listmonk, Mailerlite, and Klaviyo, Loop.so, etc.

Notifuse is a modern, self-hosted emailing platform that allows you to send newsletters and transactional emails at a fraction of the cost. Built with Go and React, it provides enterprise-grade features with the flexibility of open-source software.

• Visual Email Builder: Drag-and-drop editor with MJML components and real-time preview
• Campaign Management: Create, schedule, and send targeted email campaigns
• A/B Testing: Optimize campaigns with built-in testing for subject lines, content, and send times
• List Management: Advanced subscriber segmentation and list organization
• Contact Profiles: Rich contact management with custom fields and detailed profiles

• Visual Flow Builder: Build multi-step journeys on a canvas — each automation is a graph of nodes with a single trigger as its root
• Node Types: delay, email, branch, filter, add_to_list, remove_from_list, ab_test, webhook, and list_status_branch
• Timed Delays: Wait minutes, hours or days between steps
• Branching & Filters: Split a journey on contact conditions, or on a contact's status in a given list
• A/B Testing In-Flow: Weighted variants inside an automation, not just on broadcasts
• Webhook Steps: Call an external URL mid-journey, with retry budget
• Enrollment Control: Enroll a contact once or every_time the trigger fires, with optional exit_on_reply
• Per-Contact State: Every enrollment tracks its own status (active, completed, exited, failed) and current node, with a per-node history (entered, processing, completed, failed, skipped)
• Draft / Live / Paused: Edit safely, then publish — paused automations hold their enrollments

• Easy Setup: Interactive setup wizard for quick deployment and configuration
• Transactional API: Powerful REST API for automated email delivery
• Webhook Integration: Real-time event notifications and integrations
• Liquid Templating: Dynamic content with variables like {{ contact.first_name }}
• Multi-Provider Support: Connect with Amazon SES, Mailgun, Postmark, Mailjet, SparkPost, SendGrid, and SMTP

• Open & Click Tracking: Detailed engagement metrics and campaign performance
• Real-time Analytics: Monitor delivery rates, opens, clicks, and conversions
• Campaign Reports: Comprehensive reporting and analytics dashboard

Privacy-first, cookieless web analytics built in — the Staminads feature set merged into Notifuse, running entirely on PostgreSQL (no ClickHouse, no extra services):

• Engaged-time sessions: sessions measure real visible/focused time (TimeScore), not wall-clock guesses; bounce rate is engagement-based
• Channel attribution: 40 default rules classify traffic (paid click-ids like gclid/fbclid, organic search, social, email) — fully editable per workspace, with one-click backfill of historical data when rules change
• Goals & custom dimensions: conversion tracking with values and properties, plus 10 custom dimension slots (custom_1..custom_10)
• Cookieless & GDPR-friendly: no cookies, no visitor fingerprinting, IPs used only for optional geo lookup and never stored
• Lightweight SDK: ~21 KB gzipped script served by your own Notifuse instance (/na.js); the user agent is parsed in the browser, so the raw string is never sent to the server
• Setup: enable Web Analytics on a workspace, paste the snippet from its settings page, done. Country, region and city come from the MaxMind GeoLite2 City database shipped in the image at /app/geoip/GeoLite2-City.mmdb — to keep it fresher, drop your own copy into the mounted data/ directory as GeoLite2-City.mmdb (it takes precedence) or set GEOIP_DB_PATH (see geoipupdate). This product includes GeoLite2 data created by MaxMind, available from maxmind.com
• Data retention: every session is kept for as long as you keep it. Monthly partitions (web_sessions_y2026m08 and its web_pages_* / web_goals_* siblings) are created automatically, and expiring old data is a deliberate DROP TABLE on the partitions you no longer want — instant, and the disk comes back immediately
• Scale path: data lives in monthly-partitioned tables per workspace; heavy-traffic installs can run AlloyDB Omni via compose.alloydb.yaml and get columnar-engine acceleration for dashboard queries with zero schema changes
• Requirements: PostgreSQL 17 or newer (the shipped compose file stays on 17 — upgrading a major version needs pg_upgrade, and PostgreSQL 18 also changed its data directory layout)

• S3 File Manager: Integrated file management with CDN delivery
• Notification Center: Centralized notification system for your applications
• Responsive Templates: Mobile-optimized email templates
• Custom Fields: Flexible contact data management
• Workspace Management: Multi-tenant support for teams and agencies

Notifuse follows clean architecture principles with clear separation of concerns:

• Domain Layer: Core business logic and entities (internal/domain/)
• Service Layer: Business logic implementation (internal/service/)
• Repository Layer: Data access and storage (internal/repository/)
• HTTP Layer: API handlers and middleware (internal/http/)

• Console: Admin interface built with React, Ant Design, and TypeScript (console/)
• Notification Center: Embeddable widget for customer notifications (notification_center/)

• PostgreSQL: Primary data storage with Squirrel query builder

Issues, on the other hand, are very welcome and are the best way to help:

• Report a bug — steps to reproduce, your version, and what you expected instead
• Request a feature — describe the problem you're trying to solve rather than a specific implementation
