Notifuse

About Notifuse

**Notifuse** is a modern, open-source emailing platform designed as a self-hosted alternative to Mailchimp, Brevo, Klaviyo, and other commercial email marketing services. Built with Go and React, Notifuse enables organizations to send newsletters and transactional emails at a fraction of the cost by eliminating per-subscriber and per-email pricing. With 1.4k+ GitHub stars and active development, the platform provides enterprise-grade features—visual email builder, A/B testing, contact segmentation, transactional API, and multi-workspace support—while keeping all data on your own infrastructure. Licensed under AGPL v3.0, Notifuse is ideal for developers, agencies, and privacy-conscious organizations seeking complete control over their email communications. **Category:** Email Marketing / Newsletter Management / Transactional Email / Self-Hosted Tools / Marketing Automation **Webstudio Integration:** Notifuse integrates with Webstudio through its **REST API and webhook system**. **Subscription forms:** Build custom signup forms in Webstudio using HTML Embed or form components, then POST directly to Notifuse's API endpoints to add contacts to lists with custom fields. Use Liquid templating variables like {{ contact.first_name }} to personalize welcome emails automatically triggered upon subscription. **Transactional emails:** Connect Webstudio forms to Notifuse via automation platforms (n8n, Zapier, Make)—form submission triggers → process data → send transactional email via Notifuse API using pre-defined responsive templates. **Webhook events**:Notifuse sends real-time webhooks for opens, clicks, bounces, and unsubscribes that can trigger actions in your Webstudio-connected workflows. For agencies managing multiple client sites, Notifuse's workspace architecture allows isolated email campaigns per Webstudio project with custom sending domains. **Strengths:** **No per-email or per-subscriber fees**—self-host unlimited contacts and campaigns for only infrastructure + email delivery costs (\~$1 per 10,000 emails via AWS SES). Modern visual email builder with drag-and-drop MJML components, real-time preview, and Liquid templating for dynamic personalization. Built-in A/B testing for subject lines, content, and send times. Real-time contact segmentation with dynamic rules and relative date filters (e.g., "opened email in last 7 days"). Rich contact profiles with complete activity timeline: messages, profile changes, webhook events, subscription changes. Powerful transactional API with responsive templates for perfect rendering across devices. Multi-provider support: Amazon SES, Mailgun, Postmark, Mailjet, SparkPost, and generic SMTP. S3-compatible file manager with CDN delivery for images and attachments. Multi-tenant workspaces with custom domains—perfect for agencies managing multiple clients. Granular user permissions with role-based access control. Notification center for self-service subscription management. Open/click tracking with detailed analytics. Clean architecture with Go backend (fast, efficient) and React/TypeScript frontend. Interactive setup wizard for quick deployment. Active development with 64+ releases. **Weaknesses:** Relatively new project (fewer stars and community resources compared to Listmonk's 15k+ stars). **Automations feature is "Coming Soon"**—event-driven workflows not yet available, limiting automated sequences like welcome series or drip campaigns. Requires technical knowledge to self-host (Docker, server administration, database management). No built-in SMTP—must configure external email delivery provider. Smaller community means fewer tutorials, templates, and third-party integrations compared to established platforms. AGPL v3.0 license requires source code disclosure if modified and deployed as a service (may concern some enterprises). Documentation still maturing compared to longer-established alternatives. No native SMS or multi-channel support (email only). Enterprise pricing not published—requires direct contact. **Pricing:** - **Forever Free (Self-hosted):** Completely free under AGPL v3.0 license - Unlimited subscribers - Unlimited campaigns - All features included - Multi-workspace support - Pay only for: hosting ($5–20/month VPS) + email sending (\~$1 per 10,000 via AWS SES, Mailgun, Postmark, etc.) - **Enterprise:** Custom pricing with dedicated support - Priority support - Custom implementation assistance - Training & onboarding - SLA guarantee - Contact: [](mailto: **Cost comparison:** A business with 50,000 subscribers sending 200,000 emails/month would pay \~$400+/month on Mailchimp or ~~$150/month on Brevo. With Notifuse self-hosted on a $10/month VPS plus AWS SES (~~$20 for 200k emails), total cost would be approximately **$30/month**—a 90%+ savings while maintaining complete data ownership and privacy.
