Kling is a self-hosted email marketing platform that lets you run campaigns, build automation workflows, segment audiences, and track attribution while keeping full control of your customer data. It deploys via Docker and uses MongoDB with BullMQ for job scheduling.
Core capabilities: - Visual workflow builder for abandoned cart recovery, win-back campaigns, and post-purchase sequences - Multi-channel messaging (email, SMS, WhatsApp, push notifications) - Last-touch and multi-touch attribution tracking - Customer segmentation with purchase history and engagement data - Template management with personalization variables - Real-time deliverability monitoring (sent, delivered, opened, clicked, bounced)
I started this project because existing marketing automation tools either lock you into their infrastructure or cost too much for small teams. We're giving businesses the choice to self-host and own their data.
The platform is built for e-commerce stores, engineering-led teams, and privacy-conscious organizations that want control over their marketing stack.
I'd value feedback on: - Architecture choices (MongoDB + BullMQ for job scheduling) - Deliverability infrastructure for self-hosted setups - Automation workflow UX and trigger logic - Attribution model implementation
