SaaS Email Marketing Platform (Mailchimp-Like) Built with Laravel & React
A full-featured, scalable email marketing SaaS built with Laravel, PHP 8.2, React, and Inertia.js, enabling businesses to create campaigns, manage subscribers, automate sending, and track performance—all within a modern, high-performance architecture.

Many small and mid-sized businesses struggle with expensive or overly complex email marketing tools. I set out to design and build a Mailchimp-like SaaS platform that delivers core email marketing capabilities while remaining flexible, extensible, and cost-efficient.
The result is a production-ready system designed with scalability, reliability, and analytics at its core.
