MailFlow is a fully built, multi-tenant email marketing SaaS platform powered by Amazon SES. It is not a side project or MVP it is a production-grade platform with 15 complete feature modules covering the entire lifecycle of an email marketing business, from tenant onboarding through to campaign analytics. The buyer inherits a warmed Amazon SES account, a live AI campaign assistant, a complete billing system supporting both card and crypto payments, and a fully Dockerized deployment stack ready to go live on any Server.

The Core Problem It Solves:
Email marketing tools like Mailchimp and Klaviyo charge per contact or per email sent at scale. MailFlow lets you run your own white-label email marketing platform charging your own tenants your own prices while keeping delivery costs near-zero on Amazon SES ($0.10 per 1,000 emails). This is a platform you can sell to agencies, e-commerce stores, newsletters, and SMBs who want their own managed email marketing tool.

Admin if this is not allow here please let me know.

NB: You might be wondering "Why sell this instead of just hosting it and making money yourself?" That's a fair question. The honest answer is that I have other projects in the pipeline that require funding, and this is how I'm making that happen. What I can tell you is that whoever acquires this gets more than just the code. I will provide full hands-on support post-sale to help you modify and adapt the platform to fit your specific use case. Updates can be rolled out in batches, and I am committed to supporting you for as long as you are actively managing the project. You're not buying code and getting dropped. You're getting a builder who stays in your corner.
