About MailCull

Email verification SaaS with an AI layer that explains every result in plain English instead of returning a status code nobody can question. Live product, paying customer, Paddle billing, runs on $15/month. The hard part is done: verification engine, API, 10 free tools that pull traffic, 77 SEO posts already indexed. What's missing is marketing. I spent 5 months building and about 2 weeks selling. The $19 MRR reflects that, not the product. Priced for someone who'd rather market than build.
