Inframail

A bootstrapped cold outreach infrastructure platform that handles the technical complexity of sending cold emails at scale — domain setup, email deliverability, and inbox management for sales teams and agencies. Built without venture funding, the platform grew by solving a persistent, unglamorous problem that every outbound sales operation faces but few want to manage themselves. Operating on a subscription model, it now generates $50k per month in recurring revenue, demonstrating that essential B2B tooling with strong retention can quietly build a highly profitable business.
