Prevent fake signups with a 5-minute email validation API

Prevent fake signups with a 5-minute email validation API targets a $150M = 250,000 SaaS and web apps with signup flows x $600 ARPA (api tier avg per year) total addressable market with medium saturation and a year-over-year growth rate of 12-18% indicative growth for verification and anti-fraud tooling.

Key trends driving demand: rise-of-disposable-email-services -- more throwaway providers means higher false signup rates and greater demand for detection; api-first-developer-tooling -- teams prefer quick SDKs and low-latency APIs that fit CI/CD and serverless stacks; focus-on-email-deliverability -- teams are motivated to reduce fake signups to protect sender reputation and deliverability; automation-and-bot-fraud -- increasing bot sophistication raises cost of manual mitigation and boosts demand for automated checks.
