Why We Started Building Email Checker

For years, we have worked closely with businesses of all sizes and built multiple companies across both e-commerce and B2B SaaS. Through every stage of this journey, one channel consistently proved its value: email.

Whether it’s transactional messages that keep operations running, marketing campaigns that drive revenue, or cold outreach that opens new doors — email has always been the most reliable and cost-effective growth channel.

The Real Challenge: Deliverability and Reputation

Anyone who takes email seriously quickly realizes that deliverability and sender reputation are critical. Poor list quality, high bounce rates, and user complaints can destroy a sender’s reputation overnight. When that happens, even the best email content ends up buried in spam or stuck in promotions — invisible to the people who matter most.

Over the years, we became deeply familiar with every aspect of email performance. We tested countless approaches, optimized content and infrastructure, and used a wide range of tools. Some were excellent. But many were either prohibitively expensive, frustratingly slow, or simply unreliable at scale.

One area in particular consistently failed to meet our standards: email verification. Whether in bulk or through APIs, the existing solutions forced us to choose between two bad options — fast but overpriced, or affordable but inaccurate and unreliable. Neither worked for our needs.

Why We Decided to Build Our Own

Instead of settling, we decided to build the solution we wished existed.

We started by developing our own email verification API, not as a side project, but as a core infrastructure component for our own startups. We rigorously tested it on over 100,000 real emails, validating accuracy through actual delivery results rather than theoretical benchmarks. The outcome was clear: our system consistently outperformed established providers in both speed and accuracy.

Once we proved the technology in real production environments, the next step was obvious. We turned it into a SaaS product so others could benefit from the same reliability, performance, and cost-efficiency.

Our Mission

This is how Email Checker was born — not from a pitch deck, but from real operational pain, extensive experience, and a drive to build something genuinely better.

Our mission is simple:
To provide fast, accurate, and affordable email verification that meets the demands of serious senders. And this is just the beginning.
