About Us
Protecting inboxes, one email at a time
We started Mailchk because we were frustrated by the lack of affordable, reliable email validation tools. Our mission is to help businesses of all sizes protect their platforms from fake signups and disposable emails.
Our Story
Mailchk was born out of frustration. As developers building SaaS products, we constantly dealt with fake signups, trial abuse, and inflated user metrics caused by disposable emails.
Existing solutions were either too expensive for startups or lacked the accuracy we needed. So we built our own—a fast, affordable, and accurate email validation API that any developer can use.
Today, Mailchk protects thousands of applications from disposable and temporary emails, helping businesses maintain clean user bases and healthy sender reputations.

Our Values
Speed First
Every millisecond counts. We obsess over performance so your users never have to wait.
Fair Pricing
Enterprise-grade validation shouldn't cost enterprise-grade prices. We keep our pricing honest and accessible.
Privacy Focused
We don't store or sell your data. Emails are validated and forgotten—your users' privacy is protected.
