Adrian Norman

As a dedicated product developer with extensive experience in software architecture and automation, I specialize in building robust tools that enhance data integrity and streamline digital workflows. In today’s digital landscape, ensuring the quality of user data is paramount for any freelancer or business owner to maintain high deliverability and prevent fraudulent activities.

My primary focus is providing high-performance solutions for email validation and security. One of my core projects is the Sonjj API Center, which hosts the Ychecker tool—a specialized API designed for comprehensive email verification. This solution is particularly valuable for developers and marketers who need to validate user identities or clean large mailing lists with precision.

The Ychecker email verification API operates via a streamlined GET /v1/check_email/ endpoint. By integrating this API, users can instantly determine the existence of an email address, identify disposable providers, and classify email types. A unique feature of this service is its ability to detect whether a Gmail account requires phone verification for login, providing an extra layer of security insight that most standard validators miss.
