About

UserCheck is a real-time email validation API that detects and blocks disposable, temporary, and suspicious email addresses and domains so tools can focus on genuine users and reduce fake sign-ups and abuse. It verifies whether an email or domain is valid, active, and trustworthy, checks domain reputation, identifies public email providers, relays, role accounts, and offers smart suggestions for common typos, syntax validation, and bulk processing of large lists. UserCheck continuously updates its disposable email database and enhanced validation rules, and it integrates seamlessly via a simple REST API with predictable JSON responses for efficient, low-latency verification workflows. It scales to handle high volumes of requests without performance degradation and offers organizational features like environment separation for development, staging, and production workflows. Additional capabilities include custom blocklists, webhooks, and integrations with tools.
