About

Stop Wasting Time on Bad Email Data. Real-Time Email Validation - Cut Bounce Rates, Eliminate Disposables and Plug Funnel Leaks.

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.

Pros & Cons from Real Users

Pros

  • Before using this product my company was having trouble with fraudulent and disposable email attacks. We needed a solution that could check and filter out in real-time invalid and disposable email signups as they were ruining our CRM data quality. After implementing Byteplant's Email Validator API I can confidently say that >95% of all bad emails have been eliminated - thanks!!
  • From the email validation services I've tried, Byteplant's Email Validator has been the most accurate.

Cons

  • In the beginning the API did not keep up with the speed of email signups when we were under attack. However, I contacted their support and the rate limit was quickly adjusted to better fit our needs.
  • Nothing to dislike, good service, easy to use and to integrate into your CRM platform.
