In the B2C market Email Checker stands out with its unique ability to fully verify Yahoo and Ymail email addresses. These are essential for any serious site that collects consumer email addresses. Many providers claim to verify Yahoo but they are not actually doing so with great accuracy, unlike Email Checker.

Companies that use Email Checker include RIPE,, McAffee and ABC.

The typical use for Email Checker is to verify emails as they are collected on a website. With so many websites using email as username and primary contact, the need to ensure good quality email addresses is paramount.
