Regex Editor & Tester

Validates email addresses belonging specifically to the nter.es domain. The local part (before @) accepts one or more lowercase letters, digits, dots, underscores, percent signs, plus signs, or hyphens, but no uppercase letters are allowed. With the global and multiline flags enabled, it can validate multiple email addresses across separate lines in a single pass. Typically used in Spanish-language applications to restrict registrations to a specific organization's domain.
