Regex Editor & Tester

This regex validates basic email addresses by matching a local part (alphanumeric characters plus ._%+-), an @ symbol, a domain name, and a 2-3 character lowercase top-level domain. It's commonly used for simple form validation to ensure users enter properly formatted email addresses. The pattern has limitations with newer longer TLDs like .photography or .technology, and doesn't enforce strict RFC compliance, making it suitable for basic rather than comprehensive email validation.
