What is email validation?

Email validation is the process of verifying that an email address is properly formatted and follows standard email syntax rules. A valid email consists of a local part (before the @), the @ symbol, and a domain part (after the @). Email validation checks ensure addresses meet RFC 5322 specifications, helping prevent typos, catch formatting errors, and reduce bounced emails in applications, forms, and databases.
