Najczęściej zadawane pytania

Can regex fully validate an email address?

Not perfectly. The official email specification (RFC 5322) is extremely complex. Simple regex patterns cover 99% of real-world emails. For complete validation, use a dedicated email validation library or simply send a confirmation email.
