Frequently Asked Questions

Does this validate all valid emails?

This pattern catches most valid emails but the official email spec (RFC 5322) allows unusual characters. For production, consider also checking the domain exists.

What regex flavor does this use?

This tester uses JavaScript regex (ECMAScript). Most patterns work the same in Python, Java, and other languages.
