Email Validation With Regex: Keep It Simple

The "perfect" email regex doesn't exist: the full rules allow quoted local parts, comments and international domains. A simple pattern catches typos; only a confirmation email proves an address works.

A practical pattern

^[^\s@]+@[^\s@]+\.[^\s@]+$

Better than a bigger regex

• Use <input type="email"> for a built-in browser check and the right mobile keyboard.
• Don't reject + tags or long new domains like .photography.
• Send a confirmation link: it's the only real test.
