Visión general de la herramienta

The Email Validator performs a strict client-side syntax check designed for practical form validation and lead hygiene workflows. It normalizes casing and surrounding whitespace, verifies there is exactly one @ symbol, checks local-part rules, and enforces domain label constraints with a real top-level domain segment. This helps you catch obvious typos such as missing dots, repeated dots, invalid characters, and malformed hostnames before they reach your backend. Validation runs entirely in your browser, so email input stays private.

Preguntas frecuentes

Does this check if the mailbox actually exists?+

No. It validates email syntax only. Mailbox existence requires SMTP or verification-email workflows on your backend.

Does normalization change deliverability?+

Lowercasing and trimming are safe for most workflows and improve consistency. Some providers treat local-part casing as equivalent, but preserving the user-entered value in storage can still be useful for auditing.

Why can a valid-looking address still bounce later?+

Syntax validity only means the format is correct. Bounces can still happen from inactive inboxes, blocked domains, disposable providers, or full mailboxes.
