Free Email Validator and Email Address Parser
This free email validator helps you check whether an email address has a valid format, inspect the local part and domain, and generate a clean mailto link for forms, CRMs, or support workflows. It is useful when you need fast client-side validation without sending addresses to a third-party API.
The tool also works as an email parser, showing you the normalized address, top-level domain, plus alias, and a best-effort provider guess for Gmail, Outlook, Yahoo, iCloud, Proton, and custom domains.
Common use cases for email validation
- Check whether a signup form email looks syntactically valid before submission
- Inspect plus addressing like
name+tag@gmail.comfor routing or filtering logic - Generate safe mailto links for contact buttons, support portals, and dashboards
- Review custom domain email addresses before importing leads or user records
FAQ
Does a valid format mean the mailbox exists?
No. This tool validates format and structure only. Real deliverability still depends on DNS, MX records, mailbox existence, and SMTP acceptance.
Does the validator send my email to a server?
No. All checks run entirely in your browser, so the email address stays on your device.
