Email Address Validator & Parser

Type or paste an email address and see whether it's well-formed, what's in each part (local, domain, plus-tag, TLD), and a soft verdict — role-based, disposable, or a likely typo. Bulk mode accepts one address per line and renders a copyable table. All checks run in your browser; nothing is uploaded.

Notes

  • All checks are structural. We cannot run DNS lookups from a browser, so we cannot tell you whether the mailbox actually exists. Use this tool to catch typos and validate the format; use a transactional-send step (welcome email) for full deliverability.
  • +tag addressing is preserved — alice+filter@gmail.com is treated identically to alice@gmail.com at Gmail, so we don't flag it as suspicious.
  • The role-based list is curated: admin, postmaster, abuse, noreply, info, support, and a few dozen other common department / operator addresses. We never reject them; we just flag them so a CRM import can route them.
  • The disposable-domain list is intentionally short. The long tail of throwaway providers changes weekly and we don't chase it; the names in this list are the providers with real consumer traffic.
