Email Verifier

Verify whether an email address is real and can receive mail. Checks syntax, MX records, disposable and role addresses, and probes the mailbox itself — then tells you if it is deliverable, risky, or undeliverable.

Free Email Verifier — Check If an Email Address Is Real

This email verifier checks whether an email address actually exists and can receive mail, not just whether it looks right. Paste any address and the tool runs a layered set of checks in seconds, returning a clear verdict: deliverable, risky, or undeliverable. It is the fast way to verify an email address before you send to it, add it to a list, or accept it at signup.

How email verification works

Plenty of tools only do syntax validation — they confirm an address is shaped like name@domain.com and stop there. That catches typos but nothing else: a perfectly formatted address can still bounce because the mailbox never existed. A real email validator goes further, and this tool runs four layers of checks:

  • Syntax — confirms the address follows email formatting rules (local part, @, valid domain).
  • MX records — looks up the domain's DNS to confirm it actually has mail servers configured to receive mail.
  • Disposable & role detection — flags throwaway domains (10-minute-mail style) and shared role addresses such as info@, support@, or admin@ that often shouldn't go into a contact list.
  • Mailbox check — probes the mail server to see whether the specific mailbox exists, returns not found, or sits behind a catch-all domain that accepts everything.

Reading the result

The top-line status is your answer at a glance. Deliverable means the address passed every check and a real mailbox was confirmed. Risky means it is technically accepted but uncertain — typically a catch-all domain, a role address, or a disposable provider. Undeliverable means a check failed hard, for example no MX records or a mailbox that does not exist. Each result also carries a confidence label: verified (the provider confirmed the mailbox), best effort (inferred from available signals), or mx only (the domain accepts mail but the individual mailbox could not be confirmed).

Why verify email addresses?

Sending to bad addresses is expensive. High bounce rates damage your sender reputation, push your mail into spam folders, and can get your domain throttled by inbox providers. Verifying email at the point of capture — a signup form, a checkout, an imported list — keeps your data clean and your deliverability high. Use it to check if an email is valid before a cold outreach send, to scrub an old list, or to stop fake signups from disposable addresses.

Privacy

Verification never sends an actual message to the address. It relies on syntax rules, DNS/MX lookups, and SMTP-level conversation with the receiving server — the same handshake a real mail server starts before delivering — without ever completing a send. Note that catch-all domains accept every address by design, so an individual mailbox there can't be confirmed as existing.

Frequently Asked Questions

Common questions about the Email Verifier

It runs four layers of checks. First, syntax — is the address shaped correctly. Second, MX records — does the domain have mail servers configured in DNS to receive mail. Third, disposable and role detection — is it a throwaway provider or a shared address like info@ or support@. Fourth, a mailbox check that probes the mail server to see whether the specific mailbox exists, is not found, or sits behind a catch-all domain. The combined result is a single verdict: deliverable, risky, or undeliverable.

A syntax validator only confirms the address looks like name@domain.com. That catches typos but nothing else — a correctly formatted address can still bounce because the mailbox never existed. This tool adds DNS/MX lookups and a live mailbox check, so it tells you whether the address can actually receive mail, not just whether it is well-formed.

No. Verification never delivers an actual email. It uses syntax rules, DNS/MX lookups, and an SMTP-level handshake with the receiving server — the same conversation a sending mail server starts before delivery — but stops before any message is sent. The mailbox owner is not notified and receives nothing.

Risky means the address is technically accepted but uncertain. The most common cause is a catch-all domain, which is configured to accept mail for any address — so the server cannot confirm whether that specific mailbox truly exists. Role addresses (info@, sales@) and disposable providers are also flagged as risky. A risky result is not necessarily bad, but you should treat it with more caution than a confirmed deliverable address.

Sending to invalid addresses causes hard bounces, which hurt your sender reputation and can push your future mail into spam folders or get your domain throttled. Verifying at the point of capture — signup forms, checkouts, imported lists — keeps bounce rates low, protects deliverability, and stops fake or disposable signups from polluting your data.

This free tool verifies one address at a time. To validate entire lists in bulk or verify addresses programmatically inside your own signup flow or backend, use the pushmail.dev API, which exposes the same checks over a simple REST endpoint with an API key.
