Paste any professional email. Nothing is ever sent to it.

What is email verification?

Email verification checks whether an email address is real and safe to send to, without sending anything to it. It works in layers: confirm the address is well-formed, inspect the domain for published mail routes or explicit refusal, and finally confirm the specific mailbox exists with a live provider lookup. The first two layers are free; DNS does not test server availability, and the last, mailbox-level layer is the one that needs a live check. Verifying before you send keeps your bounce rate low and protects your sender reputation, which is what keeps future emails landing in the inbox.

What each check means

The verifier reports each signal separately, so you see not just a verdict but why. Everything except the live mailbox check is free and needs no account.

CheckWhat it tells youCost
Valid formatThe address has a valid local part, @, and domain syntax. This check does not establish that the domain or mailbox exists.Free
Domain mail routingChecks published MX records and possible A/AAAA fallback addresses. Null MX explicitly refuses email. DNS failures remain unknown; server availability is not tested.Free
Disposable addressThe domain is a known temporary or throwaway mailbox provider, a strong risk signal for signups and outreach.Free
Role addressA shared, functional mailbox (info@, sales@, support@) rather than a specific person. It delivers, but rarely to who you want.Free
Likely typoThe domain looks like a mistyped popular provider (gmial.com), with the correction suggested.Free
Live mailbox checkConfirms the exact mailbox exists, in real time, via the mail provider. The one thing a free tool can't do; it costs one credit.Paid

How to read the verdict

Looks deliverable

Valid format and published mail servers. Server availability and the specific mailbox still need a live check.

Risky

Something needs a second look: a disposable address, a role mailbox, or a likely typo.

Undeliverable

The domain explicitly refuses email with null MX, or DNS has no MX, A or AAAA records for mail routing.

Mail server unconfirmed

No MX is published. An A/AAAA address is a possible fallback, but it may only serve a website and have no mail server.

Domain check unavailable

DNS failed or timed out. Retry the check; an outage is not proof that the address is bad.

Invalid format

The address is not well-formed, so it cannot be a real email.

How to verify an email address

  1. 01

    Paste the email address

    Enter any professional email (like jordan@acme.com). Nothing is ever sent to it, so there is no risk of a bounce.

  2. 02

    See the checks, instantly

    The format and risk flags are checked in your browser; the domain's mail servers are looked up live. You get a clear verdict in a second, free.

  3. 03

    Confirm the mailbox when it matters

    For an address you're about to rely on, run the live mailbox check to confirm it exists in real time. One credit, refunded if there's no verdict.

Questions

Is this email verifier free?

Yes. Checking an email's format, its domain's DNS mail routing, and its disposable, role and typo risks is completely free and needs no sign-up. The only paid step is the optional live mailbox check, which confirms the exact address exists in real time and costs one credit (new accounts start with free credits).

How does email verification work?

It runs in layers. First it checks the address is well-formed. Then it inspects the domain's DNS mail routing: MX records, explicit refusal through null MX, or a possible A/AAAA fallback. DNS alone does not establish that a server is listening or that a mailbox exists. Failed DNS lookups are reported as unavailable so you can retry. To confirm the one specific mailbox exists, a live check queries the mail provider in real time, which is the paid step.

Will verifying an email send anything to it or make it bounce?

No. Verification is a lookup, never a send. The free checks query DNS for the domain's mail servers; the live check probes the provider without delivering a message. Nothing lands in the person's inbox, and nothing counts as a bounce.

What's the difference between DNS mail routing and a live mailbox check?

DNS mail routing describes published records, not server availability. An MX record advertises a mail server; an A/AAAA fallback may only be a website. A live mailbox check queries the provider about the exact address and reports its confidence, with limits for catch-all and protected mailboxes.

What is a disposable or throwaway email address?

A disposable address comes from a temporary-mailbox service (like Mailinator or 10MinuteMail) that anyone can use for a few minutes and abandon. They deliver, so a live check calls them valid, but they are a strong red flag on signups and outreach because there is no real person behind them. The free checker flags known disposable domains for you.

What is a role-based email address?

A role address is a shared, functional mailbox tied to a function rather than a person: info@, sales@, support@, admin@. It is deliverable, but it usually reaches a team inbox, not the individual you are trying to contact, and role addresses have higher complaint rates in cold outreach. The checker flags them so you can decide.

Can you detect a catch-all domain?

A catch-all (or accept-all) domain accepts mail to every possible address, so no verifier, free or paid, can prove a specific mailbox exists there: the domain says yes to everything. The free check will show the published mail route, and the live check returns its confidence honestly rather than a false certainty. Treat a catch-all result as 'send with care', not 'confirmed'.

How accurate is email verification?

Malformed addresses and an explicit null MX are clear failures. Temporary DNS failures are inconclusive, and published mail routing alone does not prove a server or mailbox works. Confirming a specific mailbox is highly accurate for most providers but can never be 100% (catch-all domains and privacy-protected providers are honest exceptions). The right way to read any verifier is as strong risk reduction, not a guarantee, which is why a good result reports its confidence rather than a blanket 'valid'.

What's the difference between an email verifier and an email finder?

A verifier checks an address you already have. A finder discovers an address you don't: you know the person and company, and it returns their verified professional email. Use the verifier to clean a list before you send; use PeopleSearch.im's finder when you have a name but no address.

Need the address, not just a check?

Describe the people you're looking for in plain English and PeopleSearch.im finds them and their verified professional emails directly, no guessing required.
