Free Email Checker

Verify whether an email address is valid and the mailbox actually exists — with a live check of the receiving mail server. 3 free checks, no signup to start.

3 free checks every 3 hours. No email is ever delivered to the address.

What the email checker does

Unlike a simple format check, this tool confirms whether an email address can actually receive mail. It runs the same multi-stage checks our verification engine uses on full lists:

You get a clear status — valid, invalid, risky or disposable — plus a confidence score, so you know whether it is safe to add the address to your list or send to it.

Checking vs. sending

Verifying an address is not the same as emailing it. The check opens a connection to the mail server and asks whether the mailbox exists, then disconnects — no message is delivered and the owner is never notified. This is how you can safely test addresses before a campaign without risking your sender reputation on invalid contacts.

Need to check more than a few?

This tool gives you 3 free checks to try things out. To verify more addresses, clean an entire mailing list, or check emails automatically at signup, create a free account and get 100 verification credits. Bulk verification handles thousands of emails with 99.5% accuracy, and the real-time API verifies them right inside your signup flow.

Frequently asked questions

How does the email checker work?

It checks syntax, MX records and disposable providers, then performs a live SMTP check to confirm the mailbox exists — without sending a real email.

How many emails can I check for free?

3 addresses for free without signing up. To verify more or clean a whole list, create a free account with 100 credits.

Is checking an email the same as sending one?

No. The check asks the mail server whether the mailbox exists but never delivers a message, so the owner is not notified.
