What Our Email Verification Checks

Each address goes through a sequence of checks, from its format to the mailbox.

Syntax validation
Typo suggestion
Domain validation
MX record verification
Mail server connectivity
SMTP mailbox verification
Catch-all detection
Disposable email detection
Role-based detection
Free provider detection

Check a single address and see its result explained

Limitations

Mailbox verification is performed without sending an email. Some mail servers may not disclose mailbox existence or may temporarily block verification. In these cases, the result may be returned as Unknown. Addresses on catch-all domains cannot be confirmed individually, and a verification result is not a guarantee that a future message will be delivered.

How email verification works →

How to Read the Results

Every verification returns a result — the overall outcome — and a reason, the technical cause behind it.

Result	What it means	Suggested use
`valid`	The address passed the applicable verification checks and the mailbox was accepted by the remote mail server.	Keep it for sending. Also review flags such as role, accept_all and disposable.
`invalid`	The address failed validation or the remote mail server rejected the mailbox.	Remove it from your list or ask the person to correct it.
`unknown`	The verification could not reach a reliable conclusion, for example because of a timeout, temporary blocking, SMTP unavailability or other remote mail server behavior.	Do not treat it as invalid. Keep it apart and verify it again later.

Unknown does not mean invalid.

Verify One Address, a Whole List, or via API

Single email check

Check any address in the online email checker — no code required.

Open the email checker

Bulk email verification

Upload a CSV or TXT file to verify an entire email list. Lists are processed asynchronously: follow the status and download the results when they are ready. Result files are kept for 30 days and then deleted.

The Bulk API follows the same flow: upload, status, list, download and delete.

Clean a whole list before your campaign

Email verification API

A REST API that returns JSON, for real-time email validation in signup forms, apps and CRMs. HTTP status codes identify issues such as an invalid API key (401), exhausted quota (402) or rate limiting (429).

Email Verification FAQ

Is an email sent to the address during verification?

No. Mailbox verification is performed over SMTP without sending an email.

Does “unknown” mean the address is invalid?

No. Unknown means the verification could not reach a reliable conclusion — for example because of a timeout, temporary blocking (greylisting) or an unavailable mail server. You can verify the address again later.

Can every mailbox be confirmed?

No. Some mail servers may not disclose mailbox existence or may temporarily block verification; in these cases the result may be Unknown. On catch-all domains, individual mailboxes cannot be confirmed.

What is a catch-all (accept-all) domain?

A domain whose mail server accepts messages for any address. Because every address is accepted, individual mailboxes on these domains cannot be confirmed; the API reports this with accept_all.

Is there a free plan?

Yes. Verify up to 50 email addresses every day for free. No credit card required. The free plan does not expire. A free account is required.

Do you store the email addresses I verify?

Addresses verified one at a time — in the email checker or through the API — are not retained. For bulk verification, result files are kept for 30 days so you can download them and are then deleted. Account data (name, email and credentials) is stored to provide the service.
