Two real responses from the Easy Email Verification API. The address in the invalid example has been anonymized.

Valid result

    "did_you_mean": "",
    "success": true,
    "message": "Processing time: 454 ms",
    "http_code": "200"
}

The processing times shown come from these two examples; they are not a service-level commitment.

Request example

curl --location \
'https://api.easyemailverification.com/v1/verify?email=info@easyemailverification.com&apikey=YOUR_API_KEY'

success: true and http_code: "200" mean the API request was processed — not that the address is valid. The verification outcome is in the result field: the invalid example is a successful request whose result is invalid.

Replace YOUR_API_KEY with a key created in your dashboard under Developer → API Settings. Keep API keys secret: anyone with your key can use your verification credits.

What Our Email Verification Checks

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

Address

Syntax validationChecks that the address follows email format rules (RFC).
Typo suggestionReturns a correction in did_you_mean when a likely typo is detected.

Domain and mail server

Domain validationChecks that the domain exists.
MX record verificationFinds the mail servers that receive email for the domain.
Mail server connectivityConnects to the domain's mail server.

Mailbox

SMTP mailbox verificationAsks the mail server whether the mailbox exists — without sending an email.
Catch-all detectionIdentifies domains that accept email for any address (accept_all).

Address type

Disposable email detectionIdentifies temporary email services.
Role-based detectionIdentifies addresses such as info@, sales@ or support@.
Free provider detectionIdentifies addresses on free services such as Gmail, Yahoo or Hotmail.

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 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.

Reasons

Reason	Description
`invalid_email`	The email syntax is invalid (not according to RFC standards).
`invalid_domain`	The domain of the address does not exist.
`rejected_email`	The SMTP server rejected the address: the account does not exist on the receiving server.
`accepted_email`	The SMTP server accepted the address.
`no_connect`	Could not connect to the receiving SMTP server.
`timeout`	The session timed out because the receiving mail server responded too slowly.
`unavailable_smtp`	The receiving SMTP server was not available to process the request.
`unexpected_error`	An unexpected error occurred on the receiving SMTP server.
`no_mx_record`	The domain has no MX record.
`temporarily_blocked`	The address is temporarily greylisted.
`exceeded_storage`	The account on the receiving server has exceeded its storage allocation.

Useful fields

Field	Description
`disposable`	The address belongs to a disposable (temporary) email service.
`accept_all`	The domain appears to accept email for any recipient (catch-all), so the mailbox cannot be confirmed.
`role`	Role-based address such as info@, sales@ or support@.
`free`	The address is hosted by a free email provider.
`safe_to_send`	Whether the verification logic considers the address safe to send to.
`did_you_mean`	A suggested correction when a likely typo is detected.
`mx_record`	The mail exchanger identified during verification.

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.

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.
