What it is
VeriDock: the homepage
VeriDock is an email verification service and API that checks whether email addresses are real and can receive mail before you send to them. It runs syntax, DNS, MX record and live SMTP checks on each address, detects catch-all domains, disposable inboxes and role accounts, and returns one of four statuses (deliverable, undeliverable, risky, or unknown) with a reason code and score. Users can verify single addresses through a free web checker, upload CSV lists for bulk verification from the dashboard, or integrate the REST API into signup forms and CRMs. The service is built for marketers cleaning email lists and developers adding verification to their applications.

Quick answers
How does email verification work?
VeriDock runs syntax, domain, MX record and SMTP checks on each address. It connects to the receiving mail server and asks if the mailbox exists, then disconnects before sending any message. It also flags disposable domains, role addresses like info@, and catch-all domains that accept mail for any address.
Can I verify an email without sending an email?
Yes. VeriDock opens an SMTP conversation with the receiving server and asks whether the mailbox exists, then closes the connection before any message is sent. The recipient never sees anything.
What is a catch-all email address?
A catch-all address is on a domain whose server accepts mail for every address, real or not. Because the server says yes to everything, no SMTP check can confirm the mailbox exists, so VeriDock returns risky with the reason catch_all instead of claiming it is deliverable.
Why do email verification APIs return unknown?
Some mail servers time out, temporarily refuse connections (greylisting) or will not confirm mailboxes to outside servers. When that happens there is no honest answer to give, so VeriDock retries and then returns unknown. Unknown results are never billed.
Is email validation different from email verification?
Usually, yes. Validation normally means checking the format of an address and sometimes its domain. Verification goes further and asks the mail server whether the mailbox exists. An address can pass validation and still bounce.
