Email Verifier.

No. The verifier never sends a message to the address it checks, so the person is not contacted and nothing appears in their inbox. It reads public DNS records for the domain and compares the address against published lists of disposable domains and common misspellings.

Valid means the domain accepts mail and nothing flagged the address. Risky means it might work but deserves care: a role inbox, a likely typo, or a domain whose DNS did not answer. Invalid means it should not be mailed: it is malformed, uses a throwaway domain, or its domain has no mail server or refuses all mail.

No. This free verifier runs domain-level checks only: it confirms the domain can receive mail, not that one particular mailbox exists. It says so in the result rather than implying more. A domain that passes these checks can still bounce an address nobody uses, so treat valid as able to receive mail, not as confirmed.

A role address belongs to a function rather than a person, such as info@, sales@, support@ or admin@. These inboxes are usually shared, often filtered, and rarely reply to cold outreach, so the verifier marks them risky. Prefer the address of the named person you want to reach.

A disposable address comes from a throwaway-inbox service that hands out temporary mailboxes, usually to get past a sign-up form. They are abandoned soon after, so mail sent there reaches nobody. The verifier checks the domain against a published list of these services and marks matches invalid.

A null MX is a DNS record a domain publishes to say it accepts no email at all (RFC 7505): a single MX record pointing at a dot. Every message to such a domain bounces, so the verifier marks its addresses invalid. A domain with no MX record but an address record can still receive mail, and is not marked invalid for that.

SPF and DMARC are the records a domain publishes to say who may send its mail and what receivers should do with mail that fails. They tell you how the domain is set up for email. They do not change the verdict on the address, which comes only from the checks listed in the result.

Use email verification in SendCanyon. It verifies lists, segments and uploaded CSV files with the same checks, verifies every import and new contact automatically, and holds risky and invalid contacts out of your campaigns until you choose to include them. Results download as a CSV with your original columns kept.

We keep the domain you checked and the result for 90 days, with your IP address and browser, to prevent abuse. We do not keep the part of the address before the @. Nothing is sent to the address and the person behind it is never contacted.
