VerifyEmail

VerifyEmail is a productivity tool for people who send email: it checks whether an email address is real and will accept mail before you write to it. Give it one address and it runs the full set of checks: syntax, whether the domain exists and publishes MX records, a live probe of the mailbox on the recipient's mail server, and detection of disposable providers and role addresses such as info@ or postmaster@.

Every check ends in one of four verdicts. Deliverable means the mailbox accepts mail. Undeliverable means mail to it will bounce, for example because the address is malformed, the domain has no mail server, or the mailbox does not exist. Risky means the mailbox exists but may still bounce: it is on a catch-all domain, a disposable provider, or a role address. Unknown means the mail server did not give a definite answer, usually because it timed out or greylisted the probe; try again later.

When a mail server is slow the app tells you the check is still running and fetches the finished result for you, rather than guessing. The app signs in with your existing VerifyEmail account and shows the account it is using on request. It verifies one address at a time; bulk lists, DMARC monitoring and blacklist monitoring live in the VerifyEmail web app.
