email_verify

com.temsor/api · Verify this server

Checks an e-mail address: syntax, whether the domain can actually receive mail, disposable and role-account detection, and typo correction. No SMTP probing. Most competitors connect to the target server and try RCPT TO, which sounds thorough but produces a confident-looking number you cannot trust: most servers are catch-all, the big providers refuse to answer, and doing it in bulk gets the probing IP blacklisted. We report only what is provable — whether the domain has a mail exchanger, whether it is a known disposable service, whether the mailbox belongs to a role rather than a person, and whether the domain looks like a typo of a common one (gmial.com → gmail.com). Addresses are also normalised, so Gmail dots and +tags stop creating duplicate signups.
