Email & MX Validator

Check whether an email address is well-formed and whether its domain can actually receive mail. Runs a syntax breakdown plus a live MX lookup over DNS-over-HTTPS.

Queries run live against Cloudflare's public DNS-over-HTTPS resolver (1.1.1.1). Nothing is sent to UniCybers servers and no lookups are stored. This checks syntax and whether the domain accepts mail. It does not confirm that the specific mailbox exists or is active.
