About email validation

Email validation confirms an address is worth sending to before you hit send. Real validation is layered: the syntax must be well-formed, the domain must publish MX records so it can receive mail, and the address should not be disposable or an obvious typo.

This validator runs those checks live and combines them into a clear valid/invalid verdict with a 0-100 score and the reasoning. It does not run an SMTP mailbox probe (unreliable and widely blocked), so a valid result means strong deliverability confidence — confirm a specific mailbox with the existence checker when it matters.

FREQUENTLY ASKED QUESTIONS

Got Questions? We Have Answers.

What does email validation check?

That the syntax is well-formed, the domain has live MX records so it can receive mail, and the address is not disposable, role-based or an obvious typo.

Does it confirm the mailbox exists?

No SMTP mailbox probe is run (it is unreliable and widely blocked), so a valid result means strong deliverability confidence. Use the existence checker for a specific mailbox.

How does this differ from the Email Address Validator?

They share the same engine and results; this is the generically named entry point for the same real-time validation.

Is the MX lookup live?

Yes. Records are resolved over DNS-over-HTTPS at the moment you validate the address.
