About email validation
Validating an address means confirming it is worth sending to before you hit send. Real validation has layers: the syntax must be well-formed, the domain must publish MX records so it can actually receive mail, and the address should not be disposable or a low-value role account.
This validator runs all of those checks live — the MX lookup happens over DNS at the moment you run it — and combines them into a transparent 0-100 score and risk band. It does not perform an SMTP mailbox probe (which is unreliable and blocked on many networks), so treat a high score as strong deliverability confidence, and confirm the exact mailbox with a dedicated existence check when it matters.

What does the email address validator check?
It validates the syntax, resolves the domain's MX records live to confirm it can receive mail, detects disposable and role-based addresses, identifies free versus business providers, and suggests a fix for likely typos — all combined into a 0-100 score and risk band.
Does it confirm the mailbox actually exists?
No. It does not run an SMTP mailbox probe, which is unreliable and blocked on many networks. A high score means strong deliverability confidence; use a dedicated mailbox existence check when you need to confirm a specific inbox.
How is the score calculated?
It starts at 100 and deducts for real risk signals — no MX record, a disposable domain, a likely typo, a role-based or free-provider address — so the score is transparent, not a black box.
What is a disposable email?
A throwaway address from a temporary-mail service (like mailinator.com). They are used to bypass sign-ups and churn or bounce quickly, so they are flagged as high risk.
Why flag role-based addresses?
Addresses like info@ or support@ reach a group rather than a person, are often unmonitored, and are more likely to generate spam complaints — so they carry extra risk for marketing sends.
Is the MX lookup live?
Yes. The domain's MX records are resolved over DNS-over-HTTPS at the moment you run the check — no cached or sample data.
