Validate an email address online — syntax, disposable/temporary detection, role and free-provider flags, typo suggestions and optional MX check.
Validate and classify an email address: syntax, disposable/temporary providers, role accounts (info@, admin@), free providers and common typo corrections. Tick the MX option to check the domain's mail servers live via DNS-over-HTTPS.
It looks up the domain's mail-exchange (MX) records. No MX usually means the domain cannot receive email, so the address is undeliverable.
Disposable addresses (mailinator, etc.) and shared role inboxes hurt sign-up quality and deliverability, so many forms reject or down-rank them.
The tool above runs in your browser. To run the same check on your server, at scale, call the Email Validation API — one GET request, any language.
