Email Validator
Validate email addresses with a three-layer check: syntax, MX record, and disposable blocklist. Get instant results online — free with no sign-up.
Layer 1: local regex. Layer 2: MX-record lookup via Cloudflare DNS-over-HTTPS (proves the domain receives mail). Layer 3: Disify for disposable / role / free-provider classification. Even when every layer passes, only the receiving SMTP server can confirm whether a specific mailbox exists — and probing it is anti-spam-blocked everywhere.

What it does
Check an email address against three layers: local regex syntax, DNS resolution + MX record presence, and disposable-mail-service blocklists. Catches typos, fake addresses, and the obvious 10-min email services people use to dodge marketing.
Uses EVA and Disify in parallel — if one is offline, the other still gives a result. Note: even a fully-validated address might still not have a real inbox; only the receiving SMTP server can confirm that, and SMTP probing is anti-spam-blocked.
