Bulk Email Verifier

500 emails per run — scored 0–100 with reasons, typo fixes and provider detection.

Not just valid-or-invalid: every address gets a transparent 0–100 quality score with the exact reasons — disposable domains, role inboxes, gibberish locals, typo'd providers (with one-click "did you mean" fixes) and live MX verification that also identifies the real mail provider behind each domain. Export the full report, or grab valid / risky / invalid as separate files. Found these emails with the URL to Email Extractor? Clean them here before sending, then check your own DNS with the SPF / DKIM / DMARC Checker.

Frequently Asked Questions

How is each email scored from 0 to 100?

Every address starts at 100 and loses points per risk signal: no MX record drops it to 5 (undeliverable), a disposable domain costs 70, gibberish-looking locals cost 30, role-based prefixes cost 25, a likely domain typo costs 20. 80+ is Valid, 40–79 Risky, below 40 Invalid — and every deduction is shown as a reason chip so you know exactly why.

What is the "did you mean" suggestion?

When a domain is within two keystrokes of a major provider — gmial.com, hotmial.com, yahooo.com — the verifier flags it as a probable typo and suggests the correction. These addresses usually come from signup forms and are recoverable customers, not dead leads.

How does gibberish detection work?

Heuristics catch keyboard-mash locals like xk7qzpw93: very low vowel ratios, long consonant runs and high digit density. Such addresses are overwhelmingly fake signups, so they are marked Risky even when the domain itself is fine.

What does the mail provider column tell me?

The verifier reads each domain’s MX hostnames and identifies who actually handles its mail — Google Workspace, Microsoft 365, Zoho, Proton, Mimecast and more. A B2B list that is 80% Google/M365 is healthy; one full of unknown servers deserves caution.

Why is there no catch-all or SMTP mailbox check?

True mailbox-level verification requires opening SMTP connections on port 25, which residential networks, browsers and most cloud hosts (including ours) cannot do — services charging per-verification run dedicated mail infrastructure for it. We are honest about that line: this tool removes the bulk of undeliverable addresses for free; use a paid SMTP verifier for the final pass on high-stakes campaigns.

Is my list uploaded anywhere?

No. Parsing, scoring and exports run entirely in your browser. Only domain names (never full addresses) are sent to Google/Cloudflare DNS-over-HTTPS for MX lookups. Close the tab and nothing persists.
