Email Validator API — Bulk Email Verification & SMTP Check

Verify email addresses in bulk with syntax validation, MX record lookup, disposable email detection, role-based detection, and live SMTP handshake verification. Returns a deliverability score (0–100) for every address. No API key, no monthly subscription — pay only for what you verify.

First 10 verifications free on every run. Then $0.002 per email.

Why use this email verifier?

Cold email and marketing campaigns die when your bounce rate climbs. Mailbox providers (Gmail, Outlook, Yahoo) punish senders with high bounces by pushing mail to spam. This actor cleans your list before you hit send, protecting your sender reputation and inbox placement.

Compare the cost:

Service	50,000 emails
ZeroBounce	~$350
NeverBounce	~$250
Hunter.io	~$200
This actor	~$100

What it checks

• ✅ Syntax validation — catches typos like gmial.com, malformed addresses
• ✅ MX record lookup — confirms the domain actually accepts email
• ✅ Disposable detection — flags temp-mail.org, guerrillamail, mailinator, and 15+ throwaway domains
• ✅ Role-based detection — identifies info@, sales@, support@, noreply@ addresses
• ✅ SMTP handshake — connects to the mail server and verifies the mailbox exists
• ✅ Quality score — a single 0–100 number you can threshold on

FAQ

Does it need an API key? No. Just add it and run.

How accurate is SMTP verification? Very accurate for most providers. Catch-all domains (which accept every address) are flagged so you can treat them carefully.

Can I schedule recurring runs? Yes — use Apify's built-in scheduler or webhooks to validate signups automatically.

What formats can I export? JSON, JSONL, CSV, Excel, XML, or RSS.
