📧 Email Verifier — Deliverability Checker

ZeroBounce-style email validation API: verify any email address and get a 0–100 deliverability score plus detailed diagnostics, without needing your own SMTP infrastructure.

🚀 Quick Start

1. Click Try for free (or Run) on this Actor
2. Paste your email list (one per line) into the emails field
3. Run — get a verdict for every address instantly

No input? The Actor runs a demo batch so you can see the output format immediately.

🔍 What it checks

Check	Method
Format validation	RFC-style regex
Domain validity	MX record lookup (DNS)
Disposable email detection	30+ known disposable domains (mailinator, 10minutemail…)
Free provider flag	Gmail, Yahoo, Outlook, Naver, Proton… (30+)
Spelling check	Detects gmail.co → gmail.com typos with suggestions
SMTP handshake (optional)	Live connect to MX host, MAIL FROM/RCPT TO

📊 Output

Every email returns structured JSON:

{
  "email": "john.doe@gmail.com",
  "status": "valid",
  "score": 95,
  "reason": "syntax_and_mx_valid",
  "domain": "gmail.com",
  "mxFound": true,
  "mxHosts": ["gmail-smtp-in.l.google.com"],
  "isDisposable": false,
  "isFreeProvider": true,
  "smtpCheck": "skipped",
  "spelling": {"typo": false, "suggestion": null}
}

Plus a run summary (total / valid / invalid / average score).

💡 Use cases

• Marketing — clean your lists before a campaign, cut bounce rates
• Sales — verify lead emails before outreach sequences
• Data quality — dedupe and validate CRM imports
• Signup flows — catch disposable addresses at registration
• Email hygiene for agencies — batch-verify client lists

⚙️ Technical notes

• Status values: valid, invalid, unknown (SMTP probe blocked)
• Score 0–100: syntax + MX + disposable + SMTP signals combined
• SMTP check is off by default — many servers block probes and it slows runs; enable only when you need the extra signal
• Public DNS only, no API keys needed

Inspired by commercial email verification services (ZeroBounce, NeverBounce, Hunter).

🔌 Use inside Clay (bring-your-own enrichment)

Clay users pay only orchestration Actions when they bring their own provider keys. Call this Actor as an HTTP API email verification enrichment column:

1. In Clay, add an HTTP API column (POST https://api.apify.com/v2/acts/H5c7CcrE77JNLSh5P/runs?token=YOUR_APIFY_TOKEN)
2. Body: the same JSON you would paste into the Input tab
3. Map the returned dataset rows back into your table

At ~$0.001-0.008 per result with zero seat minimums, this is typically 10-50x cheaper per enriched row than native Clay data credits.
