Bulk Email Validator & MX/SPF/DMARC Deliverability Verifier ($1.50 / 1K)

Validate high-volume email lists for syntax, disposable inboxes, role accounts, live DNS MX records via Google DoH, SPF & DMARC authentication, mail gateway fingerprinting (Google Workspace, Microsoft 365, Proofpoint, etc.), and composite deliverability risk scoring (0–100).

Never send cold outbound campaigns or automated emails to dead inboxes, temporary spamtraps, or unauthenticated domains. Protect your sender reputation, maximize inbox placement, and avoid blacklists—at a fraction of the cost of legacy SaaS verification tools.

High-Intent B2B Playbooks (Copy-Paste Inputs)

1. Cold Email Outbound Campaign Scrubbing (Zero-Bounce Guarantee)

Filter out invalid syntax, disposable spamtraps, and domains with missing MX records before uploading lead lists to Instantly, Smartlead, or Lemlist:

{
  "emails": [
    "alex.turner@stripe.com",
    "sarah.connor@acme-industrial.com",
    "test_lead_8899@mailinator.com",
    "support@shopify.com",
    "invalid-user-format"
  ],
  "checkMx": true,
  "checkSpfDmarc": true,
  "checkDisposable": true,
  "checkRoleAccount": true,
  "dohProvider": "google",
  "maxItems": 1000
}

2. High-Deliverability Security & Gateway Audit (Identify Google & M365 Inboxes)

Fingerprint destination mail servers to tailor email delivery timing and warm-up settings based on whether leads use Google Workspace, Microsoft 365, or strict enterprise gateways like Proofpoint / Mimecast:

{
  "emails": [
    "founder@apify.com",
    "security@github.com",
    "procurement@lockheedmartin.com",
    "cfo@walmart.com"
  ],
  "checkMx": true,
  "checkSpfDmarc": true,
  "checkDisposable": true,
  "checkRoleAccount": false,
  "dohProvider": "google"
}

3. Rapid Disposable & Role-Account Pre-Filter (Low-Latency Pass)

Validate user registration inputs or form submissions instantly without waiting on full SPF/DMARC TXT resolution:

{
  "emails": [
    "user1@temp-mail.org",
    "sales@targetcompany.com",
    "real_customer@gmail.com"
  ],
  "checkMx": true,
  "checkSpfDmarc": false,
  "checkDisposable": true,
  "checkRoleAccount": true
}
