Bulk Email Verifier: Syntax, DNS MX, Disposable, Role & Catch-All Checker

Verify B2B and B2C email lists in bulk without sending a single email: check RFC 5322 syntax, live DNS MX records, mail server provider (Google Workspace, Microsoft 365, Cloudflare, Proofpoint, Mimecast, ProtonMail, Zoho), SPF & DMARC records, disposable email providers, role-based accounts, Levenshtein typo suggestions (gmial.com → gmail.com), Gravatar profiles, and a 0–100 Deliverability Score.

Key Features

Live DNS MX, SPF & DMARC Verification: Resolves MX records with priority ordering, identifies the email gateway/ESP, and verifies v=spf1 and _dmarc policies.
Disposable, Free & Role Account Detection: Flags burner/temporary inbox providers (Mailinator, Yopmail, GuerrillaMail, 10MinuteMail, etc.), free webmail providers, and role-based addresses (support@, info@, sales@, billing@).
Smart Typo Suggestion: Detects common domain misspellings via Levenshtein distance and suggests the corrected address.
Gravatar Signal: Checks whether the email hash resolves to an active Gravatar profile.

Example Input

{
  "emails": [
    "support@shopify.com",
    "press@stripe.com",
    "temp.user@mailinator.com",
    "founder@gmial.com"
  ],
  "checkGravatar": true
}
