Bulk Email Verification & Validation API ($0.50/1K)

Assess email addresses in bulk with no API key required. Check list-quality signals before campaigns and flag records that need review. Results are risk signals, not proof that a mailbox is owned, reachable, or able to receive a particular message.

What it does

For each email address, the actor checks:

• Syntax validation - RFC-compliant email format check
• MX record lookup - Reports whether DNS mail-exchanger records are configured for the domain
• Disposable domain detection - Flags temporary/throwaway email services (Mailinator, Guerrilla Mail, etc.)
• Free provider detection - Identifies Gmail, Yahoo, Outlook, etc.
• Role account detection - Flags generic addresses (info@, admin@, support@, etc.)
• Optional catch-all signal - Reports catch-all behavior only when SMTP checking observes it
• Domain typo suggestions - Suggests corrections (gmial.com -> gmail.com)
• Optional SMTP signal - Attempts to observe whether a mail server accepts the address, subject to provider blocking, greylisting, catch-all behavior, and other inconclusive responses

Use cases

• CRM cleanup - Flag structurally invalid, disposable, or domain-risk records for review
• Lead-list checks - Assess scraped email lists before outreach
• Email campaign prep - Identify obvious list-quality risks before sending
• Data quality - Flag disposable, role-based, and catch-all addresses
• List hygiene - Identify free vs business email addresses

Input

Field	Type	Description
emails	string[]	Email addresses to validate
enableSMTP	boolean	Enable SMTP reachability check (default: false)
maxResults	integer	Maximum paid dataset items (default demo: 5; max: 100,000)
concurrency	integer	Parallel validations (default: 5, max: 20)

Output

Each email produces a result with:

valid means the syntax is valid, an MX record exists, and the domain is not flagged as disposable. It does not mean the mailbox or owner was verified.

{
  "email": "user@gmail.com",
  "valid": true,
  "syntaxValid": true,
  "mxFound": true,
  "disposable": false,
  "freeProvider": true,
  "roleAccount": false,
  "catchAll": false,
  "domain": "gmail.com",
  "localPart": "user",
  "mxRecords": "gmail-smtp-in.l.google.com, alt1.gmail-smtp-in.l.google.com"
}

Use with AI Assistants (MCP)

This actor works as an MCP tool with Claude Desktop, Cursor, and other MCP clients.

Setup: Add this to your MCP client configuration:

{
  "mcpServers": {
    "email-validator": {
      "url": "https://mcp.apify.com?tools=pink_comic/email-validation-checker"
    }
  }
}

Then ask your AI: "Validate these email addresses: john@example.com, sales@acme.com" -- it will run the validator and return results.

Pricing and first run

• $0.0005 per result ($0.50 per 1,000)
• No start fee
• The default five-address demo costs at most $0.0025
• maxResults and an Apify maximum-total-charge limit both cap paid output
• Bulk Apify output is written in bounded 1,000-row batches so large advertised workflows do not depend on one oversized dataset request

No API key or external account is needed.

Evidence limits

SMTP checking is disabled by default because datacenter IPs are frequently blocked, servers can greylist requests, and catch-all/provider policies can produce misleading or inconclusive signals. Syntax, MX, and disposable-domain checks establish domain-level risk indicators only.

The output does not prove mailbox ownership, consent, live reachability, inbox placement, message delivery, or compliance with anti-spam rules. Treat smtpReachable as a point-in-time signal and valid as the documented structural/domain rule—not a deliverability guarantee.
