Stop Paying for Expensive Email Validation Services

You're currently paying: ZeroBounce ($0.008/email), NeverBounce ($0.008/email), Hunter.io ($0.01/email), Clearout ($0.006/email).

What if you could validate emails for less?

The Email Validation API provides comprehensive email validation at a fraction of the cost:

• Syntax validation (RFC-compliant)
• MX record verification
• SPF/DMARC detection
• Disposable email detection (1,000+ domains)
• Free provider identification (Gmail, Yahoo, Outlook, etc.)
• Role-based address detection (info@, support@, sales@)
• Deliverability scoring (0-100)
• Bulk validation support

Pay only for what you use. No monthly subscriptions. No minimum commitments.

Why Choose This Over Traditional Validators

1. Pay-Per-Email, Not Per-Month

Traditional tools: $50-$500/month for your agency.

This actor: Pay per validation. Validate 1,000 emails for ~$5. Validate 10,000 for ~$40.

Validate 50,000 emails/month and still pay less than a ZeroBounce subscription.

2. Comprehensive Checks in One API Call

Stop making multiple API calls. Get syntax, MX, SPF, DMARC, deliverability, and risk flags in one response.

Feed it directly into your CRM, email platform, or lead generation workflow.

3. Real-Time or Bulk Mode

• Real-time: Validate emails at point of entry (forms, signups)
• Bulk: Clean entire lists before campaigns
• Webhook: Get results delivered automatically when done

4. No False Positives

Unlike basic validators, we check actual MX records and authentication protocols. If an email passes, it's deliverable.

Quick Start Examples

Example 1: Validate Single Email

{
  "emails": ["john.doe@gmail.com"],
  "checkMx": true,
  "checkDisposable": true
}

Example 2: Bulk Validation (Lead List)

{
  "emails": [
    "lead1@company.com",
    "lead2@startup.io",
    "lead3@enterprise.net"
  ],
  "checkMx": true,
  "checkSmtp": false,
  "checkDisposable": true
}

Example 3: With Webhook (Zapier/Make/n8n)

{
  "emails": ["lead@example.com"],
  "webhookUrl": "https://hooks.zapier.com/hooks/catch/12345/abcdef/"
}

Results automatically POST to your webhook when complete.

Scoring System

The quality score (0-100) is calculated based on:

Has DMARC record	+10	Advanced email security
Deliverable	+25	Passes all deliverability checks
Not disposable	+5	Not a temporary email

Not role-based	+2	Personal address (decision maker)

Score Interpretation:

• 90-100: Excellent - High confidence, proceed with outreach
• 70-89: Good - Likely valid, safe to email
• 50-69: Fair - Some risk, consider verification
• Below 50: Poor - High risk, avoid sending
